Product Description

Efficient shallow air flotation is an excellent sewage treatment technology with reasonable design, convenient operation and economical operation. Efficient shallow air flotation is mainly used for the purification and treatment of industrial wastewater such as papermaking wastewater, chemical industry, printing and dyeing, and food. In order to achieve the ideal use effect, an ultrafilter with a deflector is used for pretreatment to remove the coarse SS impurities in the sewage, reduce the operating load of the air flotation machine, and reduce the amount of flocculant in the subsequent treatment process. changes have a strong ability to adapt.

Efficient shallow air flotation can also separate algae, fine suspended solids and microaggregates in groundwater and water; useful substances in industrial wastewater can be recovered, such as pulp and fillers in papermaking wastewater, instead of secondary sedimentation tanks to separate excess sludge concentrate. It is especially suitable for the separation and recovery of suspended oil and emulsified oil in oily wastewater, and the separation and recovery of ionic substances such as surfactants and metal ions.

Working principle

Efficient shallow air flotation adopts the principle of dissolved air flotation, which is to inject part of the dissolved air water into the water to be treated, and use the tiny bubbles released from the dissolved air to float the suspended solids or oils in the water to the water to be treated. surface, so as to achieve the purpose of solid-liquid separation. The shallow air flotation tank is very shallow, and the general water level is controlled at about 600mm, which greatly shortens the air flotation time and has high air flotation efficiency.

Efficient shallow air flotation makes the water evenly distributed, and the released water rises directly without cross flow, avoiding the effect of cross flow on buoyancy. The continuous operation of the rotary bucket mud collector can remove the suspended matter accumulated on the upper layer in time, with little interference and avoid the re-sinking of the floating matter.

Advantage

Efficient shallow air flotation dissolved air tank has a unique structure, small volume, and good dissolved air effect; the releaser has characteristics, and the release is uniform, which is conducive to improving the air flotation effect; there is a continuously running desilting scraper near the bottom of the tank, which is convenient for timely removal of mud sand to ensure a clean and effective air flotation depth at the bottom of the pool.
