Supply efficient dissolved Portable air/gas-liquid mixture pump air flotation/coagulation air flotation equipment


Principle of high-efficiency dissolved air flotation

The high-efficiency dissolved air flotation device is a new type of integrated solid-liquid separation unit that ideally combines conventional dissolved air flotation and inclined lamellar shallow precipitation technologies, which is able to remove flocs and oil drops with lower specific gravity than that of water by shallow dissolved air flotation and then remove suspended particles with higher specific gravity than that of water by inclined lamellar shallow precipitation, thus applicable to sewage water of complicated quality situation with high content of suspended solids.

During sewage treatment with high-density inclined lamellar type dissolved air flotation unit, sewage firstly enters a tubular reactor mounted with a chemical dosing device, where chemicals and sewage are fully mixed and reacted to form large flocs; then, sewage is piped into the shallow dissolved air flotation reaction area at the top of equipment, when part of flocs will absorb microbubbles released by the bubble releaser; as a result, the flocs, with decreased specific gravity lower than that of water, will float upward to the liquid surface under the buoyancy action and finally be scraped by the sludge scraper into the sludge tank; the other part of flocs with higher specific gravity will precipitate downward to the inclined lamellar precipitation reaction area, and finally precipitate onto the inclined lamella and gather in the conical hopper for concentration, while the clean water treated by air flotation and precipitation will flow along the diversion layer into the pure water area and meet the requirements for effluent.

This device is especially applicable to treatment of oily wastewater, tannery wastewater and other sewage with complicated content of suspended solids.

High-density inclined lamellar type dissolved air flotation unit


1. Uses

In the process of water supply and drainage treatment, the separation technology of solid and liquid as well as equipment is one of the key projects. Air flotation is one of the most effective methods for the removal of the fine particles suspended which are close to the water in the proportion.   


2. The representation method of model number


3. Features

1. Small land occupation, little power consumption, easy to operate and simple to manage;

2. High dissolved air efficiency, stable treatment effect, and the integration of control of machine, electricity and instrument;


4. Structure and work process

The WF type combination air flotation device is made up of air flotation tank body, dissolved air system, dissolved air return line, dissolved air water release device, foam scraping device (including combined type, driving type and chain plate type used respectively according to the needs of users) and electric control cabinet and other components.

The major role of air flotation (can reduce COD, BOD and chroma and so on at the same time) is the separation of solid and liquid. Add the flocculant PAC or PAM in raw water, and raw water enters the contact zone of the combination air flotation after the effective flocculation reaction (time, dose and flocculation effect must be experimentally determined). In the contact zone, the micro bubbles of dissolved air water and the floc in raw water mutually bond and enter together into the separation zone, under the action of the buoyancy of the bubbles, the flocs and bubbles rise together to the liquid level, forming scum. Scum is scraped by scraping foam device to the sludge zone. The fresh water in lower layer flows automatically through the collector pipe to clear water pool. Part of fresh water flows back which is used for dissolved air system, and the other part is discharged.

Through the jet flow inhale device, under certain work pressure, return water makes air dissolved into the water to the maximum extent, becoming the dissolved air water, and in air flotation contact zone, through the rapid decompression release of the release device, the dissolved air water forms micro bubbles with the diameter of 30um-50um. The micro bubbles can adhere to each other with the flocs in raw water.

Outline drawing is shown in Figure 1 and Figure 2, the technical parameters are shown in Table 1, and the overall dimensions are shown in Table 2.
