Aerobic Treatment Units

Department of Health WA-approved, Coerco's Aquarius® Wastewater Systems provide reliable wastewater treatment and recycling for domestic or resource and construction industries. Reuse treated water for irrigation, landscaping, orchards, and more, or safely disperse it into leach drains and soak wells.

Coerco Aerobic Treatment Units for Efficient Wastewater Treatment


Coerco offers a range of Aquarius® ATUs designed to effectively process wastewater in different industries such as resource, construction, commercial and residential sites. This treatment allows the recycled water to be safely used for irrigating garden beds, orchards, soak wells and or dispersals into leach drains, meeting the stringent standards of the Department of Health, WA.

Our O-2 NR and O-3 models go a step further by reducing phosphorous and nitrogen levels in the water, making them particularly beneficial for water catchment areas, environmentally sensitive zones, and in meeting local shire regulations. These models are recognised for their nutrient-retentive capabilities, which are crucial for environmental conservation.

Moreover, the Aquarius® O-3 stands out as our most eco-friendly option. It employs ozone in its final disinfection stage, even more effective than chlorine, leaving oxygen as its only bi-product.

Treatment Process

  O-3 O-2 NR O-2
Primary Tank
Retains the solid uses aerobic and anaerobic bacteria to breakdown the BOD5 levels in the sewage
     
Alum Tank
Doses the clarifying chamber of the treatment tank with alum. Alum acts as a flocculent to remove the nutrients and suspended solids and settle them to the bottom of the tank for further aerobic bacteria breakdown
     
Treatment Tank      
Secondary/Aeration Chamber
Incorporates aeration to further break down BOD5 and nitrates
     
Clarifying/Discharge Tank
The Clarifying Chamber provides a settling and clarifying period for the water prior to discharge
     
Discharge Chamber
The Discharge chamber contains the Discharge pump to pump the treated water out to irrigation or other disposal methods.
     
Ozonation Pump
Ozone is a powerful disinfectant, many times more effective than chlorine and kills bacteria.
