Mackay Renal Unit UV Sterilisation System

Case Study

Customer: Queensland Health

Completion Date: 11/02/2014

Location: Mackay, QLD

Specifications & Features:

Dowdens Pumping & Water Treatment have successfully designed, installed and commissioned a specialised Ultraviolet filtration system for the Queensland Health Mackay Renal Unit.

Project Requirements: The original system operated by pumping town water to individual filtering stations where the water would pass through a 5 micron, 1 micron and carbon filter on its way to the dialysis machine (which has an internal reverse osmosis filter).

The issue Dowdens faced was the original system filters were only lasting between 5 - 15 hours, and by this stage they were black and needed to be replaced!

After reviewing detailed water test results, Dowdens designed a compact, reliable system where the existing pump was upgraded, a water softening unit was added to remove iron, calcium and manganese. Large cartridge filters were also installed to pre-filter the water before it entered a dedicated UV steriliser.

Using the above system the Mackay Renal Unit now only needs to replace the systems filters every 7 to 10 days - saving thousands of dollars in ongoing system maintenance costs!

Cannonvale Medical Centre Water Treatment System post Cyclone Debbie

Wednesday, 19 April 2017

Severe Tropical Cyclone Debbie made landfall near Airlie Beach on the Nth QLD coast 28th March 2017. It was a slow-moving category 4 system that generated wind gusts exceeding 160 km/hr, heavy rainfall and storm surges along the Nth QLD coastline. 27 hours later, after having tracked inland over Airlie Beach, Proserpine, Cannonvale and Collinsville it was downgraded to a Tropical Low. Dowdens Pumping & Water Treatment's Proserpine Branch is again open for business.

Cannonvale was amongst the hardest hit regions during Cyclone Debbie, so it was no surprise to Dowdens Pumping & Water Treatment's Proserpine Branch to hear Queensland Health had been advised they couldn't be guaranteed potable water supply to their Whitsunday Community Health Centre located in Cannonvale immediately after Cyclone Debbie.

Luckily Dowdens Pumping & Water Treatment's Head Office in Mackay had a portable Ultrafiltration Treatment System available, capable of supplying up to 70,000 litres of potable water per day. Queensland Health and the Whitsunday Community Health Centre in Cannonvale instructed Dowdens Pumping to supply/install the unit immediately on a temporary 'Hire' agreement in-case all mains water supply was lost.

There were two water sources available at the time - the mains water supply or bore water from the Proserpine Hospital. Queensland Health instructed Dowdens to connect the UF Treatment System to the bore water supply, in an effort to remain as self-sufficient as possible post-Cyclone Debbie.

PURION - Water Treatment Products by the Dowdens Group

Dowdens Pumping have previously completed numerous bore water filtration systems treating bore water with our own brand of PURION Iron Removal Filters, so this emergency UF Treatment System was quick and easy to install. PURION Iron Removal Filters pre-treat the bore water before running it through the Ultrafiltration System which then doses the filtrate with liquid chlorine to further disinfect.

Once treated Dowdens Pumping manually transported numerous loads of the potable water from the Proserpine Hospital (where the UF System was installed) directly to the Whitsunday Community Health Centre in Cannonvale, where it was stored in a potable water grade storage tank. The treated water was then used to supply the medical centre. The entire supply/installation and commissioning was successfully completed on Saturday 1st of April - only 4 days after Cyclone Debbie had hit.

If you are ever in need of potable water during a storm or emergency contact Dowdens Pumping & Water Treatment. Dowdens only require access to a reasonable source of water (bore, dam, creek) and power (generator or mains power) and we can guarantee same day potable water supply, in any situation!

Game changing GRUNDFOS SCALA2 PUMPS now at Dowdens

Tuesday, 14 March 2017

Dowdens Pumping & Water Treatment are your local pump experts and are Authorised Grundfos MASTER DEALERS. Dowdens are Mackay's ONLY Authorised Grundfos MASTER DEALERS & Dowdens Rockhampton branch is also an Authorised Grundfos MASTER DEALERS. Grundfos pumps are market leaders, committed to providing new and innovative products that take comfort and simplicity to the next level, for these reasons we sell and recommend the new SCALA2 domestic pump.

