 Overview
Waste water will not be a problem if its sources can use an efficient treatment system for recycling wastewater. For well-being in buildings and saving the environment over long term, on-site Aerobic Wastewater Treatment System (AWTS) employs high technology that would be the solutions for wastewater treatment.
The AWTS combined with anaerobic and aerobic biological process, sedimentation and disinfection in one system. It has been designed to replace the conventional septic or chemical toilet. Application and design criteria of the system varies from climates influent nature and practice in household.
Structure
Anaerobic Chamber
This chamber allows the storage of sludge and separate sediment and grease from the wastewater
by digesting organic matter and biodegradable organic using anaerobic bacteria. This process is slow
and requires long time for decomposition.
Aerobic Chamber
After the first chamber, the microorganisms in the contact media plate will digest organic matters.
Moreover, the aerator or diffuser will help to add oxygen to the tank for aerobic decomposition by
bacteria with high efficiency and to reduce undesirable odor. The diffuser has an air-disperation in a
backwash system. This aerobic process is fast for decomposition of organic wastes.
Sedimentation and Disinfection Chamber
This chamber will separate sediment after processing that comes with effluent to reduce BOD to the
standard. The sediment will be returned to the contact aeration chamber. Disinfection is achieved by
chlorination inside a small chamber. The water comes out without pathogenic organisms.
