Water Treatment
01
Introduction
This technology treats pollutants, impurities, and salinity in water through membranes with pores of various sizes. This is applied to BWRO, SWRO, pure water production, and wastewater recycling.

Features
  • Satisfaction of the demanding water quality by customers
  • Low CAPEX/OPEX due to high recovery rate and low energy design
  • Minimization of the installation area
  • Easy operation and remote control by the automatic system

≤ 5~15 NTU2) -
Nanofiltration
(NF)		 Smaller than 0.001㎛ Organic matters, Agricultural pesticide, Taste, Smell, Synthetic detergent, Calcium ion, Magnesium ion, Sulfate ion, Nitrate, etc. ≤ 0.1 NTU1) 70%
Under 0.1 NTU2) 1000 ~ 2000ppm
Brackish Water Reverse Osmosis
(BWRO)		 More than 93% as salt removal Metal ion, Chloride ion, etc. ≤ 0.1 NTU1) 80~90%
Under 0.1 NTU2) 2000 ~ 5000ppm
Sea Water Reverse Osmosis
(SWRO)		 More than 99% as salt removal Salinity in seawater ≤ 0.1 NTU1) 95%
≤ 0.1 NTU2) 30000 ~ 35000ppm
