Supply Air Floating Machine Advection Air Floating Machine Pig Farm Sewage Treatment Equipment Dissolved Air Floating Machine

The flat flow dissolved air floatation machine is a kind of solid-liquid separation equipment commonly used in the sewage treatment industry, which can effectively remove suspended matter, grease and colloidal substances in sewage, and is the main equipment in the early sewage treatment.

I. structural features: the main body of the equipment is rectangular steel structure.The main components are composed of dissolved air pump, air compressor, dissolved air tank, rectangular box, air floating system, mud scraping system, etc.

1. The dissolved gas tank produces fine bubbles with particle size of 20-40um, and the adhesive flocculation is firm, which can achieve good air flotation effect;

2. Less use of flocculant and lower cost;

3. Operation procedures are easy to master, water quality and quantity are easy to control, and management is simple.

4. Equipped with backwash system, the release device is not easy to be blocked.

Ii. Working principle: the dissolved air tank generates dissolved air water, which is released into the water to be treated by 5 cubic square flat flow air floatation through the decompression device.The air dissolved in the water is released from the water to form tiny bubbles of 20-40um. The micro bubbles are combined with suspended solids in the sewage to make the suspended solids less than water in proportion, and gradually float to the surface to form scum.The water surface is equipped with a scraper system to scrape the scum into the sludge tank.Clear water from the bottom of the overflow trough into the clear pool.

Scope of use:

1. It is used to remove suspended solids, grease and various kinds of glue in sewage, such as: petrochemical, coal, paper making, printing and dyeing, slaughtering, brewing and other industrial enterprises sewage treatment;

2. For recycling useful substances, such as: paper white water in the collection of fine fibers.
