The flat disc aeration device is a new type of aeration equipment developed in the 1980s. This device produces small bubble diameters, with a smaller gas-liquid interface diameter and a larger gas-liquid interface area, resulting in uniform bubble diffusion and no clogging of holes. It has strong corrosion resistance. It has been tested for oxygenation of clean water and wastewater by the School of Environmental Engineering of Tongji University and the North China Design Institute of Municipal Engineering, China, and has performed well over many years of use by over 50 customers (reduces energy consumption by 40% compared to conventional fixed spiral aeration devices, diffuser aeration devices, and perforated pipe aeration devices, or increases wastewater treatment capacity by 40%). It is particularly suitable for new and expanded urban wastewater treatment plants and the renovation of old aeration ponds, with the option for intermittent operation. Technical Parameters: Aerator Size: 215mm, 260mm, 300mm; Service Area: 0.25 - 0...
