Smart effluent water management system

Challenge Summary

A system to check water quality and prescribe proper chemical dosage to water in water treatment plants in mines, to ensure quality of water to operational and compliance regulations and in turn effectively use water resources and reduce operational costs

Challenge Scenario

The mining industry uses water resources intensively for their extraction process of metals from minerals, treatment of wastewater is a significant step in reducing pollutants and in promoting the quality of the water ecosystem. The nature of the natural settings, influent shock and wastewater treatment technologies contribute to confusion and variability in the treatment system. Such uncertainties contribute to variations in the quality and operational costs of effluent water, as well as the ecological risk of the recipient waters. Improper dosing results in excessive chemical costs and premature wear of the equipment. Missteps in water management not only increase a mine’s power and operational costs, but they can do irreparable harm to a mining company’s reputation. In some situations leading mines to incur regulatory wrath, resulting in closure and disruption to production and the global supply chain. Water management in mining is ensuring that operational and regulatory compliance limits are met in water and wastewater treatment at mining sites. Hence a system which can optimise the chemical dosing of water, ensure water quality is within compliance limits, reduce energy and water usage is required.
