How to select a Sewerage Treatment Plant

Sewerage treatment is the process in which sewage is cleaned by biological and chemical processes in order to remove contaminants. It can then be re-used as farm fertilizer or disposed of. Selecting a sewerage treatment plant can be a lengthy process but with proper knowledge and research can be simple. There is a sewerage treatment plant in nearly every large city and close to smaller ones. Urban areas will have more of a need for a large plant due to the amount of waste coming in. A good example of a high quality sewerage treatment plant is Athena Water Services. They are a leading Australian water treatment company that supplies wastewater treatment plants and potable and non-potable water treatment plants.

Athena Water Services

Athena Water Services targets commercial sewerage treatment systems. Their treated effluent water meets proper standards for compliance and can be re-used in many different applications.

Some of these include:

  • Wash down water
  • Dust Suppression
  • Industrial Use
  • Limited use in multi dwellings

Their treatment plants meet the minimum EPA guidelines for environmental discharge and they treat their effluent water to Class A classification standards. Microbes are used for decomposing dead materials before returning them to the environment. They require moisture, oxygen, temperature and waste to convert into energy and are used in any sewerage treatment process. Athena’s standard sewerage treatment consists of three stages.

These stages are:

  • The anaerobic stage
  • The aerobic stage
  • Filtration stage

The anaerobic stage allows for the effluent water to begin breaking down. It is here that the water accumulates before beginning the process. In the aerobic stage, air is added to stimulate the microbe activity. The microbes are usually added in the form of a solution in order to stimulate breakdown of the effluent. This also keeps undigested sludge to a minimum. Finally, in the third stage, the remaining cleaned water is filtered before re-use. Their aerobic process uses a system called the Biocleaner system, which uses natural power to treat different kinds of organic waste and produces its own microbes.

Selecting a sewerage treatment plant should be easy if some things are taken into consideration. The plant should comply with EPA and local standards. It should properly treat sewage and use the correct processes when treating effluent in order to minimize impact on the environment as well as be re-used as fertilizer or some other type of environmentally friendly or useful material.
