Mainly rely on flotation of suspended solids surface hydrophilic and hydrophobic points. Hydrophobic particles are easily attached to the surface of the bubble flotation devices offer, which can be used flotation. Hydrophilic particles with a suitable chemical treatment can be converted after hydrophobicity. Water treatment flotation, coagulant used to make colloidal particles knot become floc, floc flotation device has a network structure, easily trapped bubble flotation equipment suppliers to improve flotation efficiency. Furthermore, if water surfactant (detergent) may be formed of foam, also increased the effect of suspended particles adhered together. Select the new dissolved air flotation device 1) dissolving pump selection generally choose products based on the corresponding model over the amount of water required pump. Dissolved air pump cast iron or stainless steel. Dissolved air pump suction is about 8% to 10% over the flow of water, sewage treatment capacity is generally about three times the amount of water too. 2) dissolved air impeller submersible dive dissolved air impeller can choose products based on their treatment of water and scope. Flotation equipment manufacturers, the new Seoul environmental (certified), 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 implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
