High purity water production has traditionally used a combination of membrane separation and ion exchange processes. EDI is a process which combines semi-impermeable membrane technology with ion-exchange media to provide a high efficiency demineralization process.

Ultra filtration capable to remove colloids, suspended solids, organic matters, viruses and bacteria and reduce silt density index (SDI) from water, wastewater and liquids.
In the context of water purification, ion-exchange is a rapid and reversible process in which impurity ions present in the water are replaced by ions released by an ion-exchange resin.
Reverse osmosis (R/O) is a water treatment process in which water is forced through a semi-permeable membrane that has very small holes or "pores". Clean water passes through and impurities that are too big to pass through the membrane are left behind and flushed away.
Condensate polishing system is placed between condensate pumps and low pressure feed water heaters. H-OH deep mixed beds with high speed are extensively applied in the system. Generally, flow rate of the polisher is 100 meter per hour.
