Description
Dissolved air flotation Description
DAF is designed to mainly remove fats, oils and grease (FOG), suspended solids (TSS), parts of biological oxygen demand (BOD) and chemical oxygen dem and (COD) that hard to be dissolved in water and other pollutants from waste water. The process is simple - tiny bubbles attach to solid contaminants causing them to float and then sludge is skimmed off the surface of the water - but designing a DAF system for a real-world application isn't quite as simple.
Dissolved air flotation Feature
Flow rate of one set: 1-200 m³/h.
Recycling flow Dissolved air flotation.
High efficiency pressurization system providing high quantity dissolved-air water to create micro bubbles.
Custom design on different dissolved air flotation equipment and recycle flow ratio according to the type of wastewater treatment requirement to achieve target removal effect and stability.
Adjustable PP chain type skimmer to suit the different quantity of sludge.
Integrated coagulation flocculation tank and cleaning water tank(as optional)is available to save the space and cost.
Automatic and remote controllable.
Material of construction: carbon steel epoxy painted, carbon steel FRP line, SS304/SS316L.
