2023 Wholesale Popular Epdm Micro Bubble Diffuser For Aquaculture Or Water Treatment Or Fish Tank
Fine bubble Disc diffusers in aeration tanks for STPs
QK Disc diffusers are used in breaking down of contaminant in biological treatment process, by the highly oxygen transfer efficiency, the installation systems can be customized as process requirements, can be supplied disc only, with or without sealing parts, or complete diffuser systems.
EPDM/Silicone Microporous membrane air diffuser disc is used in supplying air for breaking down contaminant in the biological treatment process, by the high oxygen transfer efficiency. It adopts ABS engineering plastics as the main body and is covered with a special rubber EPDM or silicone microporous membrane.
The micro-holes will automatically expand while the air income and close while no air comes, which avoids the blocking of the holes. A non-return design is to prevent the mixture from entering and blocking the pipeline. The incoming air does not need special filtration, intermittent supply of air and does not block the holes and pipes.
