Abstract:

This article demonstrates a low cost real time monitoring and bacterial contamination detection in drinking water at water treatment plants, water distribution systems and consumer sites using Oxidation Reduction Potential (ORP) measurements. In traditional system measures ORP values manually at source end and report to concern officials at selected locations in irregular intervals. In the proposed system has a low cost 32-bit-microcontroller based ORP sensor module and GSM modem was used to detect the bacterial contamination in real time (online) continuously .The collected information will be verified with pre defined allowable range and updates the water quality information to consumers as well as water board authorities and water companies. A two element/electrode ORP sensor module was used to monitor the Redox potential. A sensor assembly consists of a reference electrode made up of Ag/Agcl and measuring electrode made up of platinum tip for stable and accurate measurements. The experiment results were demonstrated the ORP levels for effective utilisation of water for both drinking and non-drinking purposes.
