Best Practices for Dealing with Swarf Slurry in Glass Fabrication

Swarf slurry, the semi-liquid mixture left behind after the glass fabrication process, presents challenges for shops. It can’t simply be dumped due to strict EPA regulations, nor can it be reused until it’s been properly treated.

After many years of solid-liquid separation experience across multiple industries, including glass fabrication, M.W. Watermark™ has developed a system for dealing with glass wastewater that benefits shops in more ways than one.

Challenges with Swarf Slurry

There are several individual processes involved in glass fabrication that generate wastewater. These often include:

  • CNC Work Centers
  • Waterjets
  • Edgers / Grinders
  • Beveling and Mitering
  • Drilling, Sanding and Milling

This wastewater is made up of water and fine suspended particles. The good news is that the water can be reintroduced back into the fabrication system. However, it must first undergo a filtration process to separate the water from the solids.

This is because these contaminants can actually wreak havoc on the shop’s equipment, causing damage and clogged pipes. As a result, shops may be faced with significant repairs and downtime. So, the question remains of how to best filter and treat the slurry.

Glass Wastewater Solutions

M.W. Watermark has developed a glass wastewater treatment recycling system to deal with the swarf slurry. Here’s a breakdown of how it works.

  1. Wastewater is pumped from sumps to a swarf slurry holding tank.
  2. Slurry pump moves it from the tank to a filter press.
  3. Filter press filters the water, leaving behind a filter cake.
  4. Clean water moves to a filtered water tank.
  5. Clean water is pumped back into the glass fabrication system for use in grinding, beveling, mitering, drilling, sanding and milling.

Recycling the slurry is ideal because it helps cut costs on water and sewer bills and offers a more convenient solution for glass fabrication shops. Plus, it helps conserve the earth’s water supply in compliance with government regulations.
