Solid Liquid Separator in Waste Water Treatment Dissolved Air Flotation(DAF) Units for Industry Wastewater Treatment


Product Description

Process water is needed in many production processes as a solvent, for production of material, or for cleaning purposes. Water is recirculated and reused 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. 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. Various types of flotation processes have been developed, whereof dissolved air flotation with pressure water recirculation has proven most effective.

The Benenv dissolved air flotation Plant provides a significantly improved flotation process with a special inlet structure that provides optimum control of the flow within the flotation tank.

Benenv dissolved air flotation has several advantages:

Completely made of stainless steel

With optional chemical treatment stage - increased separation efficiency

Standardized sizes for different applications

Compact , small footprint

Simple pressure release principle by means of a single valve for maximum operating reliability

Efficient, gentle mixing of the air bubbles into the wastewater flow

Defined tank flow due to the optimal of the blending and feeder construction in the flotation tank

Large effective clarifier area due to the lamella separator, minimized risk of blocking due to suitably dimensioned gaps between the lamella plates

Generation of saturated pressure water with a multi-stage pump which is not subject to the pressure tank regulation

Experience from hundreds of installations in a variety of fields of application
