The Hangzhou Nbond Nonwovens Co., Ltd project uses high-efficiency dissolved air flotation produced by our company for pretreatment to reduce the content of organic matter and suspended matter in the landfill leachate. After air flotation pretreatment, the suspended matter concentration removal rate reaches over 90%. The grease removal rate reaches over 95%, significantly reducing the burden of subsequent biochemical treatment.

This case study introduces how Environmental Protection Technology City Industrial Wastewater Treatment Plant Project uses our factory's high-efficiency dissolved air flotation to treat oily wastewater, such as machining and cutting fluids. After treatment, the effluent quality was significantly improved, the effluent indexes of animal and vegetable oils and petroleum reached about 1 mg/L, and the total phosphorus removal rate was over 98%.

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.

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.

This case study highlights the use of our high-efficiency dissolved air flotation at a paper mill in the Philippines for pre-treating papermaking wastewater. This treatment ensures that the wastewater meets the water quality requirements for secondary and tertiary treatment.

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
