From its initial start-up, the RO machine has been working properly with minimal trouble-shooting. A quality reverse osmosis machine is designed to deliver high quality service by removing massive amounts of salt and other impurities from wells, lakes, rivers, and the ocean through a process called 'reverse osmosis". The process of reverse osmosis deals with the use of a high pressure pump which applies extreme pressure to the high saline concentrated side of a semi-porous membrane, combatting a natural process called "Osmosis". Naturally, osmosis transports salt through a semi-porous membrane from a region with low saline concentration to a region with high saline concentration. Its goal is to gain an equal quantity of saline concentration on both sides of the membrane. With the use of the high pressure pump, reverse osmosis comes in to direct osmosis to the opposite direction. The pump applies high pressure to the highly concentrated saline side of the membrane, pushing salty water and other impurities across the membrane, only allowing water molecules to flow through. Salt and the impurities are rejected and later thrown into the drain on the concentrate side. In the end, we obtain purified water with 99% less dissolved salts on the permeate side of the membrane.


Water Challenges: Brackish water normally contains about Brackish is 1000 to 5000 PPM TDS, with highly brackish water containing between 5000 to 12000 ppm TDS. Highly brackish water requires a greater degree of treatment to completely remove of its higher concentrations of contaminants. This means that larger pumps with greater amounts of pressure within the reverse osmosis system are needed to be applied in order to push the salty water and other pollutants across the membranes. The end result will be purified water with virtually all of its impurities discharged from the concentrated side while the treated water is now able to be used for drinking or in other applications.



Applied Solution: Pure Aqua manufactured and supplied Reverse Osmosis System complete with pre and post treatment to a major company in Tanzania. The system was designed to produce 18,000 GPD.



Low operating cost, compact size, reduced footprint, and high quality production of freshwater.
