When small inflatable flotation devices segment through sewage pretreatment flotation device, equipped with cavitation will flow into the aerator, then water will be in the process of rising through the pneumatic segment generated aerators microbubbles achieve a sufficient mixing flotation equipment maintenance, this time aerator flotation devices will be those of air through the ventilation duct on the water and then transferred to water down. Flotation equipment construction and installation 1) pump suction and pressure pipe and the pump inlet and outlet to take out the same diameter. In the case of the intake air negative pressure pump flotation equipment manufacturer, suction line can sometimes be considered a small diameter gear. 2) dissolving the water pressure at the outlet of the pump should be installed in a gas-liquid separation tank. Liquid separating the upper portion jars set automatic exhaust valve. Liquid separation tank size can pump outlet aperture size roughly selected. 3) should be located on the solution pump out water valve, pressure regulator door after release of dissolved air flotation device line should be short and straight quality into flotation tank diameter should increase after the adjustment One valve, regulating valve near the flotation tank . 4) was dissolved in flotation pool pump can be perforated pipe discharging line mode, opening up. 5) Suction piping should be installed strainer or Y type filter (60 mesh sieve) and a gas flow meter. Between the gas meter and the suction line valve and check valve settings, to avoid re-adjust every time the inspiratory flow pump, turn off the pump to prevent liquid intrusion into the suction line. Flotation equipment is sold, the new Seoul environmental protection (certified), Tianjin flotation equipment provided by the Environmental Protection Equipment Co., Ltd. Weifang 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.
