Aesthetic Water Treatment

Water naturally contains a number of minerals including calcium, iron and sulphur. While these minerals are not hazardous to human health, they can alter the hardness, taste, odour and colour of water when present in high quantities. There are a number of treatment options that are available for in-home use that will remove these poor aesthetic water qualities.
