Water Softening by Nanofiltration – Case Study
Keywords:Drinking water, hardness, ion exchange, membrane technologies, nanofiltration
In this research the object of the analysis was the improvement of a drinking water treatment plant with groundwater as the drinking water source. Improvements included the removal of magnesium and manganese. Improvements also mean choosing the proper water treatment technology that would meet the standards for drinking water quality. Technologies that are suitable for removal of these ions vary in many aspects, from technological challenges to cost analysis. After thorough analysis, the right choice, in this case, was a two-stage nanofiltration (NF) which has a removal rate of more than 90%. The analysis also included a detailed cost analysis.
