The dissolved gas system technology is widely used in water supply and drainage and wastewater treatment in recent years, and can effectively take out the frivolous flocs which are difficult to precipitate in the wastewater.

Characteristics of dissolved gas system

1. Large processing capacity, high efficiency and small land occupation.

2. The process and equipment are simple in structure, easy to use and maintain.

3, can eliminate sludge expansion.

4. Aeration in the air during air flotation has obvious effects on removing the surfactant and odor in the water. At the same time, the aeration increases the dissolved oxygen in the water, which provides favorable conditions for subsequent treatment.

5. For low temperature, low turbidity and water sources with many algae, the best effect can be obtained by air flotation.

In the dissolved gas system, the sewage after the dosing reaction is effectively entered into the air-floating mixing zone, and is directly mixed with the dissolved dissolved water after use, so that the floc adheres to the fine bubbles and then enters the air-floating zone. . The floc floats on the surface of the water under the action of air buoyancy to form scum, and the lower layer of clean water flows to the clear water pool through the sump, and a part of the reflux is used for dissolved gas, and the remaining clean water flows out through the overflow port. After the scum on the surface of the air floating pool accumulates to a certain thickness, it is scraped into the air flotation sludge tank by a scraper and discharged.

The dissolved gas system is a sewer that needs to be cleaned during operation. It can be used to dig open channels, or it can be directly connected to the regulating tank by pipes to flush out the water in the air floating pool. The connection pipe between the sewage inlet and the reaction tank should be as short as possible to prevent the floc from being damaged in the pipeline.www.khnwatertreatment.com