Grundfos has long been regarded for their high quality and reliable pumps. The Grundfos SCALA2 takes design innovation, comfort and simplicity to the next level and is set to be a game changer in domestic boosting. The NEW Grundfos SCALA2 is a robust, fully integrated, self-priming pump suitable for use from both above and below ground water sources. The compact system features a pump, motor, tank, sensor, drive and non-return valve in one compact unit that is quick and easy to install.

The SCALA2 is an energy efficient pump featuring an integrated speed controller that ensures constant water pressure regardless of variations in demand or inlet pressure. For those living in areas of poor power supply or those that are sometime affected by power outages, the SCALA2 can also be run on a generator, due to its ability to be able to handle varying voltages.

The variable speed controller also matches the power consumption with the required water output, which also helps to conserve energy and reduce your energy bills. To protect the pump and help ensure a long life, the SCALA2 includes a range of protective features. Dry run protection automatically stops operation when the water source runs out, to help prevent damage, and the anti-cycling feature detects any unnatural cycling and alerts the user via the protection indicator on the control panel.

Another unique benefit of the SCALA2 is its quiet operation, thanks to the permanent magnet motor and water cooling technology. The high efficiency motor is significantly quieter than traditional speed-controlled motors and the SCALA2 is cooled by the water it pumps, eliminating the need for a noisy fan. This makes the SCALA2 one of the quietest domestic boosting pumps currently available on the market.

For ease of selection, the SCALA2 suits most domestic pressure boosting applications and is capable of supplying water for small single level homes up to larger multi-storey homes.

Water Treatment System (Ultrapure Water Production)

Case Study

Customer: Sullivan Nicolaides Pathology

Location: Bowen Hills, QLD

Specifications & Features:

Sullivan Nicolaides Pathology

Dowdens Pumping & Water Treatment's Brisbane branch has built a strong relationship with Sullivan Nicolaides Pathology (SNP) after more than 25 years of providing high purity water treatment systems / solutions for 22 of their Commercial Testing Pathology laboratories - from as far north as Cairns, down south to Coffs Harbour and everywhere in between. The majority of Dowdens Pumping & Water Treatment's high purity water treatment systems are used primarily in Sullivan Nicolaides blood testing machines. SNP was formed in 1956 when Dr John Sullivan started a small pathology practice to service local families in and around Brisbane. Dr Nick Nicolaides joined him 18 months later and since then, it has grown to one of the largest and most trusted pathology practices in Australia.

The PROBLEM:

Tap or 'town' water contains many substances that if left untreated, can react with the reagents used in controlled laboratory tests, causing positive or negative interference which leads to unreliable test results. Cations such as sodium, calcium, magnesium or iron; anions such as bicarbonate, chloride and sulfate; and other inorganic ions, are commonly found in tap water. A number of other contaminants - such as pyrogens, nucleases, alkaline phosphatase and endotoxins may be present. As they are not harmful for human consumption, they are not thoroughly regulated or tested in the course of South-East Queensland municipalities potable water treatment and distribution. These contaminants are detrimental to experimental / laboratory processes that require precision, high sensitivity and precise instrumental operation.

Boonal Joint Venture - Coal Load Facility Dewatering Pump

Details:

Our SOLUTION:

Water purification is highly dependent upon local (and even site-specific) variations in the make-up of the town / tap water quality, which can differ greatly from place to place. For this reason Dowdens Engineers have designed each and every SNP high purity water treatment system individually, with local and site specific feed water characteristics in mind. The most recent system was installed at SNP's Central Laboratory located in Bowen Hills, QLD.

After careful analysis of the town water being delivered directly to SNP's Bowen Hills Laboratory a turn-key 'looped' treatment system was designed, manufactured and incorporated into SNP's existing Building Maintenance System (BMS). The first stage of this looped system is pre-treatment of the town water via a set of Duplex Carbon Filters and Water Softeners. The water is then fed through Duplex Matten Reverse Osmosis systems and Duplex 10" Deionisers and then stored in four 1,000L loop tanks. This treated water then passes through a set of four Deioniser Polishing Systems which (via a pump) is recirculated into and around the labs as 18 MΩ/cm ultrapure water (UPW).

