Dowdens Pumping & Water Treatment secure rights to MIRACELL Sewage Treatment Systems

Monday, 1 December 2014

Dowdens Pumping & Water Treatment are proud to announce securing Australia-wide exclusivity of the MIRACELL Rotating Biological Contactors (RBCs) Sewage Treatment Systems. MIRACELL RBCs are the systems are most preferred globally by customers who clearly understand the economic value in purchasing an expertly designed and professionally built Sewage Treatment System!

MIRACELL RBC Sewage Treatment Systems are fully automatic, modular designed Rotating Biological Contactor (RBC) treatment systems specifically designed for sewage treatment applications in capacities ranging from 50 to 20,000 equivalent people (treatment of between 10m3 up to 4000m3 / day). Representing the ultimate in Sewage Treatment Systems, a MIRACELL RBC consumes as little as one fifth of the electricity and requires as little as one third of the space of its competitors based on the activated sludge technology.

Having exclusive rights to MIRACELL RBCs has increased Dowdens capacity to design, supply, install and service large scale Sewage Treatment Systems suitable for use by municipalities, caravan parks, mining camps and a wide range of other commercial / industrial sites where onsite sewage treatment is needed.

Dowdens Pumping & Water Treatment employs an experienced team of WTP and STP Project Specialists comprising of Mechanical and Process Engineers, Project Managers, Draftsmen with 3D Autocad skills and qualified installation and service crews, together with our in-house workshop facilities for the fabrication of steel and stainless steel skids and bases, Dowdens has little to nil reliance on outside contractors when delivering complex Water and Sewage Treatment systems - in essence we are a 'one-stop pumping, water and sewage treatment shop'.

Whitsunday Gardens Caprari-CPC Pump Station

Case Study

Customer: Relag Group Pty Ltd

Location: Proserpine, QLD

Specifications & Features:

Whitsunday Gardens Estate situated in Proserpine, QLD is a new land release subdivision located just 25 minutes from the iconic Airlie Beach.

Relag Group Pty Ltd are responsible for this new urban housing development and subsequently engaged Dowdens Pumping & Water Treatment [Proserpine branch] to design, supply and install a Precast Concrete Pump Station for use in Stage 3 of the Whitsunday Gardens Estate subdivision development.

Stage 3 of the subdivision development required a standalone sewage pump station to be installed capable of handling the residential waste water and sewerage borne from 20 subdivided lots. The land was used to farm sugarcane before the development began in 2013.

Whitsunday Regional Council Water and Sewage Executive ManagersBefore the design and construction phases could begin Dowdens met extensively with the Whitsunday Regional Council's Water & Sewage Executive Managers to discuss the suitability of the Caprari-CPC Sewage Pump Station, the design peculiarities required for the working in the region (a high water table onsite) and how Dowdens could adapt the Caprari-CPC system to best suit the site requirements.

Multiple options were presented in the initial design drawings helping to satisfy Whitsunday Regional Council (WRC) specifications; including locally designed and engineered aluminium access covers requested by the WRC [ensuring uniformity with all other waste water assets held in the region], inhouse manufacturing of specific handrails to meet municipal safety codes and working with WRC's preferred switchboard manufacturer [Belmont Electrical].

During the initial project scoping Relag Group Pty Ltd reviewed three options for their sewage pump station system: pre-fabricated fibreglass, mould formed precast concrete and concrete pour in situ. The Dowdens Caprari-CPC Sewage Pump Station won the selection process due to the following product benefits:

Project engineering consultant (Trevor Glasson) utilised the dedicated Caprari-CPC Selection software to assist matching the correct system layout to the site specifications. Caprari-CPC Selection software allows registered members to generate an integrated design solution for the selection of an appropriate chamber, pumps and mechanical components for specific applications. The integrated design solution includes: GA Drawings of the chamber along with a "CAD Kit" providing all CAD elements to enable rapid transformation of the GA drawing into a full production drawing; Full component listings, including mechanical specification for your customised fit out; System curve, total system duty, pump recommendations and a budgetary quote is available on request.

Trevor was able to design the system and submit that to WRC for approval. Once selected the Caprari-CPC Pump Station was installed, commissioned and the whole projected managed by Dowdens Pumping & Water Treatment [Proserpine branch].

Longwall Boost Pump Station

Case Study

Customer: Anglo American - Australia

Location: Moranbah North Coal Mine - Moranbah, QLD

Specifications & Features:

Dowdens Pumping and Water Treatment was engaged by Anglo American Moranbah North Coal Mine to design, engineer and build a boost pump station to supply raw water to the longwall area.

Dowdens Pumping and Water Treatment designed and built the longwall boost pump station utilising dual variable speed pumps to enable the station to cater for varying duties as the underground workings progress further away from the station.

Anglo American's Moranbah North coal mine began operation in 1998 and currently supplies 4.5m tonne annually of high fluidity premium hard coking coal mainly for export to iron and steel manufacturers in Japan, Korea and Taiwan.

The pump station boosts water pressure to the longwall currently some 6,000m away.

Comprehensive 'pre-challenge' testing was completed prior to the station being transported to site, with all parameters being set during this time.

Dowdens team of specialised engineers, CAD draftsmen and tradespeople were able to design and build the station on time and to a tight budget, with Anglo American extremely happy with the work undertaken and product supplied.

Testimonial: Anglo American - Australia (Moranbah North Coal Mine) reported "The longwall booster pump station was taken underground into immediate service after only a couple of days. There is normally a one or two month delay with above ground commissioning for all new units. Since the pump powered up after the first run it has not stopped running and is sitting at only 10% duty. The longwall has cut 128,000 tonnes so far which is exceptional. Any future boost pump orders from Dowdens Pumping and Water Treatment will not require any changes to the design or manufacture."

Key Pump Station Features:

  • KROHNE flow meter
  • Pump station utilises four pressure transducers to feed real time pumping data to the computer control
  • Two vertical stage pumps directly coupled to two 45kW motors
  • As the booster pump station was dealing with high pressures all piping and flanges have a 3,000kPa rating
  • Pump station fitted with QDS (Quick Detachment System) lift points - allowing the station to be transferable via the underground Line Eimco
  • Touch screen interface enables underground miners access to real time amperage, bearing temperature and flow rate data
  • The unit operates via a PLC (Programmable Logic Controller) and SCADA (Supervisory Control and Data Acquisition) system meaning it can be remotely operated from the mine control room on the surface, or underground via the unit's electronic controls

Total Water Volume Transfer: 30L/sec @ 80m head (currently)
