Monitoring system prevents drain on water resources

An automotive glass manufacturing plant in Northern Europe is using Nalco 3D Trasar technology and 360 Monitoring Service to improve sustainability performance, by reducing fresh water demand and eliminating zinc from wastewater. As part of the evaluation, Nalco also carried out a full Mechanical, Operational, Chemical and Sustainability survey (MOCS) of the cooling water system. The Nalco cooling water management system delivered better cooling performance through on-line monitoring and control of key system parameters. This also provided plant management with new automated data management functions not previously available, and released staff time for other duties. With the help of the system, cycles of concentration in the system were increased, reducing annual water demand by more than 10,500m3/year and consequent wastewater emissions by 29%. On-line real-time monitoring of system conditions gave the customer continuous assurance of protection from scale, corrosion, and biofouling.
