How much pressure is required for this membrane?

The TFC 1812-75 GPD membrane requires 65 psi for optimal performance and durability. It can also withstand pressures of up to 200 psi, but this may impair the membrane’s performance, life span, and structural damage. 

What is type of feed water is recommanded?

Tapwater and underground water perform best with the membrane. Although some of our clients use it for other water sources, keep in mind that the rejection rate may drop to 95 or 96; otherwise, a higher pressure vessel is required (100 psi).

Are you a Manufacturing company and do you customize products?

Since 2008, we have been producing reverse osmosis membranes for home, commercial, and industrial use. With our OWN auto rolling line and OWN RO flat sheet assembling process, we have been able to supply branded and customized reverse osmosis membranes to retailers, distributors (B-2-B) and end users (B-2-C) across the world, as well as providing both ODM & OEM services.

What is the Salt Rejection percent for the TFC 1812-50 ?

The Salt rejection for this membrane is set at 97%. This is the standard rejection rate for an 1812 75-gallons membrane, though the membrane may perform better than indicated.

The 1812 model is the most commonly used membrane in most standard small RO systems or home water purification machines. Capable of producing 75 gallons/283 liters of clean fresh water per day with only 65 psi pressure. Because it is less expensive than other models in the 1812 series, it is ideal for home use, producing enough clean water at a low cost. To achieve the recommended percentage of RO water salts in your water, the membrane removes 97 percent of the salts solids in the water, leaving It with a pleasant taste and a low TDS level. The membrane performs best at 25°C, which is typically the temperature of most feed water.