This 'looped' high purity water treatment system delivers 56,000L of 18 MΩ/cm UPW / day - providing not only the capacity required for SNP's entire Bowen Hills Central Laboratory, but also delivering sufficient redundancy so that during times of service / maintenance the lab and testing machines are never without sufficient UPW to remain operational.

Dowdens Pumping - Brisbane's design philosophy for this project was: Cost Effectiveness - Ease of Installation - Simple & Reliable Plant Operation - System Reliability & Reduction of Ongoing Maintenance Costs. The entire SNP high purity water treatment system was designed, manufactured, installed and commissioned on time and within budget.

Specialised Pontoon Pumping System

Case Study

Customer: Peabody Energy Australia

Location: Moorvale Coal Mine, QLD

Specifications & Features:

Peabody Energy - Australia

Peabody Energy Australia have engaged Dowdens Pumping & Water Treatment's [Mackay] Engineering Department & Fabrication Workshop to deliver a Specialised Pontoon Pumping System for use at their Moorvale Coal Mine, located 156 kilometres South West of Mackay, QLD. This project presented a number of challenges for the Dowdens Mackay engineering and fabrication staff, including but not limited to an extremely tight delivery timeline of only 8 weeks!

Peabody Energy's Moorvale Mine is an open-cut coal mine that produces low-volatile pulverized coal injection (PCI) coal, coking coal and thermal coal for export markets. The Moorvale Coal Mine is particularly challenging for its operators due to the coal seam being quite narrow with a number of fault lines. This requires excavators often having to work in confined areas. The three piles that make up the Moorvale coal seams are mined independently of each other.

Dowdens Specialised Pontoon Pumping System was needed to provide Peabody Energy more reliable access to good quality Raw Water from an on-site dam. This raw dam water was then to be pumped directly to the onsite Coal Handling & Preparation Plant (CHPP). The existing supply water was limited and of poor quality. Dowdens new pontoon pumping system allowed for an increased volume of water to be pumped from a dam containing higher quality raw water. Subsequently the Specialised Pontoon Pumping System that Dowdens supplied has helped facilitate an improvement in the CHPP's daily operations.

"This particular project had a tight lead & build delivery timeline (approximately 8 weeks). During this time Dowdens were in regular contact with us, the project coordination and regular contact I received from Dowdens Engineers enabled me to better plan for the delivery and installation of the gangway and pontoon, which required a 100 tonne crane to be booked and ready onsite for the unloading and installation.

Dowdens Engineering Department was prompt and professional in helping resolve revisions in the project scope. The design and the way the pontoon was packaged and delivered added to the "Zero Incidents" achievement during the installation of the Pontoon on site. I was satisfied with the product, price and customer service provided by Dowdens Pumping & Water Treatment - Mackay"

Dowdens Pumping & Water Treatment - Specialised Pontoon Pumping System [Moorvale Coal Mine, QLD]

Details:

This project required both Dowdens Engineering Dept. & Fabrication Teams to deliver an innovative solution not previously attempted in-house. It was the first time Dowdens had manufactured 12m length gangways or a pontoon with a total weight of over 6 tonne. The total pontoon weight includes all steel work, flooring, pumps, piping etc. and is displaced using HDPE (high density polyethylene) Floats. The longest gangway Dowdens had supplied previously measured 8m in length, with the largest pontoon previously fabricated weighing in at 4.5 tonnes.

The new system meant Dowdens existing in-house designs had to be modified / improved with new floats being selected in order to safely carry the increased platform weight. Additional weight saving measures were implemented by Dowdens Engineers such as the use of light weight / high strength aluminium mesh flooring.

