Commercial Reverse Osmosis RO Systems RO-200


One of our most popular models, the RO-200 Series is a compact, energy-efficient Reverse Osmosis System designed ideally for tap or brackish applications. Our smaller systems are capable of reaching incredibly high recovery rates.


Pure Aqua supplies a full line of standard and fully customizable reverse osmosis systems, all of which are engineered using advanced 3D computer modeling and process design software for accurate and customized solutions.


Reverse Osmosis Series Process


Reverse osmosis machines are tasked with purifying water from water sources such as lakes, rivers, well, and even the sea. These machines utilize a high pressure pump that pressurizes brackish or sea 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 thrown into the brine stream then into a drain.


Custom & High Capacity Systems


Our RO-200 series commercial reverse osmosis units are manufactured to meet important matters such as robust construction, user friendly, environmental friendly and long term reliability.



Product Specification

Operation Specifications


  • Max. feed water temperature: 42°C
  • Equipment upgrade for TDS up to 5,000 ppm
  • Hydrogen Sulfide must be removed
  • Max. Silica tolerance: 25 ppm @ 60% recovery
  • Feed water TDS: 0-2,000 ppm
  • Operating pressure: 150 to 250 psi
  • pH tolerance range: 3-11
  • Max. Iron content: 0.05 ppm
  • Feed water pressure: 20 to 80 psi
  • Hardness over 1 GPG requires water softener
  • Turbidity should be removed
  • Operate at higher TDS by lowering recovery


Note: If the feed water TDS exceeds 2,000 ppm, the system model number changes to BW-XXXK-XXXX, and a suffix is added to the end of the model number: “-5” is added if the TDS is 5,000 ppm or less. Example: Required system to produce 9,000 GPD with a feed water TDS of 5,000 ppm, the corresponding model number is: “BW-9.0K-640-5”.
