Water treatment for glass washing machines

A large international flat glass manufacturer has installed an all-in-one, fully automated plug-and-play water treatment unit for different rinsing zones. The customer has 14 of these units operating at various locations. With years of experience in water treatment for the glass industry, EUROWATER has designed a comprehensive standard solution consisting of:

  • Demineralized rinse water: The water is first pre-treated in an ion exchange softening unit and then demineralized using reverse osmosis, a chemical-free technology. The demineralization process ensures no spots, dirt or residue, and greatly enhances adhesion of PVB film.
  • Water saving: A properly designed recycling process reduces the demand for fresh water. The rinse water is reused/recirculated through a special dual filter that is a combined gravel and activated carbon filter. The filter removes cutting fluid, leftover residue and particles, including glass chips, interleavants, and other contaminents.
  • Storage tank and booster pump: The make-up water as well as the recycling water is collected in a storage tank. The treated water from the tank is supplied to the rinsing zones by a pump integrated on the skid.
  • Automation: The process is completely automated with sensors and triggers that ensures that everything operates smoothly. The unit has been prepared for integration with other control systems.
