ABSTRACT:
A water treatment apparatus includes a mixing tube through which the waste water passes for mixing into the waste water a plurality of chemicals for causing flocculation of contaminants. The mixing tube is connected to a settling chamber for allowing settling of the flocculated contaminants and for supplying clarified water at an outlet of the settling chamber. The mixing tube has a plurality of injection members at spaced positions along the duct, each including a pump and a chemical supply for injecting a selected quantity of a selected chemical into the duct and each including a respective mixing member and drive for mixing the chemical into the water in the duct. An electrical separation section is provided in the system before or after the settling and includes a duct, into which the water is introduced and a plurality of amorphous metal plates across the duct arranged to be charged at low voltage.
