CAP Treatment Plant-how it works Watch Here
The Harlequin CAP sewage treatment Plant has been designed to treat domestic sewage in three stages, Primary settlement, biological filtration and final settlement
Stage 1. Primary settlement: Wastewater enters the system to primary chamber, where settlement takes place with heavy solids settling to the bottom and retained in this chamber. Anaerobic bacteria break down organic matter in this chamber with clarified water passing to the next stage
Stage 2. Biological Filtration: Clarified water enters the aeration chamber. In this chamber the free moving plastic media which provides a large surface area on which the bacteria required for the purification process can grow, combined with continuous aeration provide oxygen to nourish the bacteria. The continuous aeration for the process is supplied by a remote diaphragm blower (situated outside the tank) and fine bubble diffuser situated at the base of the tank.
Stage 3. Final Settlement: The treated water from chamber 2 flows into this smaller settlement chamber, where any sludge settles and is recirculated back to the primary settlement chamber. The completely treated water is then discharged either by gravity or pumped to a soakaway system or watercourse as permitted.
