Self-cleaning filter protects water cooling systems

Article-Self-cleaning filter protects water cooling systems

The Turbo-Disc, an automatic, self-cleaning water filtration system, is an alternative to sand and gravel filtration that uses substantially less flush water. It filters unwanted particulate and other contaminants from cooling tower water, chilled water, and process water applications through the use of a disk system.

The system contains a series of filtration pods that the water runs through (molding applications typically use two to four pods), which contain a stack of 1/16-inch disks. Each disk contains grooves that act as a micron gap to catch particulate. Once the onboard controller detects a specified differential pressure across the system (in other words, when it thinks the system is clogged or dirty enough) it sends a signal to each pod, triggering an automatic backwash. The disks are separated from each other and sprayed with filtered water to clean the gaps. The dirty water is then routed out through a valve.

The manufacturer intends to sell the systems individually as well as a complement to its Thompson Strainer (previously covered in June 1996 IMM, p. 172). It is designed for full-flow use or side-stream use. The pictured three-pod system with everything included costs in the range of $8500. A less expensive manual version of the system is also available.
