CAMUS

The raw sewage is screened through a fine screen and passed into an appropriately designed Tube Settler to remove all Organic and Inorganic particles less than 100 microns (rise velocity 1m/Hr) which results in a significant COD removal of . The clarified water is transferred into an EQT to handle the peak flow. Part of the EQT water is transferred to the nitrifying BM1 reactor which is typically 3m deep and around 250sqm/MLD (deeper beds occupy less space). The percolated water from BM1 is collected in CT1. Nitrified Water from CT1 and Ammoniacal water from EQT is mixed and percolated through BM2 typically 3m deep and around 250sqm/MLD where denitrification using COD from EQT water is undertaken. The final treated water is disinfected as required using Chlorination, UV, Ozone or other techniques. CAMUS process is a once-through plug flow process and does not require recycling to achieve BNR.  Note BioMedia in CAMUS process has to be carefully chosen granular porous media (50mm-100mm) either weathered rock or fired clay media certified by the technology providers. The granular porous media is regenerated via grazing over the surfaces  due to apex predators in this ecosystem: the Acarine Orbatid Soil Mites. The Sludge from the Tube Settler is automatically transferred to the Vermicomposting Bed (VCB) via pumps. The CAMUS process is therefore operable in the continuous mode.
