Product Description
Puri-guard® 600 gpd RO membrane is high efficiency products, especially for Europe and some of special customers use. The 600 gpd RO membrane element is designed for treatment of low-salinity water resources such as tap water, well water and some other suitable water. Working under extra low pressure, and it is applicable to water purifying devices for residence, hospital and lab use.
High flow Membrane 600GPD applications
- Tankless RO systems, direct-supply
- High -flow under0sink systems
- Small commercial steups
pay attention
removes 95-98% +TDS (salts , metals ,etc)
Filtration down to -0.001 micron
Often needs high pressure (booster pump) to reach full output good performance
Pay attention
► Before the membrane (includes 600 gpd RO membrane) leaves from the factory, the Dry membrane element has no preservation solution. The Wet membrane element has 1.0% sodium bisulfite (in Winter, add 10% of propylene glycol antifreeze) as the preservation solution for storage treatment and use vacuum packaging.
► Dry membrane elements should always be maintained wet after Soaking; when wet membrane elements are not used for a long time, preservation solution is needed to soak the elements.
► When the membrane element is used for the first time, it is recommended to flush it first for 15-25 minutes at low pressure (not suitable for soaking or soaking overnight), and then flush it for 60- 90 minutes at high pressure (the water flow should not be less than 50% of the system design water flow).
► The permeate water and concentrated water within the first hour of the initial operation of the membrane element should all be discharged.
► The operating limits and operational guidelines given in this technical information are part of the limitations of the three-year warranty on the membrane element.
► The addition of any chemicals that may affect the membrane element during storage and operation is prohibited.

a. When pH >10, the maximum allowable temperature for continuous operation is 95℉ (35℃).
b. Under certain conditions, the presence of free chlorine and other oxidants will lead to premature failure of membranes. Therefore, it is recommended that the membrane be pretreated to remove residual free chlorine before water comes into contact with membranes.
