Daf Water Treatment Video

Water tecnik daf systems introduce incoming effluent into the daf tank in a flow through manner wastewater comes in one side and goes out the other.

The coagulants used most often in water treatment are aluminum and ferric salts. Once saturated the recycle is introduced into the daf inlet reaction chamber where it co mingles with raw incoming wastewater. Coagulation is a chemical addition step. Dissolved air flotation daf 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 dissolves air in pressurized water then releases it at atmospheric pressure. Daf systems are commonly used for the removal of oils greases and suspended solids to meet a variety of treatment goals including. Dissolved air flotation daf is a proven and effective physical chemical technology for treating a variety of industrial and municipal process and wastewater streams. While many daf units push sludge across the entire length of the tank in the same direction as the wastewater flow water tecnik use a skimmer assembly that rotates against the hydraulic flow of the effluent.

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 city of waco s new dissolved air flotation water treatment plan provides the ability to effectively remove taste and odor while reducing the use of expensive treatment chemicals. The air pressure then dissolves air into the water to become saturated recycle. Pewe s daf water treatment systems perform an effective wastewater clarification process that results in the removal of more material than traditional means.

Figure 1 is a process schematic diagram for a daf drinking water plant. 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. Coagulation and flocculation are required pretreatment processes. 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 effluent end pump and pressurize it into the rad pressure vessel where it is subject to compressed air pressure. Come along for a tour of the city s dissolved air floatation water treatment plant and find out why this facility is necessary.
