Industrial Technology Research Institute



Technology Overview


Taiwan relies on imports for more than 90% of its water treatment membranes. In response of the government’s reclamation policy, the water treatment industry urgently needs to independently develop competitive membrane materials. ITRI’s Nanofiltration technology has the characteristics of low operation pressure, high permeability and anti-fouling ability. Through membrane product development and field system verification, NF membrane material and a module system featuring high efficiency and long-term stability were developed.

Applications & Benefits

Field tests have shown that 100 CMD domestic wastewater can be reclaimed with a recovery rate of 75%. Operating costs can be reduced to less than NT$16/ton, which is more optimal than the reverse osmosis (RO) solution used currently.
