Solid separation chamber is a septic tank to reduce suspension, heavy and light sediment mixed with sewage.

Aeration chamber is an air filler. It is a process of decomposition by air-based microorganisms. Inside the air filler, there is a medium (media) that increases the adhesion area to microorganisms in the system.

Sedimentation chamber is the sedimentation part. It acts as a microbial sedimentation from wastewater. Then wastewater flows through the chlorine disinfection chamber to disinfect before discharging water to the public rail or sewer.
