Abstract

Water demineralisation is a process for the removal of mineral salts present in water, so the water produced has a high purity. Basically the process is like what is done in water softening through ion exchange process. One chemical parameters in water quality requirements is the number of element content of metal like Fe,Ca and Mg in the presence of water commonly called water hardness conducted by ion exchange. Ion exchanger has a limited capacity in ion exchange capability called exchange capacity. Because of this, ion exchangers or resin eventually becomes saturated. Keywords: water demineralization, hardness, ion exchange
