Water treatment is always important, but it becomes particularly important when the treated water is to be utilized for civil needs. Water for civil use is that used for drinking, cooking, in the health field, for washing dishes and clothing. In this case, consequences deriving from the treated water concern human health and welfare, and are therefore of primary importance. The use of adequate treatment and distribution systems produce water of excellent quality which can be safely supplied to the community. Some examples of plants constructed by Mosaico Tecnologie for civil use are: - Water purification plants in general for municipal waterworks; - Distribution plants; - Lifting stations; - Systems for water filtering, iron removing and manganese removing; - Water softening and denitrifying plants; - Reverse osmosis systems; - Bactericidal systems which use ozone, chiome dioxide, chlorine and uitraviolet rays to kill bacteria
