70m3 304 stainless steel dissolved air flotation machine industrial sewage suspended solids removal

The air flotation equipment is composed of air flotation tank body, dissolved air system, dissolved water return pipeline, dissolved water release device, slag scraper and electric control system. It is mainly used for solid-liquid separation, and can reduce COD, BOD, chromaticity, etc.

Working principle

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.

Application

1. Algae removal and turbidity reduction of lake water and river water in water supply as tap water and landscape water
2. Domestic sewage pretreatment and sludge thickening
3. Papermaking white water pulp recovery and clean water recycling
4. Chromaticity and impurity removal of printing and dyeing wastewater
5. Removal of various heavy metal ions from electroplating wastewater
6. Separation of refinery wastewater and oil pollution
7. Removal of impurities in tanning wastewater
8. Treatment of industrial wastewater from chemical industry, food, wool spinning, slaughtering, brewing, mineral processing, washing, etc

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, easy operation and simple management.
3.The gas dissolving efficiency is high, and the treatment effect is stable. The gas dissolving pressure and the gas dissolving 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.The releaser 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 spare part can generally be purchased locally or outsourced.
