ABSTRACT:
A water purification system has a series of sequential operating stations each adapted to remove successively finer suspended or dissolved matter from contaminated water. The sequential steps employed are a pH neutralization step, a particulate precipitation step, a pre-filtration step, a particulate coagulation step and a final filtration step. The particulate coagulation is achieved by means of a novel apparatus for the generation of an especially activated oxygen combined with electrically charged probes for agglomerating the particulate which is filtered in a subsequent station. The initially contaminated water passes through each step in the process and emerges as clean, reusable, water. By employing the process and the system of the invention, the process water is recycled, rather than wasted.
