Whether it's wastewater treatment that combines biological treatment
with membrane filtering (MBR), or pure water treatment for drinking water,
Sumitomo’s membrane treatment experts can propose high-performance systems
that maximize the functions of the POREFLON membrane for water and wastewater treatment.
Sumitomo provide world-class membrane treatment facilities at reasonable prices, with complete service programs.
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.
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.
This video gives a basic introduction to the POREFLON Membrane Processing System, including the benefits of the system, various test results and the installation track record.
