Abstract

The present disclosure relates to method and system for dynamically managing waste water treatment process in a water treatment plant. Operational data related to water treatment process are collected from various data sources and operational parameters are identified at various levels using the operational data. Historical and real-time threshold values of operational parameters are identified based on historic and real-time operational data and real-time operational data respectively. Degrees of significance of operational parameters on the water treatment processes are calculated at each level. Further, plurality of inflection points, indicating optimal range of operational data, are identified based on degrees of significance, historical and real-time thresholds. Finally, water treatment processes are optimized based on inflection points, thereby optimizing power consumption for the water treatment plant. The above method enables large-scale management of the water treatment processes, without actually visiting a water treatment plant, thereby reducing dependency on expertise and skilled resources.
