Product Description

Shallow air floatation devices are widely used in water supply and drainage treatment projects. First, applying it to the water treatment water source of the waterworks as the water source, the algae reduces the turbidity.

Structural Principles

1. Sewage flows to the sump through the trench to balance the water quality and quantity;

2. The sewage lift pump is then lifted to the shallow air flotation tank;

3. The shallow air flotation enters the nozzle and adds PAC and PAM, which is fully mixed through the mixing pipe at the bottom of the air flotation tank, and then mixed with some positively charged micro-bubbles generated by the dissolved air system, so that the micro-bubbles can be mixed with flocs and waste water. The pollutants are adsorbed and bridged into the air flotation water distribution system;

4. The wastewater enters the air flotation tank through the water distribution system, and the wastewater entering the air flotation tank reaches zero speed in the water distribution area and the air flotation area through the air flotation water distribution system and the stepless speed regulating device;

5. The aggregated flocs and the pollutants adsorbed and bridged by the microbubbles are rapidly separated from solid and liquid under the action of buoyancy and zero velocity;

6. The scum pollutants that are separated and floated in the clear water area of the shallow air flotation tank are taken away by the screw skimmer, and flow to the sludge tank by themselves, and then flow to the scum pool under the action of gravity;

7. The clean water separated in the lower layer flows to the clean water pool through the clean water extraction tank pipe under the rotary bucket;

8. The scum in the scum tank is pumped to the sludge dewatering system, and the filtrate is discharged from the trench to the water leveling tank, and the dry sludge is transported to landfill or comprehensively treated.
