Efficient Wastewater Treatment with Dissolved Air Flotation
Meeting wastewater discharge requirements is essential for food and beverage manufacturers and wastewater treatment facilities. Dissolved air flotation technology enhances water clarity by removing suspended contaminants before downstream processing or discharge. FILTEC’s DAF systems efficiently separate solids and organic matter, reducing chemical usage and improving wastewater treatment performance.Â
Our DAF Solutions
Industrial Wastewater & Trade Waste Treatment
Industries like food & beverage, dairy, meat processing, and manufacturing produce high-strength wastewater that requires treatment before discharge. FILTEC’s modular DAF units remove suspended solids, fats, oils, and grease, ensuring compliance while managing fluctuating loads efficiently.Â
Sludge Thickening & Solids Separation
Wastewater treatment plants can optimise sludge management by using DAF technology to thicken biological or chemical sludge. This process reduces sludge volume, lowers disposal costs, and improves dewatering efficiency, making plant operations more cost-effective and sustainable.Â
Industrial Cooling & Boiler Feedwater Treatment
Cooling systems and boilers require high-quality feedwater to prevent fouling and scaling. FILTEC’s DAF systems remove suspended solids and organic contaminants, ensuring better water quality and protecting critical equipment, reducing maintenance needs and extending operational life.Â
How Dissolved Air Flotation Works
Dissolved Air Flotation (DAF) dissolves air into water under pressure and releases it into a flotation tank. As the pressure drops, microscopic air bubbles form and attach to suspended particles, lifting them to the surface. The floated solids are skimmed off, leaving behind treated water suitable for further processing or discharge. DAF systems are widely used for wastewater treatment in food, beverage and dairy manufacturing, requiring effective solids separation.Â
FAQs
What industries benefit from Dissolved Air Flotation?
DAF systems are widely used in food, dairy, meat, beverage and industrial wastewater treatment. They effectively remove fats, oils, grease, and solids from wastewater before discharge or further treatment.
How does a DAF system improve wastewater treatment efficiency?
DAF enhances separation efficiency by using microbubbles to lift suspended particles to the surface, reducing the load on downstream treatment processes and lowering sludge disposal costs.
What are the typical maintenance requirements for a DAF system?
Routine maintenance includes monitoring air saturation, inspecting skimmers, checking pumps, and ensuring the correct chemical dosing where needed. FILTEC offers servicing and support to maintain peak system performance.
Can a dissolved air flotation system reduce chemical usage?
Yes, DAF technology minimises the need for chemical coagulants and flocculants by enhancing the natural flotation of solids. This leads to cost savings and improved environmental outcomes.
How does a DAF system compare to other wastewater treatment methods?
DAF efficiently removes solids from wastewater with high fats, oils, and grease. More effective than sedimentation, it ensures high separation efficiency and is ideal for industries requiring superior water quality in a compact treatment system.
