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. |

" We approached our plumbing supplier in Bunbury ,Macro Irrigation, looking for a tank to replace the existing one that had a split in the base of it, we had already had quotes but when we asked for 2 brass 80mm outlets in the tank we were told it could be done but cost a lot more and macro organized our tank from Coerco and the fitting were no issue done at the manufactures and the tank was delivered just as we ordered, the driver was helpful and friendly and also gave us some tips on ensuring the ground in our yard wasn’t going to damage the new tank. Will be looking at another purchase in the future and also recommend them as a supplier to our purchasing officers. "
