Ultrapure & Industrial Services, LLC. distributes a wide-range of Reverse Osmosis, Nanofiltration and Ultrafiltration Membranes. We carry membranes from CSM, Dow/Filmtec, Toray, Koch, Hydranautics and GE among others. This offering allows us to provide you with the best possible combination of performance and price to meet your needs.

Reverse osmosis membranes can be provided for various environments including brackish, seawater, low pH, low fouling, high temperature, and low energy/flow. We offer fiberglass and stainless pressure vessels in a variety of sizes and types of elements. We also offer end caps, o rings, brine seals, interconnectors, and vitaulic couplers from the following manufacturers. If the manufacturer of your reverse osmosis equipment is not on our list please contact your local Ultrapure representative. Keep in mind that membrane cleaning is always an option to extend membrane life. We provide membrane cleaning services for both 4" and 8" elements. Our state of the art off site cleaning process is designed to restore RO membranes to or near the original manufacturers specification.

Silt Density Index Matters

The SDI or silt density index is a measure for the fouling capacity of water in reverse osmosis systems. The test measure the rate at with a 0.45-micrometre filter is plugged when subjected to a constant water pressure of 206.8 kPa (30psi). 

Did you know that qualitatively, SDI is proportional to particulates and junk going through your membrane elements. A less efficient system costs you money! Save money with ROsave. Patented GE technology on depth filtration media engineered specifically for the highest degree of protection. This product offers low-pressure drop, high particle/dirt capacity which combines to deliver long life and the optimum protection of high performance membrane elements.

Water Temperature

High Temperature (25-30 C)

  • Design For Lower Pressure = Smaller Pump
  • Warm water has lower viscosity

Lower Temperature (<20 C)

  • Design For Higher Pressure
  • Large Pump
  • LE Elements (CW Option)
  • Cold water has higher viscosity

Does your water temperature change +/- 10 C or more?

Adjust pressure to maintain consistent permeate Flow Variable Frequency Drive (VFD).
