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. In total the customer has 14 all-in-one units operating at different locations.With years of experience in water treatment for the glass industry, EUROWATER have designed a comprehensive standard solution consisting of:

  • Demineralised rinse water: Water is pre-treated in an ion exchange softening unit and then demineralised using chemical-free reverse osmosis. This process ensures no spots, dirt, or residue, greatly enhancing the adhesion of PVB film.
  • Water saving: An efficient recycling process reduces freshwater demand. Rinse water is reused/recirculated through a dual filter combining gravel and activated carbon, removing cutting fluid, residue, and particles like glass chips and contaminants.
  • Storage tank and booster pump: Make-up water and recycled water are collected in a storage tank. The treated water is then pumped to the rinsing zones by an integrated pump.
  • Automation: The process is fully automated with sensors and triggers ensuring smooth operation. The unit is prepared for integration with other control systems.
