What is the minimum feed water pressure recommended for treating water with 350 TDS?

The minimum feed water pressure recommended for treating water with a Total Dissolved Solids (TDS) level of 350 mg/L typically falls within the range of 35 to 60 PSI for effective reverse osmosis (RO) operations. A pressure near the higher end of this range ensures adequate performance of the membrane and optimal permeate flow while minimizing contaminants.

The selection of 36.5 PSI aligns closely with this pressure requirement, as pressures below this level may lead to inefficient performance, reduced water production, and may not sufficiently overcome the osmotic pressure created by the TDS level. Maintaining proper pressure is crucial for achieving the desired quality of purification and the effectiveness of the system over time.
