What Is Reverse Osmosis?

Reverse osmosis can take you beyond standard softened water, offering more stability, control, and safety. It removes 90 to 95% of microbes, giving you superb levels of purity. Raw ingredients are isolated and your product is kept sterile.

How Reverse Osmosis Works

Reverse osmosis pushes water through a semi-permeable membrane using a high-pressure pump. Salt concentration changes according to the osmotic pressure used, leaving behind desalinated water that lacks minerals and ions. The contaminants are filtered by the membrane, and the reject stream carries contaminants away. The result is known as permeate and has up to 99% fewer dissolved salts.

Cross filtration is used so that contaminant build-up is washed away, leaving the membrane clean.


Reverse osmosis removes bacteria, pyrogens, colloids, and other particles, but it’s not sufficient where complete sterility is needed. The process doesn’t remove sodium ions, calcium, large quantities of CO2, or other chemicals with low molecular weights. It merely softens hard, brackish water needed by the pharmaceutical and supplement industry to maintain quality.

Calculating the Right Performance for Your Needs

Temperature, pressure, and other factors determine a reverse osmosis system’s performance. The RO membrane needs to be managed to keep performance at its peak. Salt rejection rates are a sign of a well-designed system, so they’re an excellent way to monitor the membrane’s performance.

Permeate recovery rates are also indications of a high functioning system. If they rise beyond recommended levels, it means the RO system isn’t removing as many contaminants as it should.

Concentration and Flux

High recovery rates indicate higher salt concentrations, while flux indicates how many gallons of water the system is processing each day.

Reverse osmosis is the perfect way to adapt groundwater for the pharmaceutical and supplement industry. By assuring consistency, it gives you power over your product and keeps your consumers safe.
