Daf Plant Water Treatment

Low cost fully automatic self cleaning system.

Daf plant water treatment.

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. 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. Dissolved air flotation system. While many industries use this system the daf wastewater treatment system was designed to remove three main types of contaminants from a wastewater stream.

Dissolved air flotation or daf is a highly popular wastewater treatment process used by many water intensive industries such as oil refineries petrochemical and chemical plants natural gas processing plants paper mills food and beverage industry general water treatment and similar industrial facilities in order to reduce pollutant loads in wastewater streams by removing suspended solids. Designed by biocell water experts in sewage treatment. 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. 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.

Daf water treatment how does it work. The system is used for the reduction of chemical oxygen demand cod present in fat grease oil colour organic matter biological sludges and. The removal of suspended solids is often the focus of municipalities that implement. The released air forms tiny bubbles which adhere to the suspended matter.

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. Dissolved air flotation daf is a proven and effective physical chemical technology for treating a variety of industrial and municipal process and wastewater streams. Fully assembled and factory tested. The purpose of daf.

Dissolved air flotation daf is a water treatment process for removing oils solids and greases from a water supply. Various types of flotation processes have been developed whereof dissolved air flotation with pressure water recirculation has proven most effective. The process helps clarify wastewaters by eliminating different types of suspended matter. 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.

Daf dissolves air in pressurized water then releases it at atmospheric pressure. Operates without mechanical scrapers. These types are suspended solids biochemical oxygen demand and oils and greases.
