Commercial Reverse Osmosis Process:

Skid mounted commercial reverse osmosis purifier are tasked with purifying water from water sources such as lakes, rivers and wells. 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

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.

The process of an industrial BWRO system is the same as all other RO systems, the only difference is the elevated scale of water and equipment used in the system. This RO-500 series includes top-of-the-line high quality equipment from the tanks to the pumps.
 
For reference on the process of reverse osmosis systems, heed the following:

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.

A diagram of RO system process is shown below.

These contaminants range from total dissolved solids (TDS), salt, bacteria, proteins, metals, organic substances, dyes, and constituents that contain a molecular weight higher than 150-250 Daltons.

Pure Aqua’s comprehensive line of conventional and completely customizable brackish reverse osmosis systems are also engineered through cutting-edge 3D computer modeling and process design technology for precise and tailor-made solutions. 

The parts that make-up this large RO system include spiral membrane elements constructed from one or multiple membrane envelopes that are engrossed around a perforated central tube. The permeate flow is sent through layers of membranes into the envelope and makes its way to the central tube where it sits. The membrane layers are displayed in the picture to the right.

While smaller systems are designed for mostly commercial businesses and other lesser-scale applications, our large reverse osmosis system is produced to perfectly handle manufacturing and healthcare facilities of great proportions. Regardless of what type of system that you might require, a large reverse osmosis system is tailor-made to produce you the cleanest water for consumption or other use. 

The Filtration Phases of Large Reverse Osmosis Systems

A large reverse osmosis system generally consist of distinct filtration and carbon consituents. Carbon filters works in conjuction with a large RO system to eradicate chlorine, chloramines, disinfectants, VOCs and pesiticides that enhances the taste and odor from water. Commercial water softeners also help by softening water that prevent membrane fouling. This multi-filtration method ensures an extremely purified solution for the production of highly pure water.

Modern large reverse osmosis system also incorporate pre-filters to eliminate sand, particulate matter, rust, and turbidity that are capable of causing damage to the membanes. It is crucial that you the steps to safeguard your membranes from these potential threats so they can do their work. RO membranes are very efficient in removing a wide range of salt, dissolved solids, lead, heavy metals, organic & inorganic susbstances, microorganisms. These membranes take in water forced throught he system by a high pressure pump that drives water flow into the pores of the semi-permeable membranes.

There is a storage tank and other water purification options that can be used such as uv sterilizers that kill biological organisms, water deionizer systems used as post-filtration to ensure ultra-pure water.

The Benefits of a Large Reverse Osmosis System

  • Enhanced flavor, smell and appearance 
  • Purifying procedure with high quality 
  • Takes out contaminants 
  • Conductivity/total dissolved solids decrease  
  • Brings down hardness in water  
  • Reduced price for high value   
  • Mitigates alkalinity

Other water treatment systems can minimize contamination and may take significant initiative to operate over time. These units also include additional pollution risks can arise if something fails with that specific system. Your water, however, remains fresher spotless through the use of reverse osmosis.

There are various utilizations that a large reverse osmosis system is suitable to handle in both industrial and commercial industries. Although everybody needs their water to be healthy water supply and nice drinking water, companies require clean water to make the most of their business operations. Food suppliers, health facilities, pharmaceutical companies and industrial cooling towers could all benefit from the reliably clean and fresh water provided by the method of reverse osmosis.

Large RO systems are capable of eliminating other impurities not known by many users such as flouride, arsenic, radium, nitrate, sulfate, potassium, and more. Once these substances are taken out by the membranes, they are discharged and flushed away.

Maintenance is made to be simple and extremely cost-effective. Users are only required to clean and change the RO membranes and filters in use on an occasional basis, including sanitizing the system itself. Our RO-600 large RO system provides a user-friendly option to guarantee pristine water purification.
