Aqua Clarus treats selected greywater so it can be put to good use again. WCTNZ® helps businesses and property managers explore where recovered water could reduce demand on their usual water supply.
Toilet flushing, suitable washing-machine cold feed and irrigation all create opportunities to reuse treated water. For accommodation, shared facilities and managed developments, the opportunity starts with the greywater available and the demand it could meet.
The real benefit comes when there is a regular use for the water. We can help you compare what your property produces with what it could reuse, then look at equipment suited to the job.
The M800sx combines a biological trickle bed, 0.025-micron ultrafiltration and ultraviolet disinfection. Each stage takes care of a different part of the job, from breaking down organic material to fine filtration and disinfection.
Learn more about how Aqua Clarus works and its treatment quality and approvals.
The M800sx provides up to 800 litres per day of treated water available for reuse, depending on suitable source flow and operation. Its cabinet measures 1,100 mm wide × 720 mm deep × 1,800 mm high, with additional space for connections and servicing.
These figures describe the M800sx, whose published household rating is up to eight people. Larger and commercial projects need a configuration selected for their own loading, intended use and approval requirements.
WCTNZ® favours commercial-sized GreyFlow collection and filtration equipment to provide buffering before treatment. The Aqua Clarus cabinet transfers treated water into external storage, and a separate pressure pump supplies the reuse outlets.
We can explain the equipment options, prepare a package quote and talk through commissioning and ongoing servicing, so you know what is involved before you buy.
For non-drinking reuse. Kitchen and dishwasher flows may be included with suitable loading and grease/solids pretreatment. Toilet waste, toilet leachate, roof runoff, industrial process liquids and unselected wastewater remain separate.
Existing M800sx owners also have access to product and care guidance. Keep the manufacturer’s manuals, WCTNZ supplement and installation records together for future servicing.
Tell us about your property and how you would like to reuse water. A simple plan or a few photographs will help us start the discussion.
