Brackish Reverse Osmosis 500,000 GPD - Pakistan

Product Description

Brackish water reverse osmosis would work to purify water that comes from a well, lake, or river. Brackish water is typically a combination of pure water and seawater leaving in at a medium level of salinity. A medium level of salinity however, is not acceptable for consumption. The process in which the water goes through in order to be pure is referred to as reverse osmosis. Reverse osmosis provides those who do not have consumable water with the opportunity to purify a necessity for livelihood. Totally dissolved solids (TDS) and total suspended solids (TSS) are lowered due to reverse osmosis which reflect in how many parts per million (ppm) are in your drinking water. The normal ppm for consumable water would be around 500-600, however, the majority of places around the world well exceed that with thousands of ppms making it difficult to survive. Reverse osmosis offers those who need it, pure water.

In early 2005, Pure Aqua was approached by a client in Pakistan that needs a good quality water for a food and beverage industry. The well water has a high salinity level which is not acceptable to the food and beverage standards; the water had a high content of biological contamination.



Pure Aqua requested a detailed water analysis to narrow down the problem and find a permanent solution. Pure Aqua engineered and manufactured 500,000 GPD brackish industrial water reverse osmosis system complete with advanced PLC control panel and touch screen. The system included the following components:

  • Feed and backwash pumps, high quality materials
  • Pre-chlorination dosing system to oxidize heavy metals and reduce the organic matter
  • Dechlorination dosing system to get rid of the extra chlorine
  • Automatic multi media filters to reduce the suspended solids, turbidity and oxidized heavy metals
  • Industrial reverse osmosis system to reduce the total dissolved solids and any dissolved matters
  • Post chlorination dosing system to have a buffer chlorine for any upcoming bacteria or viruses
  • Cleaning system, to clean the TFC membranes periodically



  • We have drinking water which is available
  • We help in the conservation of habitats
  • We have water for the agricultural sector
  • Helps preserve current freshwater supplies
  • Positive environmental effects
  • Proven and effective methods
