The DFA C 800 T4 activated sludge purifier line offers an advanced and reliable solution for the secondary treatment of domestic or similar wastewater. These purifiers, made of monolithic polyethylene with a stiffened structure, guarantee high efficiency in the aerobic digestion of organic substances, reducing the production of excess sludge and facilitating maintenance.

The DFA C 800 T4 activated sludge purifier is designed to be buried and consists of a corrugated tank divided into two compartments: one for biological oxidation and the other for secondary sedimentation. Thanks to its configuration, the system ensures effective clarification of the outgoing sewage, which can then be discharged into the soil or sent for further treatment. The oxidation process takes place via membrane diffusers that introduce micro bubbles of air, powered by a membrane compressor, ensuring the supply of oxygen necessary for the microorganisms to decompose organic substances. The monolithic design of the product, with bayonet caps for cleaning and inspection, ensures durability and structural resistance, compliant with UNI EN 12566-3 standards and the requirements of Legislative Decree 152/06.
