In March 2018, the remediation of Lake of Thermi was initiated for the second consecutive year. Alpha Bioenergy took over the BIO-M product dosing and auditing of the progress of remediation of the lake. The main targets of the application was the reduction of polluting load, the improvement of water clarity and reduction of turbidity, while also the improvement of basic parameters of water quality (organic load, total suspended solids etc.). COD, BOD, TSS and turbidity values decreased by 53, 89, 68, and 65% respectively. The optical transition was also quite obvious.
