Industrial Water Purification Systems | STiR Industrial Water Filter
the next generation of industrial water filter systems
Filtra-Systems has been providing industrial manufacturers with the best in water filter technology for over three decades. Our patented STiR fluidization technology has been validated in production and mathematically proven to clean 100% of the filter media during each backwash cycle. This effectiveness makes the STiR unmatched among industrial water purification systems, especially when compared to older technologies like sand, anthracite, and carbon media filters that do not completely fluidize the media during backwash and are susceptible to media fouling.
When removing suspended solids and oil, our STiR system provides double the throughput efficiency of conventional sand filters or graded mixed media filters. Under normal operating conditions, the STiR removes 95% to 99% of suspended solids and 90% to 99% of insoluble hydrocarbons, without the use of chemicals.
how stir works
As contaminants are captured and flow is restricted, a vacuum pressure builds. Once the vacuum pressure reaches its designated set point, the regeneration cycle is automatically triggered, the media is cleaned, and the contaminants are then removed. This process is verified via the visual indicating media bed sight glass located on each unit, and return of the vacuum pressure to its clean bed set point of 0 inches Hg.
Once proper vacuum pressure is reached, the filter begins the patented media cleaning/regeneration process. All flow is eliminated and the agitator becomes energized to completely stir the tank. The philosophy is that all of the filter media and contaminants captured become a homogeneous mixed slurry in the filter tank. Once mixed, process water is allowed to enter via the filter inlet, while the pump pulls the liquid containing all of the contaminants out through the backwash exit pipe. The filter media is retained in the filter during this cycle by the backwash screen, as contaminated water is flows through and is sent to upstream processing or waste handling.
engineered & Supported to meet your needs
Single filtration units are able to process 50 to 6,500 gpm each, depending on the application. Units are pre-assembled at the factory and shipped to the site, skid mounted, ready for installation. Units that have a diameter greater than 20' have filtration tanks designed in easily shipped and site assembled sections, to minimize freight and installation costs while maximizing single unit throughput.
