Abstract
A system and process for removing contaminants from wastewater where the wastewater is treated into a cleaned water that can be reused or discharged into the environment. The wastewater is transported through purification sections, depending on the system including several of the following: pre-treatment via screening and weirs to remove debris and certain heavy solids; a second pretreatment via a sump; strainer; conductivity solution injection system and electrolytic coagulation system; polymer injection system; inline mixers for mixing the polymer in the wastewater stream; retention tubes for providing residence time for the polymer to react in the wastewater stream; a multi-stage separation system comprised of a plurality of water separation compartments for consecutively separating contaminants from the wastewater stream by removing contaminants that float and heavy contaminants that settle to the bottom; and an ozone treatment system. Except for the pretreatment sections, each of the treatment sections are contained within an enclosure cabinet that includes controller and control panels as well and feed containers for the conductivity fluid and polymer.
