The Reverse Osmosis (RO) membrane is the core component of your water purifier. It is a semi-permeable membrane with microscopic pores of 0.0001 microns, allowing only pure water molecules to pass through while rejecting 90-95% of heavy metals, dissolved salts (TDS), arsenic, lead, fluoride, viruses, and bacteria. Over time, mineral scaling and chemical deposits clog these micro-pores. At Sai Enterprises, we offer professional, genuine RO membrane replacement services across Mumbai, Thane, Navi Mumbai, and Mira Bhayandar.

We use only premium, high-rejection RO membranes (such as Dow Filmtec, Vontron, CSM, Kent, and Aquaguard original membranes) that are durable and suited for high-TDS water. Replacing a clogged membrane restores the water flow rate, lowers the TDS level, and ensures your family drinks safe and sweet water.

Signs Your RO Purifier Needs Membrane Replacement

• High TDS Output — Purified water tastes salty, hard, or chemical-like.
• Extremely Slow Water Flow — The purifier takes hours to fill the storage tank.
• Excessive Reject Water Flow — The purifier wastes water continuously while output is low.
• Purifier Keeps Tripping — The booster pump runs continuously, causing the unit to overheat.
• TDS Level Exceeds Safe Limits — Output TDS rises above 150 PPM (when input is under 1,000 PPM).

Our RO Membrane Replacement Process

Our technician starts by testing the input and output TDS levels. We check the booster pump pressure, as a weak pump (under 60 PSI) cannot push water through a new membrane. Next, we open the membrane housing, remove the old membrane, clean the housing to remove mineral scale, and install the new membrane with food-grade lubricant seals. We flush the new membrane for 10-15 minutes, adjust the TDS controller, and verify the final TDS level is within the healthy range (80-120 PPM). We service Kent, Aquaguard, Pureit, Livpure, Havells, Blue Star, and LG systems. Contact Sai Enterprises today for genuine RO membrane replacement!
