Maintenance of aerobic septic systems
There are two types of systems for aerobic wastewater treatment:
- Aerated wastewater treatment systems (AWTS)
- Aerobic sand filters
What is an AWTS?
An AWTS is designed to treat wastewater to a level suitable for surface irrigation within the site. Following primary treatment, the effluent is treated by a process of aeration, settling and disinfection and then pumped to a dedicated irrigation area as recycled water.
What is a sand filter?
Sand filters achieve a similar result to AWTS but the treatment process is different. The effluent from a septic tank is filtered through a sand layer which provides natural aeration and biological oxidation through aerobic and nitrifying organisms. From the disinfection chamber the recycled water is pumped to the dedicated irrigation area.
Servicing
AWTS and sand filters must be serviced by an appropriately trained person at specified intervals as recommended by the manufacturer in the service manual.
