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.
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.
Sewage treatment is a crucial aspect of environmental protection projects. It requires proper planning and implementation to ensure its effectiveness. To improve the quality of sewage treatment, a treatment mode of pre-treatment, primary, secondary, and tertiary linkage is established based on the current status of sewage pollution. The joint application of various technologies is used to achieve sound sewage treatment effects. As industry technicians, it is essential to grasp the critical points of sewage treatment accurately, operate reasonably, optimize the technology, and improve its feasibility as the industry develops.Wuxi Yosun Environmental Protection Equipment Co.,Ltd
