Project Abstract
The project involves the following:Chlorate decomposition to allow increased recycling of spent brine with the chlorine gas generated being converted to the product Sodium Hypochlorite. The increased recycling rate in the brine will bring about an 80% reduction in chloride emission and bring about a reduction in chlorine emission of 75%.Secondary scrubbing of vent gases from the Hydrochloric Acid manufacturing system will bring about a 70% reduction in Hydrogen Chloride emissions to the atmosphere. The scrubbing medium will be used as feed for Sodium Hypochlorite production thereby closing the system loop and eliminating any discharge to the Effluent Treatment System.The project allows for the following benefits:Environmental Benefits:All processes performed at Micro-Bio are inorganic and the company operates its own on-site Effluent Treatment System involving pH correction and dechlorination. The treated effluent is discharged to the River Blackwater.The following reductions in emission will be achieved:Volume: 20% Reduction in annual discharge volume;Chloride: 80% reduction in annual quantity discharged;TDS: 70% reduction in annual quantity discharged andSulphate: 50% reduction in annual quantity discharged.Emission to atmosphere:Micro-Bio has three licensed emission points. This project involves reductions in two as follows:Chlorine: 75% reduction in annual mass emission andHydrogen Chloride: 70% reduction in annual mass emission.Economic benefits:The economic benefits of the project are marginal. The main benefits are improved environmental performance.
