How the Oasis Clearwater Series 2000 septic tank works:

oasis series septic tank
  1. Wastewater initially goes through two settlement chambers.
  2. Then water will flow into a high performance filter (Zabel A300) in the central aeration chamber where further biological and mechanical filtration will occur.
  3. During this process thousands of tiny air bubbles are created by the series 2000 fine air diffuser assembly.
  4. The contents of the filter are mixed at a constant rate providing essential oxygen for the aerobic digestion and cleansing process.
  5. This process will continue as water flows through until it is finally moved to the outflow chamber.

Through a process of filtration, settling and aerobic digestion it quickly and efficiently turns household waste water into high quality irrigation water.
