Aerated Wastewater Treatment System (AWTS)
An AWTS consists of one or two wastewater tanks, which contain a series of chambers. Wastewater enters the primary chamber where solids settle to the both to form a sludge layer. The scum layer, containing fats and greases, collects at the top of the chamber. The clarified wastewater flows from between the two layers to the aeration chamber. In the aeration chamber, the wastewater is aerated and broken down further by biological activity. The wastewater then passes through to the settlement chamber where any solids that may still be present are separated/settled. The wastewater is finally disinfected in a chlorination or UV chamber and irrigated through fixed wastewater hoses across lawns or gardens either via a surface or drip irrigation system.
AWTS must be regularly serviced and maintained as per their specifications in order to operate correctly.
