METHOD AND SYSTEM FOR CONTROL OF AN ADDITION RATE OF A HEXAVALENT CHROMIUM CONTROL CHEMICAL TO WATER |
摘要 |
<p>The invention describes a method and system for controlling the addition rate of a contaminant control chemical to a water or wastewater line. The level of hexavalent chromium as a contaminant in the water or wastewater is measured using a spectro-photometric probe placed in the line. Data representative of the level of measured hexavalent chromium content is read into a computing unit, which determines a required contaminant control chemical addition rate based on said level of hexavalent chromium content. The contaminant control chemical is then added at the required addition rate to reduce the amount of hexavalent chromium to a predetermined level.</p> |
