ABSTRACT:
A method of purifying wastewater as a fluent coming either from industrial plants or from municipal sewage runs. The method includes the steps of running the wastewater as a fluent into a headworks where some preliminary treatment takes place. From there the fluent is passed into a primary reservoir. The primary reservoir analyzes the fluent as to certain control parameters such as pH, dissolved oxygen and/or dissolved solids. Thereafter the fluent flows into a primary reactor having a plurality of electrolytic cells therein. While in that reactor the fluent is subjected to electrical contacts which are located at the bottom and the top of the reactor. The effluent from the primary reactor passes through a ratio weir into a secondary receptor. The secondary receptor contains sensors for the measurement of control parameters such as pH, DO (dissolved oxygen TDS (total dissolved solids) and chlorine. Thereafter, the fluent is passed to a filtering device. The overall purification system can be termed an electrolytic chemical system.
