Experimentation in the sludge line
Aquasoil srl, in association with Innoven srl and Novus srl, has won the tender for the award of a pre-commercial contract (ex art.19 co.1 lett.f of Legislative Decree nr. 163/2006) concerning industrial research and experimental development services for the creation of a new system to reduce production to a minimum, improve quality and encourage the reuse of sludge in the treatment and purification processes of urban waste-water.
The following steps were taken:
to intervene in the water line, producing the maximum amount of primary sludge, improving the quality of water sent to biological treatments, through the controlled dosage of a polymeric coagulant and any other reagents both in solid, liquid or gas state;
to reduce secondary sludge;
to optimise the anaerobic treatment of sludge, with the maximum production of biogas and the consequent reduction of the quantity of sludge by the thrust dehydration of the same.
