Dissolved gas flotation system can handle all types of sewage
- Jul 12, 2018 -

The dissolved gas flotation system is mainly used to treat industrial sewage and wastewater, and can also treat urban domestic sewage, which is used to remove BOD, COD, and algae collection. It is a complete set of automation equipment that refines to the surface of the liquid by buoyancy by releasing a large amount of micro-bubbles into the water, causing it to adhere to the suspended solids in the water.


Dissolved gas flotation systems are widely used in industrial wastewater treatment, such as electroplating wastewater, leather wastewater, municipal wastewater, papermaking wastewater, printing and dyeing wastewater, slaughter wastewater, and oily wastewater. Different sewage treatments will be handled in different ways.


For example, electroplating wastewater and heavy metal wastewater can be treated by adsorption colloid flotation method, which can be discharged after treatment; while leather wastewater and urban domestic sewage are treated by dissolved gas flotation system biological method; papermaking wastewater is vortexed by air flotation The removal rate after machine and coagulation sedimentation is 90%~99.5%.


The dissolved gas flotation system treats oily wastewater by a coagulation air flotation process, and the COD removal rate can reach about 90%. The oily wastewater was treated by air floatation. The COD and SS after wastewater treatment were lower than the GJ emission standard.
