OMNIPURE™ Series 55 Technology Overview

OMNIPURE Series 55™ System Treatment Process
The processing function of every OMNIPURE Series 55 unit is the same — regardless of size. The automatic three-stage treatment process for generating oxidant on-demand is simple and proven effective. Operation is 24/7, with continuous collection and treatment of the accumulated black and gray water.
The patent-pending OMNIPURE Series 55 systems have received Bureau Veritas certification for IMO Resolution MEPC.159(55).

Stage 1: sewage is macerated while BOD, TOC and fecal coliform are significantly reduced as the wastewater stream flows through the patented electrolytic “book” cell.

Stage 2: is composed of an electrocoagulation (EC) reactor, a gas-liquid separator (Degassing Column), and a solids-liquid separation tank (Settler). The EC reactor electrolytically enhances the sewage stream with iron particles that serve as nucleation sites forming a flocculation with the organic matter that readily drops out of solution. A defoaming agent is injected into the waste stream between the bookcell and the EC reactor to enhance gas-liquid separation of the stream exiting the EC reactor. Gas generated in both the book and electrocoagulation cells is removed in a degassing column mounted on top of the Primary Settler. A proprietary design encourages disengagement of the entrained process gases from the stream which percolates gently into the Settler. An internal standpipe provides significant reaction time for solids to fall to the bottom of the settler. Liquid with minimal solids exits near the top of the Settler tank.

Stage 3: is a second settling (or clarification/concentration) step. The process stream enters Severn Trent De Nora’s unique clarifier tank where velocity is kept at a minimum to further encourage settling of any remaining flocculants to the bottom of the solids Concentrator. This results in a clear effluent from the top of the Concentrator that meets effluent composition requirements for MEPC.159(55). The solids from the Settler and Concentrator can be handled by the operator as a concentrated waste stream or further processed using Severn Trent De Nora’s patent-pending solids handling unit.
