-
- Water quality improvement
- Solid waste, E. coli, and other waste are thoroughly eliminated, allowing use as recycled, irrigation, or drinking water.
-
- Quick turnaround and low cost
- New and enhanced treatment capabilities can be added quickly, without large-scale expansion.
-
- Options
- Chemical cleaning units and aeration tanks can be added for custom designs.
-
- Extensive product lineup
- The standard product lineup has units with processing capacity from 50 to 800 m³ per day.
-
- Technical Service
- Our complete service system ensures reliable long-term use.
Flow of POREFLON Membrane Treatment System
We offer a package system that includes membrane modules for fresh water, irrigation water and wastewater treatment; pumps, blowers and other equipment; flow gauges, pressure gauges and other measuring equipment; and control panels to automatically control it all. This system can be connected to an existing water treatment facility to provide new and additional capacity, on short time frames and at low cost without large-scale expansion.

Operating Structure of POREFLON Membrane Treartment System (Membrane Bioreactor)
Membrane Bioreactor (MBR)
This wastewater treatment method combines a biological treatment process using activated sludge and a physical treatment process using membrane filtration. Organic matters in the raw water are decomposed by microorganisms in the activated sludge, and then the activated sludge is separated into waste and permeate using a membrane.
