Unique UF membrane from HyfluxShop

Kristal UF membranes, designed and developed by Hyflux, have proven performance in treating industrial and municipal wastewater as well as seawater, even in aggressive environments
One of the key components of Hyflux’s advantage that enables it to be one of the leading water and environmental companies is its proprietary ultrafiltration (UF) membranes – Kristal which is used for pre-treatment before the reverse osmosis (RO) process in membrane-based seawater desalination, drinking water treatment, wastewater reclamation, water recycling, and raw water purification and a wide range of other process applications.
The advantages of using UF membranes for RO pre-treatment instead of ordinary sand filters include:
Lower life-cycle costs
Reliability
Excellent and consistent permeate quality regardless of fluctuations in feed water quality
Smaller footprint.
The main functions of UF membranes that underpin its advantages in RO pre-treatment are described as:
Effectively removes all the suspended solids (TSS) from the RO feed water due to sufficiently small pore size of the membranes
Effectively removes bacteria, silicates, colloids, organics, pathogens and viruses, all of which often cannot be effectively removed by conventional pre-treatment or even with microfiltration
Results in an SDI value of the RO feed water always being less than 3 and turbidity being always less than 1, which is also the standard requirement most reputable RO manufacturers will require for the RO feed
