Reverse Osmosis Systems

What Is Reverse Osmosis (RO)?

Reverse osmosis is a hot topic in the water treatment industry. With the lowest energy requirements, some of the highest recovery rates, and one of the best rejection rates on the market, it's no wonder people are interested in learning more about it. What is the definition of reverse osmosis, though? How does it work?

As anyone could guess, it is the process of osmosis backwards. Osmosis is the passage of water through a protein membrane to equalize the concentration of particles dissolved in the water. The protein membrane allows water to pass through, but molecules larger than water (things like minerals, salts, and bacteria) cannot. Water flows back and forth until the concentration is equal on both sides of the membrane, and an equilibrium is formed.

Let's apply this knowledge to water purification. We want to drink water from a lake or stream, but it contains too high concentration of contaminants like salt, minerals, and bacteria, that make it undrinkable. By applying pressure to water as it passes through a membrane, the water can be forced to move away from the membrane rather than attempting to form an equilibrium like normal. This against-flow motion is where the "reverse" in "reverse osmosis" comes from. A pump works well for this process. Water is forced through the membrane, which like a super-fine particle filter, blocks an extreme majority of contaminants from coming through.

Our systems arrive at your facility ready to run with all filters, membranes, pumps, piping, controls and operating manuals.

Seawater Reverse Osmosis Systems SWRO

we offer a full range of systems. Our units are manufactured to eliminate a large amount of salts and other minerals from seawater using RO. Our equipment does the filtration by employing a high-pressure pump to salty water forcing it through semi-porous membranes denying salts and other organics from flowing through.

The membranes are only tasked to remove dissolved solids while dividing the feed water into purified water and rejected concentrated salts. The salts and other organics are thrown into the brine stream then flushed into a drain. At the end we have purified water that has 99% less dissolved salts. These sea water RO systems have the power to purify extremely high TDS water.
