What is Industrial Reverse Osmosis (RO)?

The idea of industrial Reverse Osmosis (RO) is to use high-pressure produced from motorized pumps to push water in the opposing direction of osmotic pressure so that the water source with the higher concentration of contaminants is forced to pass through the semi-permeable membrane instead of the water with lower concentration of salinity, or salt content. This allows reverse osmosis (RO) to be put to use on an industrial scale, and for many applications.

How does Industrial Reverse Osmosis (RO) Work?

Whereas with normal osmosis the osmotic pressure is meant to dilute the salt content by filtering the non-salinated water source into the salinated water source, Reverse Osmosis (RO) uses this same concept to push the higher concentration of water through the semi-permeable membrane—separating about 95 to 99 percent of all total dissolved solids (TDS) from the treated water and lowering the salinity in the process.

The more the water is filtered the higher amounts of pressure are required to continue pushing the feed water forward—the Reverse Osmosis (RO) System has to account for the rise in osmotic pressure throughout the Reverse Osmosis (RO) process since the feed water grows continuously salinated. These Industrial Reverse Osmosis (RO) systems are designed to treat tap, brackish, and sea water to produce clean, potable water for human consumption and for use in many global water treatment applications and industries.

Types of Industrial RO Systems

There are two primary types of Industrial Reverse Osmosis Systems, one that treats brackish water, and one that treats ocean and seawater. Due to how valuable fresh water is as a limited natural resource, there are many global industries that benefit from permeate water produced from these systems. Although these systems can be expensive, it is one of the most cost-effective and energy efficient reverse osmosis ways to treat salinated and brackish water, especially as production costs continue to decrease for both Reverse Osmosis (RO) Units and their membranes.

What is Industrial Reverse Osmosis (RO)?

Industrial Brackish Reverse Osmosis (BWRO) Systems

Brackish water is a briny water source that has lower salinity than ocean water and higher salinity than fresh water sources—this can happen for many different reasons—but most commonly in nature this occurs in estuaries. Many One Stage and Single Pass Reverse Osmosis (RO) Systems create briny reject water as well. Two Stage and Double Pass Reverse Osmosis (RO) Systems can reuse this briny reject water as long as the TDS level is within the range of the membranes. This makes Industrial Brackish Reverse Osmosis (BWRO) Systems ideal for treating water with a medium level of salinity, from tap or other brackish sources.

Industrial Seawater Reverse Osmosis and Desalination (SWRO) Systems

Industrial Seawater Reverse Osmosis (SWRO) Systems are designed to treat large water sources with high levels of salinity, from either the ocean or other sources of water with large amounts of contaminants. Depending on the level of total dissolved solids (TDS), some Reverse Osmosis (RO) Systems can also treat the reject water the Industrial Seawater Reverse Osmosis (SWRO) System produces. This is a more difficult task to achieve for Seawater RO Systems than Brackish RO Systems as reject water from Seawater RO Systems have a much higher level of TDS which can easily be beyond the range of the Reverse Osmosis (RO) Membrane.

Another key feature that differentiates Industrial Seawater Reverse Osmosis (SWRO) Systems from Industrial Brackish Water Reverse Osmosis (BWRO) Systems is that Seawater Reverse Osmosis (RO) Systems require more power to produce higher pressure to overcome the greater osmotic pressure in high-salinity water, which can slightly affect the maintenance cost of these systems.

Energy Efficient Industrial RO Systems

Industrial Reverse Osmosis (RO) Systems with Energy Recovery Devices (ERDs) installed will use less energy as the device is designed to capture and reuse energy from high-pressure motorized pumps. This process can save energy for high-pressure pumps by decreasing the amount of horsepower (HP) required to keep them operating, and the Industrial Reverse Osmosis (RO) System as a whole.

How much does an Industrial Reverse Osmosis (RO) System cost?

Every Pure Aqua, Inc. Industrial Reverse Osmosis (RO) System is considered energy-efficient and uses very little power for its size. Most systems can be automated as well, with minimal human intervention required, which in turn lowers costs once again. All this and more place our best Industrial Reverse Osmosis (RO) Systems at the forefront of any industry requiring clean—and desalinated—water.
