WASH BAY WASTEWATER RECYCLING FOR CONSTRUCTION EQUIPMENT DEPOT

BACKGROUND

As part of a facility upgrade, Hastings Deering required a new wash bay water recycling system at its Rockhampton facility.

The wash down water was largely contaminated with dirt and soil, but there were was also a small amount of oil and grease entrained in the wash down water that needed to be removed prior to re-use.  Bench testing demonstrated that Dissolved Air Flotation (DAF) was the lowest cost solution.

SOLUTION

MAK Water was selected to design, manufacture, install and commission a wash bay water recycling system, working in partnership with Hastings Deering and their Project Engineers.

Dissolved Air FloTation (DAF)

• A recycling system capable of treating 10,000L per hour of wash down water
• Hydroxide precipitation, flocculation and DAF clarification removes silt, heavy metals, seeds, weeds and pests from the water
• Filters and disinfects the water to ensure it meets safe water and occupational health and safety requirements to reuse for vehicle and equipment wash down
• Supply and onsite installation of interconnecting pipework and electrical
• Fast 10-12 week delivery time
• Onsite commissioning and training of local operators, with ongoing service and maintenance agreement

RESULTS AND BENEFITS

• Lowest total operating cost. Eliminated the use of potable water for wash down and the need to discharge contaminated water to the local sewer.
• Compliance. Compliance with planning and regulatory requirements.
