Audited Supplier HFGQF efficient shallow air flotation
Purpose
In outdoor practice, air flotation is one of the effective methods for purifying oily wastewater, suspended solids, algae, etc. with a specific gravity close to water.
Widely used in drainage engineering. Firstly, it is used for algae removal and oil reduction in waterworks that use lakes as water sources; Secondly, it is used in industrial wastewater treatment engineering, such as petrochemical, textile, printing and dyeing, application, tanning, food industry, and other fields; Thirdly, it is used for the recovery of useful substances in wastewater, such as papermaking and pulp water.

Characteristics
The effective water depth is relatively shallow, ranging from 750 to 950mm.
The hydraulic retention time in the pool is short (5-10 minutes).
1, High purification capacity, i.e. high surface load.
2, Small footprint, light unit load, all prefabricated components assembled without the need for an operating room, equipment can be installed overhead or assembled in multiple layers.
3, Low installation and maintenance costs, easy to clean.
High purification level, with a removal rate of over 90% for suspended solids such as algae, and a sludge concentration of 35% after concentration.
The device adopts a GFA type gas dissolution system, which has a clever structure and a gas dissolution efficiency of over 90%. It has multiple technologies and possesses super strong anti clogging ability that other gas dissolution devices do not have.
Construction and working process
Air flotation separation technology refers to the process of allowing air and water to dissolve into water to a greater extent under a certain working pressure, striving to be in a saturated state, and then releasing the pressure dissolved gas and water through reduced pressure, generating a large amount of micro
Fine bubbles come into full contact with the suspended flocs in water, causing them to adhere to the micro bubbles and float to the water surface together with the bubbles, forming scum and scraping off the scum, thus purifying the water quality. The GQF high-efficiency shallow air flotation device developed by Gongyuan Company is an advanced rapid air flotation system. It successfully applies the "shallow theory" and "zero velocity principle" on the basis of traditional air flotation theory, and through precision
Heart design, integrating flocculation, air flotation, skimming, and mud scraping, is an efficient equipment for water quality purification and treatment. "
The GQF type high-efficiency shallow air flotation device addresses the shortcomings of traditional air flotation tanks by designing its raw water inlet and purified water outlet as mobile devices to shorten the time for bubbles to float in the raw water. This means that while the raw water flows towards the air flotation tank, the water distribution pipe in the tank moves in the opposite direction of the raw water outflow, so that the raw water entering the tank is basically in a relatively static state. In this way, the bubbles in the water float towards the water surface along the vertical direction, and the floating speed is increased The floating speed of solids in the near raw water is 4~250px/min, so the suspended solids in the raw water can quickly float to the surface, while the purified water under the scum remains in place. When the purified water collection pipe is moved here, the purified water can be discharged outside the pool. In order to ensure synchronous movement of the inlet and outlet ports, the machine is designed as a circular shape, with the inlet and outlet pipes placed on a rotating frame to rotate around the viewing center. This moving water distribution method produces a "zero speed". The suspended solids in the raw water float quickly from the water to the surface, and the raw water can meet the purification requirements in three minutes.
The overall shape of the equipment is cylindrical, with a compact structure and a shallow pool. It includes components such as the pool body, spiral water distribution mechanism, dissolved gas release mechanism, rotating frame, water collection mechanism, skimming mechanism, dissolved gas system, return water pipeline, and electrical control cabinet. The water inlet, outlet, and sludge discharge ports are all located in the rotating area of the equipment. The water distribution mechanism, water collection mechanism, and dissolved air release mechanism are tightly connected to the frame and rotate around the center of the tank. This device provides a complete set of equipment assemblies and control systems, which are combined with centralized and decentralized control to achieve better operation of the equipment.
