Use bridge sand suction machine is mainly used for sand water treatment of urban sewage treatment plant or tap water aeration grit tank, the grit at the bottom of the sand, cinder and other larger particles and sewage mixture to the pool side of the sand discharge tank: according to user requirements, oil skimming, slag skimmering device can be added.

rotary brush aerator is suitable for aeration and pushing of push-flow oxidation ditch, and is the main equipment of oxidation ditch sewage treatment system. It has the characteristics of high power efficiency, large oxygen charge, low noise, stable and reliable operation.

oxidation ditch aerator belongs to the horizontal shaft disc type surface push flow aerator in the mechanical aerator. The aerator is composed of an aeration turntable, a horizontal shaft and its bearings at both ends, a motor and a reducer. Made of lightweight, high-strength, corrosion-resistant FRP die-casting, the overall structure is reasonable, light weight, high strength, the surface of the turntable has trapezoidal bumps, circular pits, so as to increase the amount of air brought into the mixture, enhance the ability to cut bubbles, push the mixture, the installation density of the turntable can be adjusted, easy to adjust the number of turntables installed on the unit according to oxygen demand, each turntable can be independently disassembled and assembled, convenient for maintenance.

1, the gas diffusion rubber plate of the diaphragm microporous aerator is made of high-quality synthetic rubber, the bubble diameter diffused by the rubber diaphragm is small, the gas-liquid interface area is large, therefore, it has a high mass transfer rate and high oxygenation efficiency, so that compared with other current aeration devices, it can greatly save electricity consumption and reduce the operating cost of sewage treatment.
