1、 Product features:
1. Customized products: customized production according to water quality, water quantity, emission requirements, and other requirements;
2. Equipment materials: carbon steel, stainless steel, etc;
3. Equipment Overview: Dissolved air flotation machine is a commonly used water treatment equipment, widely used in fields such as sewage treatment, drinking water purification, industrial wastewater treatment, etc. It utilizes the characteristic of gas solubility in water changing with pressure to dissolve gas in water under pressure, and then releases gas to form tiny bubbles, thereby achieving the purpose of flotation of solid particles;
2、 Technical principle:
1. Function: Mainly used for solid-liquid or liquid-liquid separation (while reducing COD, BOD, chromaticity, etc.).
2. Air flotation process: The wastewater that has undergone a dosing reaction enters the contact zone of the air flotation tank and comes into full contact with the released dissolved water, causing the flocs and microbubbles in the water to adsorb to each other, and then enters the separation zone. The flocs float to the surface of the water under the buoyancy of microbubbles, forming a floating layer. The clear water from the lower layer flows into the clean water tank through the collector and is discharged. After the floating debris on the water surface accumulates to a certain thickness, it is scraped into the floating debris tank by a scraper and discharged. The settled sludge is discharged through the sludge outlet.
3. The generation and release of dissolved air and water: Clear water or air floating water is pressurized by a dissolved air pump and enters a dissolved air tank through a control valve. Under pressurized conditions, air dissolves in the water. When passing through a release device, the dissolved gas rapidly gathers and reduces pressure, releasing a large number of small, uniformly sized, dense, and stable microbubbles.
3、 Application scope:
Dissolved air flotation machines are widely used in water treatment processes in various fields, and have the following application advantages:
1. Sewage treatment: The dissolved air flotation machine can effectively remove organic substances such as suspended solids, suspended oil, and colloids in sewage, improving the treatment effect of water quality.
2. Industrial wastewater treatment: Dissolved air flotation machines can treat various types of industrial wastewater, such as those from industries such as steel, petrochemicals, papermaking, printing and dyeing, and food, effectively removing suspended solids and oils from the wastewater.
3. Water resource reuse: Dissolved air flotation machines can remove useful substances from wastewater, achieve water resource reuse, and reduce dependence on natural water resources.
