Product Description

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.

The RO-200 series can be customized based on individual design to include chemical dosing, cleaning skids, anti-scalant and more. These reverse osmosis machines can accommodate between 600 to 15,000 GPD, with feed water TDS of 1000 ppm to 5000 ppm. These features have the capability of removing hardness, chlorine, odors, color, iron, and sulfur. Economical and efficient, RO-200 commercial reverse osmosis machines acquire the latest in RO technology to remove dissolved salts, particles, organics, minerals, solids and other contaminants from water with a molecular weight greater than 150-250 Dalton.. Pure Aqua uses the most reputable membrane manufacturers such as Dow Filmtec and Hydranautics (USA made)
