Cavitation air floatation machine

CAF machine is designed for the removal of industrial and urban sewage grease, gum and suspended solids (SS) and design systems. CAF uses the principle of mechanical aeration and chemical flocculation process of combining different types of sewage water quality, sewage ideal materialized equipment. In light of some contaminants in sewage treatment, water treatment may be recycled or discharge and biological treatment technology, completely standard treatment.
    Run Features: HD-AF CAF is an excellent wastewater treatment technology and equipment innovation, reasonable design, easy to operate, the economy, which directly except suspended solids from the waste water produced by the air flotation. Cavitation aerators will "microbubbles" injected directly into the water without the need to advance the dissolved air, then by aeration impellers "microbubbles" uniformly distributed in the water, so the entire operation will not be jammed, and more You do not need the pressure of dissolved gas, air compressors and circulation pumps and other equipment. First of untreated sewage into the aeration shell gas segment, thoroughly mixed with microbubbles, microbubbles in the process of rising to the surface of the water in the suspended solids, scraper moving along the surface material is about the suspension blown tilt metal board, and then push it into the sludge discharge pipe, there are levels within the sludge discharge pipe auger, and collecting the sludge into the sludge collector. Pusher and scraper is driven by the same motor. Only 0.5 hp power, after wastewater treatment prior to discharge will be through the overflow tank beneath the inclined plate, used to control the water level in the overflow tank flotation tank, make sure the liquid does not flow into the sludge tank discharge piping and open pharynx stream section along the bottom of the pipe from the aeration tank flotation stretch, while generating microbubbles, Cavitation aeration opportunity with a reflux pipe Ikebe stretch, while generating microbubbles, Cavitation aeration opportunity reflux pipe The bottom forming a negative pressure zone, the negative pressure causes water to the reflux from the bottom of the pond aeration zone, and then return to the flotation section. This process ensures that in the case of inflow of cases, air is still ongoing.
    How it works: small inflatable section through the inflow of pretreated wastewater containing cavitation aerator, microbubbles mixed sewage in the process of rising through the inflatable section and aerator produced aerators will air on the water Transfer to the underwater pipeline through ventilation. Aerator works is the use of air transport at the bottom of the tube of high-speed rotating impeller bulk gas in water to form a vacuum region, the air on the input surface water by aerators, fill the vacuum, the micro-bubbles and consequent rise spiral to the surface, oxygen in the air also will be dissolved in water. Because the density of the liquid between the gas-water mixture and imbalance, resulting in a vertical upward buoyancy, the SS brought to the surface. Float process, the micro-bubbles will be attached to the SS, SS reach the surface after they rely on the support and maintenance of these bubbles in the water. Floating on the water's SS intermittently by a chain scraper to remove. Scraper along the entire surface movement, and SS from the inlet end floatation tank onto the sludge discharge outlet end of the pipe. Sludge discharge pipe in a horizontal auger, the collected sludge into the mud pool. Sewage flowing into the overflow tank and then purified gravity to biological treatment section. Open return line segment extending from the aeration tank along the bottom of the flotation. While generating microbubbles, Cavitation aeration opportunity with a reflux pipe bottom to form a negative pressure zone, the negative pressure causes water from the bottom back to the aeration zone, and then returned to the flotation section. This process ensures the absence of sewage reflux and water flotation section of about 40% can still work.

System advantages:
1. saving investment
CAF machine no pressure vessels, air compressor, circulation pumps and other equipment, and therefore less investment in equipment.
Small equipment footprint, reduce construction investment. Q = 200m3 / h of CAF (CAF) equipment covers only 36.15m2.
2. Low operating costs
CAF machine because there is no pressure vessels, air compressor, circulation pumps and other equipment, which saves power consumption. Q = 200m3 / h of CAF (CAF) system energy consumption is only 5.435KW, and dissolved air flotation (DAF) systems consumption by up to 65KW.
CAF (CAF) system is very easy to operate, no complicated equipment, so manual operation and minimal maintenance work, reducing labor costs and maintenance costs.
3. significant treatment effect
Oil, suspended solids (SS) removal of more than 80%.
BOD and COD removal efficiency of up to 60%. The dissolved air flotation (DAF) systems for BOD and COD removal rate can reach about 35%.
It can promote the oxidation of sulphides to reduce the sulfur content of the sewage.
4. Simple
The system is easy to operate, no complicated equipment; the entire system consists of only two mechanical parts, unlike the dissolved air flotation (DAF) system includes a pressure vessel, air compressor, circulation pump and many other necessary equipment.
