After the temporary storage for flow and load balancing, the wastewater is chemically conditioned. The type and dosage of chemicals depend on the wastewater content and requirements.

We usually do pilot tests. We add polymer for flocculation in all conditions. Chemically conditioned wastewater is treated in a Dissolved Air Flotation (DAF) unit.

Almost all oil and solids are removed as flotation sludge. The BOD and COD load is strongly reduced. DAF effluent can be discharged into sewers.

In cases where the wastewater will be discharged directly to the receiving environment or where it is recycled as process water, we carry out another treatment process for the wastewater.

We reduce the amount of activated sludge and flotation sludge from biological treatment with Sludge Densification and Sludge Dewatering machines.
