In oily sewage treatment projects, various air flotation processes are used to remove oil. The commonly used processes are pressurized dissolved air flotation, vortex air flotation, induced air flotation, and electrolytic flotation. This article aims to analyze and compare the features of these air flotation processes and discuss their applications and appropriate occasions for oil removal.   Read More>

This case study introduces how Changzhou Dongfeng Agricultural Machinery Group uses our factory's high-efficiency dissolved air flotation to treat oily wastewater, such as machining and cutting fluids. After treatment, the removal rate of oil, grease, suspended solids, etc., in the raw water is over 90%, significantly reducing the back-end processing load.   Read More>

The development of dissolved air flotation has gone through the exploration stage in the 20th century, the technological maturity stage in the 1940s and 1950s, the technology application and promotion period after the 1960s, and the technological innovation and optimization period in the 21st century. The development of dissolved air flotation products has evolved from early diffuse air flotation to electrolytic air flotation to impeller air flotation and high-pressure dissolved air flotation. Looking forward to the future, dissolved air flotation will develop rapidly with the support of artificial intelligence and big data technology.   Read More>

This project is Angel (Yichang) Co., Ltd yeast product wastewater. After flotation treatment, the effluent is added with a phosphorus removal agent, pH adjustment, and PAM. After sufficient mixing, it is precipitated in an inclined plate sedimentation tank to achieve the effect of phosphorus removal.   Read More>
