100m3 carbon steel dissolved vapor flotation machine Manufacturer Domestic sewage treatment equipment

The dissolved vapor air floatation machine is used to discharge air into the sewage to generate tiny bubbles as a carrier, so that pollutants such as emulsified oil and tiny suspended solids in the sewage can attach to the bubbles to form a suspension, and then float out of the water, scrape into the slag tank through the scraper, and discharge through the slag discharge port.

Equipment composition

The dissolved vapor flotation equipment is composed of air flotation tank body, dissolved air system, dissolved air water return pipeline, dissolved air water release device, slag scraper and electric control system.

Working principle

Air floatation is mainly used for solid-liquid separation (at the same time, it can reduce COD, BOD, chroma, etc.). Add coagulant and flocculant to raw water, and after effective flocculation reaction time, the raw water will enter the combined air flotation contact area. In the contact area, the micro bubbles in the dissolved air water and the flocs in the raw water adhere to each other and enter the separation area together. Under the effect of bubble buoyancy, the flocs and bubbles rise to the liquid level together to form scum. The scum is hung to the sludge area by the scum scraper. The clean water in the lower layer flows to the clean water reservoir automatically through the collecting pipe. One part of the clean water returns to the dissolved air system, and the other part is discharged.

Technical advantages

1. The system adopts an integrated combination mode, which effectively reduces the space demand, occupies a small area, consumes low energy, and is convenient for installation and transportation.
2. High degree of automation, convenient operation and simple management.
3. High dissolved air efficiency and stable treatment effect. The dissolved air pressure and dissolved water return ratio can be adjusted as required.
4. According to different water quality and process requirements: single dissolved air device or double dissolved air device can be provided.
5. Release device is adopted to improve the utilization efficiency of dissolved air water and ensure the stability of air flotation equipment.
6. Low noise compressor is used to solve the noise problem that has puzzled people for a long time.
7. The system adopts standardized configuration, and any accessory can generally be purchased locally or outsourced.
