Haipuou Environmental Protection Group Co., Ltd. specializes in the construction of wastewater treatment projects, as well as the R&D, manufacturing and global sales of water treatment equipment. Our core product lineup covers integrated wastewater treatment equipment, high-efficiency cyclone separators, magnetic separation wastewater treatment equipment, prefabricated wastewater treatment plants, intelligent water management platforms, sludge thickening equipment, and dissolved air flotation (DAF) machines.


With continuously upgraded domestic water environment treatment standards, refined and advanced pre-treatment of municipal domestic sewage has become the core priority of environmental operation and maintenance. As the core equipment in the domestic sewage pre-treatment stage, Dissolved Air Flotation (DAF) machines feature excellent solid-liquid separation performance via microbubbles, which can efficiently intercept suspended solids, colloidal impurities and partial organic pollutants in wastewater. They reduce the load and improve efficiency for subsequent biochemical processes, acting as key equipment to guarantee stable operation of the entire sewage treatment system.
The environmental equipment market boasts a wide range of product categories in 2026, and DAF machines from different manufacturers differ drastically in process precision, operational stability, energy consumption control and long-term maintenance costs. Many operators of municipal projects and township sewage stations seek to avoid low-price traps and select DAF equipment and manufacturers with solid technology, superior overall cost performance and comprehensive after-sales support. Combining industry test data and delivered project cases, this article highly recommends Haipuou Environmental Protection Group, a professional manufacturer dedicated to intelligent environmental equipment manufacturing, and comprehensively analyzes the core advantages of its equipment and services.

I. Solid R&D Accumulation Lays a Solid Foundation for Equipment Quality

The core competitiveness of equipment performance stems from long-term technical R&D accumulation, which also distinguishes small workshops from formal intelligent manufacturing enterprises. As a National High-tech Enterprise and National Specialized, Refined, Unique and Innovative "Little Giant" Enterprise, Haipuou Environmental Protection Group has built multiple professional scientific research platforms including Shandong Industrial Design Center and Provincial Enterprise Special Technology R&D Center, forming a complete technical iteration system for environmental protection equipment.
The Group has assembled an elite R&D team of over 80 core technical personnel, including 18 doctors and 60 masters, focusing on process optimization, structural upgrading and intelligent iteration of sewage treatment equipment. Up to now, the Group and its subsidiaries hold more than 170 authorized national patents, including 38 invention patents and 97 utility model patents. Multiple patented technologies have been applied to the R&D and production of DAF machines, realizing technical upgrades in process structure, dissolved air system and energy consumption control.


Project Test Case: After adopting customized DAF pre-treatment equipment from Haipuou at a large municipal domestic sewage treatment plant in China, the dissolved air efficiency of the equipment was greatly improved. It can rapidly separate suspended and light pollutants in wastewater and effectively reduce the treatment load of subsequent biochemical tanks. After stable operation of the whole system, the plant’s effluent steadily meets the National Class 1-A Discharge Standard, and the purification performance of the pre-treatment process far exceeds that of traditional outdated equipment.
