Submerge TypePOREFLON™ModuleFeatures[Durability]
Poreflon hollow fiber that has a high tensile strength is durable against shaking
andßlexing allows use for extended periods.
[Chemical resistance]
The module can be cleaned with chemicals from pH0 to 14, including
high-concentration alkalis. It has a well flow rate recovery.
[Easy handling]
The PTFE hollow fibers are treated to be hydrophilic for ease of transport andinstallation while dry.
[Energy saving(Low operational costs)]
Our original "U-shaped structure" employed at the end bottom prevents activatedsludge accumulation and allows efficient air diffusion.
The above features make it compatible with a wide range of wastewater.
Stable treatment capacity is achieved even for wastewater that contains oil.
