Product

HR(High Rejection) Series

It is characterized by its low operating pressure and a high rate of treated water quantity and removal.
The excellent removal performance of TDS, TOC, and SiO2 allows for a wide range of applications in the production of pure water for the purpose of producing ultrapure water used in the electronics and electrical industries.

(Application range: Feed water with a TDS below 10,000ppm)

Applications

General water treatment (Industrial/commercial water, groundwater, wastewater, etc.), High-purity demand industries (electronics/semiconductors), etc.

FR(Fouling Resistant) Series

A fouling-resistant product achieved through special surface treatment, reducing the adsorption of contaminants on the membrane surface and preventing microbial proliferation. It is characterized by its low initial differential pressure, high fouling resistance, and excellent durability resulting in an extended membrane lifespan.

(Application range: Feed water with a TDS below 10,000ppm)

Applications

Public sewage reuse, wastewater reuse, treatment of raw water with high microbial contamination (COD), etc.
