More than 20 years of collaboration to optimise water consumption and improve water quality, eliminate chemical risks and optimise plant maintenance
International Cookware is an industrial glassworks specialising in the manufacture of borosilicate glass (PYREX) utensils and cookware. It uses water mainly to cool components in contact with the molten glass, as well as compressors, transformers and hydraulic power stations.
Classified as an ICPE, the site is subject to a number of energy constraints, in addition to health and environmental requirements. International Cookware therefore turned to BWT for water treatment and management, with the aim of ensuring a continuous supply of cooling water, while reducing consumption and eliminating chemical risks.
Optimising water consumption and reducing health risks
Cookware International uses an average of 12 m3 per hour of borehole water or municipal water to cool its industrial processes, with water circulation of around 500 m3 per hour. As the site operates 24 hours a day, it is essential for Cookware not only to ensure continuity of water supply, but also to optimise consumption and reduce maintenance operations.
The manufacturer decided to call on BWT to deploy innovative and effective water treatment solutions. These solutions had to meet both the site's specific constraints and regulatory requirements, and the manufacturer's desire to optimise the water cycle and eliminate chemical risks.
Effective permanent treatment solutions
For cooling water, the site has equipped its cooling towers with an ECO-MX disinfectant solution generator to combat the risk of Legionella, without using biocides or dispersants. For process water, Cookware has installed softeners to control water hardness, as well as a big bag brine station to reduce the daily handling of salt.
More recently, the company has introduced automatic supervision and injection of cooling circuit treatments, to guarantee satisfactory chlorine levels in line with expected water quality.

"With BWT, we wanted to equip ourselves with permanent treatment systems to overcome the risk of legionella and prevent clogging of the cooling towers. BWT has been working with us since they were established in 1998. They listen to us, talk to us, support us and, above all, provide answers to concerns that go beyond our core business. The teams come in several times a year to look at ways of maintaining the quality of our water. It's a genuine relationship that has been built up over time”, comments J-C Q., Health and Safety, Environment and Energy Manager at International Cookware.
