Tube membrane fine bubbles is a pipe made of ABS or UPVC, which is used as a distribution pipe. There are ventilation holes on the wall of the pipe. The distribution pipe is surrounded by a diaphragm made of synthetic rubber. The diaphragm is fixed on the pipe by a metal clip. Laser is used to drill uniformly distributed holes on synthetic rubber diaphragm.

During aeration, air enters between the diaphragm and the tube wall through the air vent on the tube wall of the tubular aerator. Under the action of compressed air, the diaphragm bulges slightly, and the hole opens, so as to achieve the purpose of air distribution and diffusion. When the gas supply is stopped and the pressure disappears, the diaphragm itself will automatically close the hole under the action of elasticity. Because of the effect of water pressure, the diaphragm will be pressed on the wall of the pipe.

Therefore, the sewage will not backflow and plug the hole. However, the diameter of the opening of the diaphragm directly affects the utilization of oxygen, so the diameter of the opening should be appropriate. If the diameter of the hole is too large, the utilization rate of oxygen is low, and the diameter of the hole is too small, the utilization rate of oxygen is high, but the resistance increases. Rubber diaphragm should be aged-resistant, high-strength gum, in order to avoid tearing diaphragm, causing damage to the aerator.

When storing tube membrane fine bubbles, in order to prevent the pollution of cold, heat, direct sunlight, dust, mineral oil and hydrocarbons, do not store near the engine, especially near the blower. Packaging materials containing plasticizers shall not be used. Tube aerator has two important parts, which are connecting hose and aeration disk. They also need correct selection and reasonable maintenance.www.khnwatertreatment.com
