These are ideal for treating underground water with a high mineral concentration that necessitates a more rigorous method of mineral removal. They are able to remove minerals from water at up to 96% reduction levels using membrane technology while retaining vital minerals that are healthy for consumption. Reverse osmosis is one of the most popular treatment methods they employ.
Operation:
STEP 1: Pump water through a filter made of sand media to remove any suspended particles that could clog the RO membranes. STEP 2: To prevent scaling of the RO membranes, an anti-scalant must be added to the water. GE Hypersperse MSI 310 antiscalant will be continually supplied to the pipeline before to the RO process takes place. STEP 3: To retain the natural taste and stability of the water, a chemical dosing pump with a chemical tank will be used to modify the PH. STEP 4: The “pre-treated” water will then be sent through a reverse osmosis unit, which will lower the TDS and condition the water. This water can subsequently be stored in a clean water tank (as determined by the client).
STEP 5: Before bottling, the water will be pumped through a cartridge filter and UV for sterilization, or chlorination if the water is provided directly to points of consumption.
The RO system produces purified water (permeate) from feed water by rejecting all organic and inorganic ingredients via a semi-permeable membrane system. The RO system divides the incoming feed stream into two effluent streams:
I. Because the permeate (treated water) flows through reverse osmosis membranes, it contains significantly fewer dissolved mineral salts and organics for use (usually 96% rejection ratio). The designed recovery of the RO machine is 50-75%.
II. The concentrate (reject water) is the stream that slowly passes past the membrane surface, retaining the contaminants separated from the permeate stream. A particular minimum flow of ‘concentration’ is required to prevent the RO membranes from ‘fouling’ due to the removed mineral salts and organic components.
