Gravity Clarification

Akuna Bay Marina in NSW required a treatment system to treat the waste stream from the Marina hardstand. The waste stream comprised general wash down of vessels during servicing and hull cleaning processes. The site has no access to a sewer for trade waste discharge, so wastewater treatment was required to enable treated wastewater to be discharged to the environment.

IPS Logistics installed a new un-roofed wash bay in compliance with the Department of Agriculture, Fisheries and Forestry’s (DAFF) guidelines, at its Port of Brisbane facility. The key objectives of the wash bay recycling system were to meet regulatory requirements and minimise the use of potable town water for wash down operations.

To help reduce the spread of weeds, a regional council in northern Queensland has built a wash down facility to help people remove weed seeds, soil and other foreign matter from their vehicles and machines. As potable water supply in the region is already under stress a key driver for this project was to recycle the wastewater created by the wash bay, so the council’s consultant engaged MAK Water to design and construct a suitable wash bay water recycling plant.

The first major road tunnel in Brisbane, The Clem Jones Tunnel (Clem7) is a 6.8 km toll tunnel that connects Brisbane’s inner north to the southern and eastern suburbs, bypassing the Brisbane CBD. Clem7 required a water treatment system to treat the groundwater from the tunnel, eliminating the need to discharge large volumes of water to the sewer or risk pollution of local waterways.

SuperCharge Batteries generates wastewater from the battery manufacturing process line. The wastewater needed to be treated to meet trade waste discharge requirements. This included heavy metal removal, pH adjustment and data logging of discharged effluent quality and volume.

MAK Water designed and installed a Gravity Clarifier System to a 2,000m2 marina wash bay in Victoria. The plant was commissioned and operational for several months, then developed complications to the discharge pit pumps, that send captured wash water into the MAK Water plant. Stones had begun to accumulate in the pit, consequently causing damage to the submergible pumps which required rebuilding.
