QDAF Aerator is the main component of QDAF series Cavitation Air Flotation Machine(CAF) machine. It uses the high speed rotation of motor to drive the impeller to rotate at high speed. When the aeration impeller rotates at high speed under water and stirs the water flow, it generates negative pressure and inhales air through the air suction hole. After the impeller at high speed in the water will bring into the air at the bottom of the pool body cutting micro air bubble formation, the coagulant and flocculant, under the joint action of suspension physical flocculation and chemical flocculation, forming a large suspension floccules, under the effect of bubble group of ascending "floccules" floating on the liquid surface scum formation, utilization of slag scraper separation from water.
QDAF series Cavitation Air Flotation Machine(CAF) machine is a new type of solid-liquid separation equipment specially designed for removing grease, colloidal substances and solid suspended solids from industrial and municipal sewage. For different wastewater, by adding appropriate flocculant and coagulant aid, COD and BOD can be removed more than 30% to 80% in this pretreatment stage (the use of agents and removal efficiency need to be determined by experiments). The removal rate of oil and suspended matter is more than 80%-95%. Adding decolorizing agent and dephosphorizing agent can effectively remove chroma and phosphate ion.
Noted: By adding appropriate chemical agents, the removal rates of suspended particulate matter (SS) and Oil can reach above 90%.
Application

Working Process
Features
1. Large amount of water treated by monomer and fast microbubble generation.
2. Simple installation, low noise, simple maintenance and operation.
3. Single or multiple parallel machines can be selected according to the actual amount of water treated.
4. Negative pressure suction, no air compressor and gas tank, low power consumption.
5. Adopting no mechanical seal structure solves the problem of bearing water damage caused by scale damage of mechanical seal due to high hardness of sewage.
