Summary of Field Trials for Bio Organic Catalyst

1. Bio-Organic Catalyst

Technology Description
Bio-Organic Catalyst [BOC] is a concentrated liquid that contains patented amphiphilic molecules or surfactant. The organic catalyst contains no bacteria and is a nontoxic and biodegradable product. The functional mechanism is attributed to the amphiples molecules, these molecules consist of both a hydrophobic and a hydrophilic element. BOC’s patented amphiphilic molecules attach to components such as bacteria, organics, oxygen, foul gases and also bi-products of decaying organic matter including sulfides, amines, mercaptans, skatole, and other contaminants in the aeration basin. Once they attach the components it then self-organizes into a loose aggregate, creating an ideal situation for biological and chemical reaction to rapidly occur. When molecules are physically close together they form a common aggregate; countless such aggregates are formed across the bin thus rapidly enhancing the speed of biological degradation of the organic contaminants and chemical oxidizing the inorganic pollutants. There are three aspects of the mechanisms of action in BOCs that work synergistically together: oxygenation, solubilisation, and catalysis.

2. St. Mary’s Wastewater Treatment Facility
The plant is located on Thomas Street in the Town of St Mary’s. The plant sees a wide flow rate fluctuation as well as significant variability in the organic concentrations in the incoming wastewater. BOCC was dosed in the anoxic tanks. The anoxic tanks also receive activated sludge, secondary digester overflow, internal recirculation from the aeration tanks and other process effluent. The overflow from the anoxic tanks is fed into the aeration tank. The treated effluent from the aeration tanks overflows into the gravity clarifiers and thereon into UV disinfection before it is measured and discharged to the river. The waste sludge is thickened and stabilized using primary and secondary digester. A second dose of BOCC was introduced in the feed to the Anaerobic Digester; the digested (anaerobic) solids are dewatered and thermally treated to meet Bio-solid Class A requirements. The treated bio-solids are stored in concrete tanks and then pumped out in two times per year for land application.
