The commercial RO system utilize a high pressure pump that pressurizes brackish or saline water against the surface of a semi-permeable membrane containing small pores. Water molecules are only permitted to flow through the small pores while blocking impurities such as salt, particles, minerals, and other organics from passing through. These small pores have a strong capability of rejecting bacteria and disease-causing pathogens. At the end of this process, clean, purified water emerges on the lower-pressured side while salts, minerals, and other organics are sent into the brine stream then into a drain.

Commercial Brackish Water Reverse Osmosis BWRO Systems RO-300
Pure Aqua supplies a full line of standard and fully customizable brackish reverse osmosis systems, all of which are engineered using advanced 3D computer modeling and process design software fo accurate and customized solutions.
Regardless of the condition of your water supply, brackish type water is more difficult to treat due to the increased probability for changes in salinity over time. This occurrence ultimately affects water prices since energy usage is elevated and the treatment process is burdened as a result of an upward movement of salinity throughout the groundwater.
A significant aspect for the effective running of a brackish reverse osmosis system is the RO feedwater quality, which becomes resolved by the consistency of the water body and the success of the pretreatment process.
Customizable & High Capacity
Pure Aqua engineers have designed a second line of commercial reverse osmosis systems. This line, RO-300 Series, features systems that are able to purify higher capacities of water and are therefore made with higher quality materials. These brackish RO systems ideally treat tap/brackish water for the application of drinking water or other commercial uses that require ultra-purified water.
Compared to the RO-200 Series, RO-300 Series is displayed vertically and made with heavy-duty materials to withstand the higher capacity that it produces. For example, stainless steel piping is used in RO-300 brackish reverse osmosis system. Whereas, the RO-200 uses standard tubing. The high pressure pump is 316L stainless steel. Each pressure vessel has multi membrane, and the vessels are installed horizontally.
Ultra-high-quality water for specific applications and is customizable depending on the application and source of the water. Pure Aqua, Inc. takes pride in their ability to offer the most appropriate solution for any water treatment need.
Brackish Reverse Osmosis Process
Brackish RO systems require pre-treatment of which is always included in the sale unless the water is already being treated. Pre-treatment systems depend on the quality of water that is treated along with the application. Taking those two into account is how our engineers recommend the most appropriate pre/post treatment for the system. Components of pre/post treatment include multimedia and activated carbon filters along with water softeners and UV sterilizers. A chemical dosing system and/or a cleaning skid are also incorporated into the system.
Brackish reverse osmosis systems are equipped to purify water from rivers, lakes, wells, and the sea. With high pressure pumps, water is pressurized to pass through a finely pored semi-permeable membrane and filter the water. Around 99% of contaminants including salts, bacteria, and other particles are removed leaving the water in its most purified form. The system releases the purified (permeate) water from one stream and the reject filled with concentrated contaminants from another. Depending on the application of the water, post-treatment may be applied.
High Capacity of BWRO Systems
The RO-300 series comes with many similar standard features as the RO-200 series. However, the capacity of RO-300 is a main differentiator between the two. RO-300 series is comprised of brackish reverse osmosis systems that can accommodate between 13,000 to 32,000 GPD with feed water TDS of 1000 ppm to 5000 ppm.
Pure Aqua’s RO systems are capable of removing salts as well as other impurities such as bacteria, sugars, proteins, dyes and constituents having a molecular weight greater than 150-250 Dalton. In addition, these RO systems have the ability to remove color, iron, odor, hardness, sulfur, and chlorine while being economical and efficient through the usage of Dow Filmtec, Hydranautics, and Toray membranes (Our systems are made in the USA).

Industrial Reverse Osmosis RO Water Treatment Process
Industrial reverse osmosis plant includes a multimedia prefilter, water softener or antiscalant dosing system, dechlorination dosing system, reverse osmosis unit with semi-permeable membranes, and UV sterilizer or post chlorination as a post treatment. These RO machines apply the technology of reverse osmosis by transporting feed water through a multimedia prefilter to remove particles that are larger than 10-micron. Then the water is injected by an antiscalant chemical to control hardness fouling that may cause damage to the membranes of the RO machine. These pretreatment options have the capability of removing hardness, chlorine, odors, color, iron, and sulfur. The water then continues into the reverse osmosis unit where a high-pressure pump applies extreme pressure to the highly concentrated solution, separating the remaining salts, minerals, and impurities that the pre-filter cannot catch. Fresh, potable water comes out from the low-pressure end of the membrane while salts, minerals, and other impurities are discharged into a drain on the other end. Lastly, the water is passed through a UV sterilizer (or post chlorination) to kill any bacteria and microbes that still exist in the water.

- Containerized Systems
- High Capacity
- Systemic Process
As the feed water enters the system, the first step of the pre-treatment is the pre-chlorination dosing which is injected into the feed stream. This feed stream is headed to a media filter which is the second component of the pre-treatment process to filter out contaminants larger than 10 microns. Next, the water is injected with antiscalant chemicals to reduce hardness of the water and prevent the RO membranes from fouling. The pre-treated water is then pressurized through the RO membranes to produce ultimately purified water and a reject stream of concentrated contaminants. Generally, industrial applications do not require water to be disinfected. However, depending on the application, a disinfection method can be used by means of Post-Chlorination Dosing or a UV Sterilizer.
