Waste Water Treatment Presentation Done%by%Chris%Damen%
Contents • Typical example • Staring point and results before dosing • Summery of results week by week • Odour Control Technology • Overall Plant improvement
Starting point • The following results and images are a view of the typical condition of the WWT before we started dosing. • This specific plant was designed for 4 Mega Liters, and receives approx 7-8 Mega Liters per day. • Main concerns expressed by the WWT are typically: - Odour - Colour of the Clarifiers, and Aeration units and retention dams. - Non-compliant results of the outgoing effluent into the river
