Flat flow dissolved air flotation machine (square)
Flat flow dissolved air flotation machine (square)
Product details
1、 Purpose:
In recent years, air flotation technology has been widely used in water supply and drainage as well as wastewater treatment. It can effectively remove light flocs that are difficult to precipitate in wastewater.
2、 Characteristics
1. Large processing capacity, high efficiency, and small footprint.
2. The process and equipment structure are simple, easy to use and maintain.
3. Can eliminate sludge swelling.
4. Aeration into the water during air flotation has a significant effect on removing surfactants and odors from the water. At the same time, aeration increases dissolved oxygen in the water, providing favorable conditions for subsequent treatment.
5. For water sources with low temperature, low turbidity, and high algae content, air flotation can achieve better results.

5、 Working principle:
The pollutants in sewage are divided into dissolved organic matter and insoluble substances (i.e. SS). Dissolved organic matter can be converted into non soluble substances under certain conditions. One of the methods of sewage treatment is to add coagulants and flocculants to convert most of the dissolved organic matter into non soluble substances, and then remove all or most of the non soluble substances (i.e. SS) to achieve the purpose of purifying sewage. The main method of removing SS is to use air flotation.
After the chemical addition reaction, the sewage enters the mixing zone of air flotation and comes into contact with the released dissolved air water, causing the flocs to adhere to fine bubbles before entering the air flotation zone. Under the action of buoyancy, flocs float towards the water surface to form floating scum. The clear water in the lower layer flows through the collector to the clear water tank, and a part of it is refluxed for use as dissolved air. The remaining clear water flows out through the overflow port. After the floating slag on the surface of the air flotation tank accumulates to a certain thickness, it is scraped into the sludge tank of the air flotation machine by a scraper and discharged.
