There are two types of inner wall diameter of 62.5mm and 65mm when the hose is aerated .

Performance characteristics and advantages:

1 , the hose wall thickness of only 2mm, the airway is short and straight, the pressure loss is small, the inner and outer tube surface finish, the biofilm is not attached ; circular line of dirt easily accumulate. The hose swells during aeration and is squashed when not aerated. When squashed, the variable orifice is in a closed state, so no matter how long or short the aeration is stopped, it will not be blocked. It can effectively prevent sewage backflow during intermittent operation.

2 , the small-diameter bubble aeration apparatus, a large gas-liquid interface, gas bubbles uniformly dispersed pores less prone to clogging, corrosion-resistance, surprising aerator suitable for urban sewage, large factories, construction, expansion and transformation of the old aeration tank , And the aeration tank can operate intermittently.
