A major chemical plant located in northern Europe manufactures plastics and specialty intermediates which are then sold to a wide variety of industries. As part of its commitment to sustainability, the company drives a continuous focus on the identification of new ways to optimize water usage, minimize wastewater emissions, and to reduce costs across its operations. Nalco was asked to evaluate new opportunities to reduce the water consumption by on-site cooling systems, while safeguarding the operational efficiency of the critical heat exchangers.
Nalco’s 3D TRASAR cooling water management program delivers on-demand control and optimization of cooling water chemistry and microbiology, continuously protecting the system from corrosion, scale formation, and microbial infection.
Along with the cooling technology, a team of highly trained engineers, chemists and industry experts, consistently made recommendations for operational improvements and also took immediate action in response to any alarm conditions
The success of using 3D TRASAR technology allowed management at the plant to recycle the wastewater stream to the cooling system, and replace 65% of the current potable water demand. This has delivered a major reduction in the Total Cost of Operation through better water resource utilization and improved asset reliability.
The implementation of the technology has delivered tangible benefits in terms of system control, water reduction, and integrity of the assets involved, along with reductions in cost, and continued protection of public health. Sustainability performance has been improved through reduced demand for fresh water.
