Water Filtration Systems




Every glass grinding application produces particles that enter into the recalculating coolant water loop. When these particles are allowed to circulate through the system, a number of conditions occur that adversely affect production efficiency. Coolant consumption increases. Diamond wheel life and performance decrease. Labor costs increase due to time spent unclogging coolant lines, removing glass swarf from coolant tanks and especially the "dead-time" when productions is stopped while rectifying these conditions. The hidden cost to a typical operation is directly proportional to the number of grinding machines used and can range from thousands of dollars to tens of thousands of dollars per year.

Dealing with glass particulate has made the transition from a necessary nuisance to a viable way to increase shop or plant efficiency.


The Clean 20 is a simple, affordable, effective way to remove glass particulate from process water. It is inexpensive to purchase, install and operate. The Clean 20 is also economical in size allowing it to be used in the smallest of shops or strategically deployed throughout the largest of plants..

Cycle Description

The separation process is quite interesting and is an ingenious concert of gravity and fluid dynamics with a little flocculent to speed things along. Grinding fluid laden with glass particles flows into the unit where a dosing pump precisely meters a very small amount of flocculent into the stream. This mixture of coolant and flocculent are blended by an in-line static mixer. This mixture empties into a secondary chamber for final blending and then to the main chamber in laminar flow. Laminar flow is the movement of water without turbulence. This is critical because any disturbance would impede the efficiency of the settling process. At this point, the suspended particles begin to agglomerate into small “seeds” which gradually grow into a size where they rapidly drop out of suspension into the collection cone. As this settling process continues, the weight of the agglomerated particles and water naturally apply pressure condensing the solids building in the bottom of the collection cone into a progressively denser wet mass. At a preset time, a pneumatic valve empties the solids into a porous collection bag. Subsequent discharges continue to compact the solids and squeeze out the residual water. When the bag is full and completely drained, it is off-loaded for proper disposal.

The CNT16 is a compact, affordable, effective way to remove glass particulate from process water. It is inexpensive to purchase, install and operate. The CNT16 is compact and simple to install allowing it to be used from small shops to multiple units installed throughout larger plants to meet the demand for clean process water. This unit uses centrifugal force to separate glass particulate from the processing water. The glass particulate collects on the wall of the unit’s removable drum and the “cleaned” water recirculates to the equipment. Periodic cleaning is simply stopping the unit and emptying the glass sludge from the drum.

Dealing with glass particulate has made the transition from a necessary nuisance to a viable way to increase shop or plant efficiency.

Chemwest Particle Removal Systems

Chemwest Particle Removal Systems, distributed by SALEM Flat Glass & Mirror, are manufactured in four sizes ranging from 50gpm to 400gpm and are designed to remove glass fines from cutting fluids. Particle removal systems are designed to remove 99.9% of suspended solids from cutting fluid used for cutting and grinding glass panels in the glass fabrication industry. Considered to be a green alternative in the manufacturing process, these particle removal systems automate and recirculate an aqueous coolant.

The system is used for removing particulate and fines associated with the glass cutting and beveling. Fines are removed from the coolant stream by using a coolant and flocculent technology. Swarf is removed from the coolant delivery stream allowing an increased feed rate, improved edge quality, reduced downtime, and an overall lower cost of ownership.


  • Faster cutting speeds
  • Extended diamond tool life
  • Reduced volume of liquid effluent
  • Separation of glass fines from the liquid which can then be treated as solid waste
  • Eliminates the need to run large centrifuge motors 24 hours/day just to keep fluids clean for reduced energy consumption
