Flotation devices and flotation water purification flocculant is the core technology, research new composite poly-silicon aluminum Sulfate Flocculant and of CAF device will solve practical problems, sewage flotation equipment, flotation equipment has a very important practical Significance The paper initially established CAF eddy female flotation equipment design and calculation work and theoretical system. Designed for small CAF flotation device prototype, while using PFASSi flocculant flocculant the four main waste water flotation tests conducted Studies flotation devices using new and efficient dissolved air equipment - micro-bubble generator, instead of the traditional air-entraining device to the gas dissolved in water, sets flotation equipment, flotation equipment and install several chute group within the flotation zone including housing, scraping residue machine, screw feeder out together to form a complete water flotation devices. In theory, the treatment effect of flotation and the residence time is not directly linked, Putian flotation device, but only with the flotation area, and if the flotation will reduce water depth H is the water depth H / 10, then the flotation distance and the residence time will be slimmed down 10 times, which is the famous "shallow pool theory." Assembly of flotation equipment, new environmental Seoul (online consultation), Putian flotation equipment from Weifang new Environmental Protection Equipment Co., Ltd. Seoul. The new Environmental Protection Equipment Co., Ltd. Weifang Seoul (www.wfxiner.com) is an industry leader in Shandong Weifang, sewage treatment equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the new Seoul environmental leadership with the staff warmly welcome all inquiries negotiations, Seoul environmental innovation better future.
