DAF dissolved air flotation for coal mining wastewater

CAF is an excellent machine sewage treatment technology, reasonable design, easy to operate, the economy, which produces bubbles of air, removal of suspended solids, oils, gels and other impurities from waste water.
CAF machine
Cavitation aerators will "microbubbles" injected directly into the water without the need to advance dissolved gas, gas dispersion impeller and then through the "micro bubble" uniformly distributed in the water, so the entire operation will not be jammed. CAF mainly by the cabinet, aerators, scraping mud system, etc., does not require dissolved air pressure, air compressors and circulation pumps and other equipment.
Run 2
First of untreated sewage into the aeration zone, mixed with the microbubbles, microbubbles in the process of rising to the suspended solids in the water level along the scraper run the suspension was blown inclined metal plate, and then push it into the tank sludge discharge pipe, flows into the sludge collector tank through the sludge discharge pipe, scraper power only 0.5KW. After wastewater treatment prior to discharge will go through the overflow tank beneath the inclined plate, used to control the water level in the overflow tank flotation tank to ensure that the liquid does not flow into the tank sludge discharge pipe, open pharynx flow conduit from the aeration section extending along the bottom of the flotation tank. While generating microbubbles, cavitation aeration opportunity with a reflux pipe forming a bottom zone of negative pressure, which causes negative pressure water reflux from the bottom of the pond to the aeration zone, and then returned to the flotation section. Under this procedure ensures that no flow into the case, air is still ongoing. Handling capacity of the device is 5-500m / hour, treatment costs about 0.3 yuan / ton waste water.
