Treatment Plants - Biological purification through prolonged aeration without anoxic chamber
DINOTEC’s DOÑANA DCS modules are made of GRP through continuous winding of fiberglass-reinforced polyester threads, and have a horizontal, cylindrical shape. They are based on the biological process of extended aeration, which has the highest performance (more than 95 % in BOD5 and solids in suspension) and the lowest production of sludges.
DOÑANA DCS module is an activated sludges reactor with a small mass load formed by two different chambers:
Compact modules, DOÑANA DCS, are used to treat urban wastewater coming from populations between 350 and 600 inhabitants.