The timeline to design this pontoon pumping solution, manufacture the components and have them delivered to site was extremely tight. Engineering - Concept Design - Drawings & In-House Fabrication of the unique Pontoon Pumping System was completed & delivered to Moorvale Mine within their specified 8 week time frame!

No other pumping / manufacturing / engineering firm in Queensland are able to deliver such an all-encompassing product solution within the above mentioned time-frame.

Dowdens design philosophy for this project was: Fast Turnaround - Cost Effectiveness - Ease of Installation - Simple Plant Operation - Plant Reliability & Reduced Maintenance.

Coppabella Township Water Treatment Plant

Case Study

Customer: Aurizon Holdings Limited

Location: Coppabella, QLD

Specifications & Features:

Aurizon Holdings Limited

Aurizon Holdings Limited have engaged Dowdens Pumping & Water Treatment [Mackay & Brisbane Branches] to deliver a Water Treatment Plant (WTP) at their Coppabella Township, located on the Goonyella Rail Corridor (the world's largest metallurgical coal rail system) - 159 kilometres South West of Mackay, QLD.

The township of Coppabella was primarily designed and built to service the junction of two railway lines (one from Goonyella Coal Mine and one from Saraji Coal Mine) and to provide accommodation to the regions coal mine workers in work depots. The town was established in three stages, with the first being completed in 1971, the second in 1977 and the third and final stage in 1984. The town is wholly owned and operated by Aurizon Holdings Limited and contains: stations, residences, single-quarters, work depots, hotel, a shop, swimming pool, football oval, caravan park, school, ambulance, fire brigade and of course the new Dowdens Water Treatment Plant which is capable of producing of up to 900kL of potable water per day.

Dowdens engineers and service crews designed, manufactured, installed and commissioned the Coppabella WTP to treat raw water to Australian Drinking Water Standards. As the Principal Contractor Dowdens were provided a set of feed supply water parameters coming into the WTP, and water quality requirements for the delivery of the town's drinking water. From these basics the $2.5 million project came to fruition. The Dowdens WTP replaced the existing water softening plant (located adjacent to the new WTP), whilst future-proofing the growth of the Coppabella township by increasing the WTP's maximum daily drinking water production capacity up to 900 kL/day.

The new WTP is completely automated and user adjustable via the GE Human Machine Interface (HMI) situated in the purpose built site Control Room / Office, minimising the need for direct operator interaction / intervention on-site. A dedicated remote monitoring / alert messaging system was also provided so that in the event of a critical alarm the EDAC 700 RTU will call the WTP Operators advising them of system alarm status via pre-recorded spoken messages.

Security of the WTP site was significantly improved with the establishment of a controlled compound restricting access to authorised personnel only (pictured below). Dowdens also eliminated the need for repetitive manual handling of typical WTP chemical consumables on-site (Salt, Liquid Chlorine and Soda Ash) via the integration of various bulk storage systems.

Dowdens Pumping & Water Treatment Coppabella Township Water Treatment Plant [Coppabella, QLD]

Details:

Dowdens were successful in the tendering process due to:

  • The proximity of Dowdens head office [Mackay] and ongoing presence in the region
  • Dowdens vast in-house engineering capabilities and proven competencies
  • High level of detail provided in the preliminary engineering proposal
  • Proposed Water Treatment Plants cost effectiveness

Dowdens coordinated the design, build and commissioning of the WTP from project inception through to final handover. This included, but was not limited to: preliminary design - detailed design - risk assessments (with client and consulting engineers) - preliminary civil works establishing the site (levelling site) - under boring Peak Downs Hwy for installation of raw water pipeline - installation of all underground services - pouring of slabs - construction of the Ion Exchange (IX) building - installation of process equipment - installation of all interconnecting pipework - electrical installation of control panel and field instrumentation / equipment - commissioning of instruments / equipment - commissioning of PLC program and HMI - successful completion of 'Proof of Performance' testing and all necessary operator training.

The inclusion of a unique Brine generation system was a novel approach that incorporated a salt bulk bag unloader (capable of lifting 1200kg bags - pictured below) and a proprietary piece of equipment from the USA [BRINE ExtremePro]. The IX system is flexible in its design and is capable of producing between 150 - 900 kL/day of potable water with the IX system constantly analysing and compensating for variations of incoming bore water hardness levels.

