Dissolved air flotation food industry wastewater wastewater treatment plant municipal wastewater flotation system wastewater treatment
Flotators UF device is intended primarily for pre-treatment of concentrated food industry wastewater. With outstanding results is operated in meat factories, slaughterhouses, poultry plants, dairies and other productions of the food industry and in other industries such as paper and plastic recycling, or in oily municipal wastewater.
Flotation significantly reduces mainly extractable contamination (fats), also important are indicators of organic pollution reduction BOD5 and COD. Flotator is usually preceded by a rotary screen as the first stage of treatment (removes from the water flowing into the flotator coarse, insoluble impurities - such as parts of bones, skin, bristles, glass, paper, etc.).
Another application of flotation is in thickening of excess sludge from municipal wastewater treatment plants, which is called DAFT (Dissolved air flotation Thickening). Without dosage of flocculant is a sludge with input concentrations 0.6-1% concentrated by flotation to 4-5%.
Our packaged DAF plants are pre-assembled and pre-tested in our controlled facility, often saving 50 percent or more over in-situ construction. They can also be integrated into pre-engineered building systems for increased savings and reduced schedule. Their small footprint also reduces building costs. Simplicity Our DAF plants are quiet, simple and easy-to-operate with minimal operator input. They are also supplied complete with chemical dosing, water quality instrumentation, automatic controls and monitoring systems customized to meet local needs.
