In March 2018, the remediation of the Lagoon in Thermi was initiated for the second consecutive year. Alphabio applied the bioaugmentation method with the controlled dosing of BIO-M product, while auditing lagoon’s remediation progress. The main targets of the application were the reduction of pollution load and turbidity, and the improvement of water clarity. COD, BOD, TSS and turbidity values were decreased by 53, 89, 68, and 65%, respectively. The overall improvement in water clarity was also quite obvious.
