In each any technology, processing system is done through the process. With each step, the waste water, sludge and treatment chemicals will be different, so each stage will have dedicated pumps are used to ensure the system to achieve optimal performance.

1. Sewage transportation before and after treatment: centrifugal pumps, submersible pumps

2. Transportation chemical, chemical feed: Centrifugal pump, dosing pump

3. Sludge transport, and sludge treatment: Screw pumps, centrifugal pumps, compressed air pumps

4. Gas supply system: Low-pressure screw blower

5. Mixing tank: mixer