The existing water softening plant (located adjacent to the new WTP) and raw water supply needed to be retained during the new WTP construction. The old plant was decommissioned over a period of 3 months. Nearing project completion a wet weather event (February 2016) resulted in additional water flows through the WTP site causing some minor displacement / erosion of soil and stone that required a brief plant shutdown to rectify the damage. Dowdens performed this work efficiently and effectively eliminating any risk to the township's drinking water supply.

Dowdens Pumping & Water Treatment design philosophy for this project was: Cost Effectiveness - Current Best Practice - Ease of Installation - Simple & Effective Plant Operation - Plant Reliability & Reduced Ongoing Maintenance.

35 bar Pressure Reducing Valve Station

Case Study

Customer: Anglo American - Moranbah North Coal Mine

Location: Moranbah, QLD

Specifications & Features:

Anglo American Moranbah North Coal Mine

Dowdens Pumping & Water Treatment's Mackay branch were engaged by longstanding customer Anglo American (Moranbah North Coal Mine Site) to deliver an innovative valve system that could help maintain the safe and reliable delivery of general purpose & fire water services to their ever-expanding underground mining operations. With growing demand for reliable water flow & pressures at ever-increasing operating depths, Dowdens decided it was time to design & produce a new generation 35 bar Dual Pressure Control Station, expanding our range of standardised pressure reducing valve stations.

Dowdens Pumping & Water Treatment fabricate and fit out a range of standardised pressure reducing valve stations, but this station required a higher pressure rating not available with our standard 'off the shelf' systems that are available in 16 / 25 bar (35 / 40 bar rated systems are built to order). Dowdens have manufactured these products for many years to help our resource industry customers arrest any water pressure spikes and/or surges in pipe systems and to aid these mines operating within and remaining fully complaint with Queensland Government Mine Site Compliance legislation, standards & guidelines.

This new Dual Pressure Control Station has been built to optimise plant reaction speeds, allow for greater operating ranges from between 2 - 35 bar and is manufactured with high-quality, reliable and readily available components. The design needs for the new Dual Pressure Control Station were borne primarily from Dowdens detailed underground observations of hydraulic occurrences within the mines existing water network. Working closely with the mines water infrastructure operators Dowdens were able to engineer, manufacture and deliver a product that increased the reliability of their mine water supply systems and assist with premeditated preventative maintenance routines.

All design, fabrication, installation & commissioning of the 35 bar Pressure Reducing Valve Station was undertaken by Dowdens Mackay's in-house Engineering, Fabrication & Workshop Departments. With a history of successful installations over the past 20 years throughout the Queensland Mining Sector Dowdens Pumping & Water Treatment have the ability to expertly design / manufacture / install and commission specialised pumping and water treatment solutions that are built primarily in-house & onsite to our client's specific unique requirements. Dowdens dedicated departments of industry trained engineers, draftsmen, project managers, sales staff and tradespeople including fitters, mechanics, polywelders, machinists, plumbers, electricians and boiler makers enable us to offer an unmatched range of world-class engineering solutions for any type of fluid handling project. We truly are Queensland's premier 'one-stop-shop' for pumping and water treatment systems!

Moranbah North Coal Mine - 35 bar Pressure Reducing Valve Station

Details:

At this projects inception Dowdens visited site to examine and document the specific operating requirements. After initial observations it was concluded that a wider operating range would be required for effective control of both the High and Low Flow demands and a higher adjustment range - meaning the standard Dowdens 25 bar Pressure Reducing Valve Station needed to be modified to suit this application. This higher pressure is not normally encountered with Queensland underground mine water supply systems so unique and customised hydraulic control layouts, pilots & hardware were seamlessly incorporated into the build by the Dowdens Mackay Workshop and Project Engineers.

This projects entire design, manufacture, installation & commissioning process was completed on budget and within a tight timeline of 4 weeks set by the customer.
