What types of air flotation machines are there in general, and what specific equipment are commonly used for sewage treatment in textile mills?

THAF series vortex concave air flotation machine

Product introduction ※

THAF air flotation machine is a patented product of our company, the patent number is 98? 2? 2 1723.4, which is specially used to remove oil, colloid and solid suspended solids from industrial and urban sewage. For different wastewater, the oil removal rate is above 95%, and most of the solid suspended solids are also removed. In addition, by adding appropriate flocculant and mixing agent, COD and BOD can be removed by more than 60% in this pretreatment stage.

Applicable industries: paint, tanning, oil refining, printing and dyeing, chemistry, dairy processing, fiber production, paper making, food, beverage, slaughter, textile, mechanical processing, municipal sewage.

Performance characteristics ※

Strong adaptability: it has strong adaptability to changes in water quantity and quality.

Economical and practical: THAF air flotation system is simple, with few supporting civil works, and it is installed on the ground, underground or high.

Low operating cost: low power required, simple maintenance and manual operation.

High efficiency: THAF air flotation automatically and continuously removes sludge from wastewater. The low water content in sludge reduces the cost of sludge treatment.

Simple operation: THAF air flotation has no complicated mechanical equipment and does not require professional manual participation.

Odor reduction: THAF is an aerobic process, which solves the problem of odor generated by sludge.

Second, THAF aerator.

THAF aerator is a special supporting equipment for THAF series air flotation machines. The working principle of aerator is to use the high-speed rotation of diffuser impeller at the bottom of gas pipeline to form a vacuum zone in water. The air on the liquid surface is pumped into the water by an aerator to fill the gap, and micro bubbles are generated and spiral up to the water surface, and oxygen in the air also enters the water.

Three. THAF air flotation slag scraper

THAF slag scraper is a supporting equipment of air flotation device in sewage treatment, which is suitable for scraping scum produced in flocculation treatment. It applies the principle of chain drive and designs according to the size of the air flotation tank. It can adjust the slag scraping speed according to the water quality of the treated sewage and the added chemicals, and complete the slag scraping task with minimum power consumption. Slag scraping equipment has the characteristics of adapting to local conditions, flexible slag control, stable operation, convenient operation and long service life.

Fourth, QTRF? Series dissolved air flotation machine

QTRF？ Air flotation machine is a new type of air flotation equipment successfully developed by introducing advanced technology and combining with China's national conditions and industry characteristics. It uses partially treated water to inhale and mix air through a microbubble generator to form dissolved air water, which is released under reduced pressure in an air flotation tank. 20-30? μ? m？ Bubble precipitation is formed, which has high surface area and adsorption capacity, and can well remove suspended solids in sewage with different concentrations. ?

※ Performance characteristics:?

1? Pump suction, suction, pressure mixing, high gas-liquid dissolution efficiency, fine bubbles. 20-30? Micron.

2? Air flotation device can replace booster pump, air compressor, large dissolved air tank and release head, which overcomes the problems of unstable operation and large bubble agitation of traditional devices. ?

3? With automatic conditions, low noise and good energy-saving effect, compared with the traditional air flotation equipment of the same model, it saves electricity? 20-30%? . ?

4? Advanced technology, high treatment efficiency, low operating cost and good effluent quality. ?

Scope of application:? ※?

Paper industry, municipal sewage, chemical industry, beverage industry, printing and dyeing industry, oil refining industry, electroplating industry, food industry, textile industry, slaughter industry, leather industry, dairy industry and so on. It involves the application of suspended solids separation, oil-water separation and purification, flocculation separation, activated sludge separation and so on.
