River Water Protection Filter | Filtra-Systems
Sam Livingston Fish Hatchery
Calgary, Alberta, Canada
(1) STiR-28V (28 ft2 filter)
The Sam Livingston Fish Hatchery raises approximately 3 million fish per year and discharges 4700 gallons per day of plant wastewater, which contains fish waste, fish food, and other suspended solids into the Bow River.
The Filtra-Systems STiR industrial water filter underwent a 3-week evaluation to determine if a production scale filtration unit can reduce the daily Total Suspend Solids (TSS) load below the present limit of 22 kg/day.
Turns out, a single STiR filter reduced the daily TSS in the waste stream by a factor of 10.
This met the waste discharge requirements of the hatchery, and also protected the river from pollution. With this water filter the Bow River is now protected during all four seasons.
The Filtra-Systems STiR filter employs a dynamic backwashing method (self cleaning, minimized waste volume), which is achieved through its proprietary regeneration assembly. This allows it to provide extremely clean water, a main reason for implementation.
