Daf Plant Water Treatment

Dissolved air flotation daf is a water treatment process that clarifies wastewaters or other waters by the removal of suspended matter such as oil or solids.

Daf plant water treatment.

Designed by biocell water experts in sewage treatment. Fully assembled and factory tested. Daf water treatment how does it work. Dissolved air flotation daf is a proven and effective physical chemical technology for treating a variety of industrial and municipal process and wastewater streams.

Daf sewage treatment plant for food process effluent factory effluent and industrial wastewater. In many of these applications the removal of any cod associated with the solids removed is also a key benefit aiding compliance with discharge consents helping to reduce mogden charges and or reducing biological load on downstream processes. Daf dissolves air in pressurized water then releases it at atmospheric pressure. Daf is an alternative clarification process that uses micro air bubbles to attach and float flocculated particles and suspended solids to the water surface for removal see fig.

Various types of flotation processes have been developed whereof dissolved air flotation with pressure water recirculation has proven most effective. Dissolved air flotation daf is a water treatment process for removing oils solids and greases from a water supply. The released air forms tiny bubbles which adhere to the suspended matter. The removal of suspended solids is often the focus of municipalities that implement.

Operates without mechanical scrapers. The purpose of daf. Dissolved air flotation system. Low cost fully automatic self cleaning system.

These types are suspended solids biochemical oxygen demand and oils and greases. The daf water treatment process clarifies wastewater and is typically used in a wide range of industrial applications to maintain environmental compliance and mitigate the financial impact of trade effluent charges. While many industries use this system the daf wastewater treatment system was designed to remove three main types of contaminants from a wastewater stream. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.

The system is used for the reduction of chemical oxygen demand cod present in fat grease oil colour organic matter biological sludges and. The huber 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. Since 2000 more than 50 drinking water treatment plants wtp in north america have used daf with capacities ranging from 0 5 mgd to 290 mgd.
