External Pressure
Dead-end Filtration TypePOREFLON™ModuleFeatures[Large volume water treatment]This system is optimal for applications that require large volume treatment withrelatively low turbidity. *General industrial wastewater treatment, water-insoluble
oil-contaminated wastewater, water purification (ground water, surface water, etc.)[Durability]
Poreflon hollow fiber that has a high tensile strength is durable against shaking andflexing allows use for extended periods.
[Compatible with a wide range of wastewater]
Stable treatment capacity is achieved even for wastewater that contains oil andrefractory organicmatter.
[Chemical resistance]
The module can be cleaned with chemicals from pH0 to 14, including high-concentration
alkalis. It has a well flow rate recovery.

*The following conditions are for reference use and may require changes in operational conditions depending on raw water quality.
