Water Challenges:The characteristics of chemicals throughout groundwater is determined by the gases and minerals reacting with the water in its generally slow passage through the Earth’s crust. Extensive variations in groundwater quality are brought by many variables in various water sources. Dissolved minerals such as silica and sulphate produce corrosiveness among water which leads to the deterioration of water treatment equipment, steam boilers, water pipes, etc. Measures to avoid this from occurring involves utilizing active agents that work to minimize these unwanted effects and maintaining pH stability in treated water. If properly treated, the feed water will reach a balance where the additional of more dissolved substances will no longer occur.



Applied Solution: Pure Aqua manufactures reverse osmosis systems to reduce the dissolved solids that lead to scaling. The right RO system design will utilize a high-quality pressure vessel, filter tanks and high-quality instruments such as conductivity, pH and ORP meters. The system included a twin double pass RO followed by an EDI system. The waste coming from both double pass RO’s is treated by a third RO. The waste water coming from the power plant’s manufacturing process is fed to an ultrafiltration system and recycled back to the RO system. Our reverse osmosis and EDI systems were designed to meet the product water requirement for the power plant.

    Nice clean design and I like how they arranged the racks of vessels and piping. The actual NF system is even better than the 3D drawing that we saw.
