Air flotation can be widely used in water supply and drainage engineering, concrete application is as follows:
1. The feed water of the lake, river water as tap water, landscape water material to remove algae, etc


2. Sewage pretreatment and sludge concentration


3. Industrial water treatment:


Papermaking white pulp recovery and water reuse


Printing and dyeing wastewater chroma and impurity removal


In electroplating wastewater of various heavy metal ions removal


Separation, oil refining wastewater


The tanning waste water to remove impurities


Chemical industry, foodstuff industry, wool spinning, slaughtering, brewing, ore dressing, washing and other industrial wastewater treatment


The main design parameters of air flotation technology including the stay time, flocculation time and surface load rate and reflux ratio, dissolved air pressure, etc.The hydraulic residence time of gas floating pool for 5 ~ 35 min;Surface load rate is 5 ~ 9 m3 / h. (m2).


According to the requirements of treatment effect, can adjust the dissolved air pressure and reflux ratio, and can effectively reduce the operation and maintenance costs.Besides air flotation can solve the problem of precipitation can solve, and due to the short residence time, air float pool construction costs are less than settling basin, but it can get better treatment effect.For the above situation, the processing of air flotation technology is one of the most effective measures, is also one of the key projects of separation technology.
 
A. ZWF type vortex concave type series air flotation machine introduction:
 


ZWF series type vortex concave type flotation machine, is an introduction of the technology advanced sewage treatment equipment, reasonable design, convenient operation, economy running, it is made of micro air bubble aerator, directly to remove suspended solids from the wastewater.Vortex concave aerator will "micro bubbles" without the need to advance in the injected directly into the water soluble gas, and then through the perforated impeller "micro bubbles" uniform distribution in wastewater, so the whole operation process does not happen jam phenomenon, more do not need to be dissolved air pressure, air compressor and the circulating pump, etc.Raw sewage into the dosing first reaction zone, and then into the aeration zone and good contact with micro bubbles, ZWF type vortex concave air floating machine features: the micro air bubble is on the rise in the process of suspended solids float to the surface of slag scraper run along the liquid surface will be suspended to tilt 45 degrees of inclined plate, and then pushes it into the sludge discharge pipe groove, through the sludge discharge pipe groove into the sludge collection area.Sewage purification before emissions will be after a ramp at the bottom of the overflow groove, the overflow tank is used to control water of air flotation machine, ensure the liquid tank into the sludge discharge pipe, open throat flow pipe from the aeration period of stretching across the bottom of the air floatation tank.
