Treatment Plants - Biological purification through prolonged aeration without anoxic chamber
DINOTEC’s DOÑANA N modules are made of GRP through the 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. It is a solution for treating wastewater in populations of up to 1,000 inhabitants.
DOÑANA N reactors include all the necessary operations for a secondary biological treatment. They replace aeration tanks and traditional settlers and reach a high performance while maintaining low energy, space and volume requirements.
