DINOTEC’s MULHACEN DCS modules are made of polypropylene through thermowelding of plates and has a horizontal, prismatic shape. Polypropylene is a recyclable, non-toxic material that has a high chemical and structural resistance.

MULHACEN DCS module is an activated sludges reactor with a pretty low mass load formed by two different chambers:

• One chamber of aeration, where oxidation of biodegradable organic matter takes place through absorption or synthesis of activated sludges. The supply of O2 required by the sludges is reached through a deep air injection, ejector or blower pump, and diffusers that spread the air in small bubbles.


• Another settling chamber, where water clarification occurs as suspended sludges settle. Sludges deposited at the bottom are recirculated to the aeration vessel to maintain the microorganisms balance.

Compact modules MULHACEN DCS are used for treating the urban wastewater coming from populations from 250 to 500 inhabitants.
