Dissolved Air Flotation System

High Efficient Sedimentation DAF System

High Efficient Sedimentation DAF System has thoese main features: 1.Inclined plates installed can enhance the separation efficiency 2.Full coverage skimmer design 3.Suitable for high concentration solids 4.Design hydraulic loading rate:5-12m3/m2/h 5.Disadvantage is higher porice than other series

Introduction

High efficient sedimentation DAF System has been known and applied widly as one of the most effective and economic ways to remove suspended solids (SS),fats, oils and grease (FOG), phosphorus (P) from industrial wastewaters by the generation of micro bubbles.
Jorsun DAF is an innovation combined with traditional high efficiency sedimentation dissolved air flotation design theory and modern technology after years of research and application.DAF is based on a physical / chemical process.Wastewater is dosed with treatment chemicals upstream of the DAF inlet to form flocs.

When those flocs enter to the DAF chamber,massive of microbubbles attach to the flocs, and bring them floating to the top.The floating solids are harvested by DAF’s top skimmer. After the separation process, clean effluent will be collected and discharged.
The generation of micro bubbles is through the air saturation vessel and air diffuser plates.A portion of the DAF effluent is recycled to the air saturation vessel to mix with air by venturi jet under high pressure,and form air dissovled water(white water) .When the air dissoveld water flow to the air diffuser plates, the sharp reduction of pressure will make the microbubbles release from the air dissolved water,and form massive microbbubles.

JORSUN’s SDAF is the perfect combination of sedimentation and DAF to achieve high efficient and solid-liquid sedimentation. It has inclined plates installed inside the tank.

JORSUN Dissolved Air Flotation Plants are successfully operated for a wide variety of industrial and municipal applications, such as:
B- Beverage; Biological effluent;
D- Dairy (milk,ice cream,yogurt etc);
E- Electrinic;
F- Farm; Food(noodle,cookie,bread ,starch,sauce,flavours and fragrances etc);
L- Leachate
M- Meat processing(chicken,beef etc) ; Mine; Municiple;
O- Oil refinery;
P- Package (fruit,shrimp,food etc); Painting; Paper; Pharmacy;
R- River; Rubber glove;
S- Semiconductor; Slaughter; Steel;
T- Textile and dyeing;
