High Efficiency of
Oxygen Transfer From Air to Sewage - When air flows through
Fine Bubble Diffuser, the air can be divided into very large number of fine bubbles
ascending slowly in sewage. Because of a large number of fine bubbles in optimum
size can stay in sewage for much longer time than air without flowing through
the diffuser. Meanwhile, fine bubbles can have very large gas-liquid contract
surface with sewage. Hence, highly efficiency of the oxygen transfer from air
to sewage can be obtained by using Fine Bubble Diffuser.
Lower
Energy Consumption - To reach certain dissolved oxygen content
in sewage, the higher the oxygen transfer efficiency from air to sewage, the shorter
the required operation time of the air blower. Therefore, the cost of the sewage
treatment can be cut down due to the reduction of the energy consumption of the
blower.
Clogging Prevention by Minimizing Liquid Backflow
- EPDM membrane of Fine Bubble Diffuser is with I shaped pores
design. When no air pressure is applied, the pores of the membrane close firmly
to prevent liquid backflow. Reliably intermittent aeration then avoid pore clogging
of the membrane.
The center of Fine Bubble Diffuser membrane is with
three-O-rings design. When air flow shut off, the smallest one of three O-rings
will fit tightly into the intake opening of the support disc of the diffuser due
to water pressure. At same time, the other two O-rings will attach tightly on
the surface of the support disc. The blockage of the opening can stop liquid backflow
into the air pipe system, then prevent the pore clogging go the membrane. Application
