Where water is re-circulated for economical and environmental reasons, grease, oil, fat, floating and suspended solids, settling material, and dissolved components need to be separated to provide good and uniform water quality. Also recovery of valuable product from the water may be another additional objective. In addition, clogging and excessive wear of pipelines and other associated equipment is prevented, which increases the operating reliability of the production plant.
Where used process water is discharged as wastewater, pre-treatment is often required to prevent toxic or otherwise harmful substances from entering the sewer system and reduce thus surcharges and fees. Conventional gravity clarifiers are often incapable to achieve sufficient pre-treatment.
ASTiM Dissolved Air Flotation Unit “DAF” provides a significantly improved flotation process with pressure water recirculation has proven itself as most effective type of dissolved air flotation.
