Backwashing Filter System 4 of  4

Turbo-Disc Skid Systems
The Automatic Turbo-Disc sets the new standard for side-stream cooling tower water filtration. Available in a single-pod model as well as multiple pod models, the Turbo-Disc uses a fraction of the flush water used by traditional sand filters. The Turbo-Disc is effective in removing particulate (sand, sediment, etc.) as well as light airborne contaminants (cottonwood seed, algae, etc.), both of which are commonly found in cooling tower water.

Backwasing Filter SystemQuality of Disc Filtration:
Although the three-dimensional disc media is the heart of the filter, there are other principles at work. As water enters the filter housing, it passes through the Turbo-Element at the base of the disc cartridge. The Turbo-Element spins the water at a high velocity, causing heavier particles (i.e. sediment) to centrifugally spin outward, away from the disc media.

The dirty water passes through the depth of the discs, from the outside to the inside. The discs contain grooves that run radially across the surface of the discs. These grooves are precisely molded in the surface of the discs, slightly tapered from the outside to the inside. On the opposite side of the disc surface, the grooves are running in the opposite direction, therefore creating a cross-hatching of grooves across the depth of the discs. The combination of the Turbo-Element, the grooves molded in the surface of the discs, and the caking effect achieved by the depth of the media, extremely fine particulate removal is achieved.

The discs have tapered grooves that the water passes through. The discs are stacked tightly onto a cartridge frame. The entire disc cartridge fits inside an injection-molded polyamide housing (pod). Each groove alternates direction, causing a torturous path for the water. As the water passes through the grooves, extremely fine particles are trapped in the media. During backflush, the discs uniformly separate and release the contaminants from the surface of the discs.

Benefits of the Turbo-Disc System:

  • Improves Heat Transfer Resulting in a Reduction in Energy Costs.
  • Cuts Maintenance Costs Dramatically By Decreasing Downtime for Cleaning and Repair
  • Complements Chemical Treatment Program Therefore Reduces the Cost of Water Treatment
  • Increases Lifespan of Downstream Equipment Such As Heat Exchangers, Process Equipment, ETC
