AWI
About
AWI (Aqua West Inc.) is a US-based manufacturer of granular media filter optimization equipment, serving municipal and industrial water and wastewater treatment plants since 1978. Headquartered at 473 W Universal Circle, Sandy, Utah, with a Canadian office in Calgary, Alberta, AWI engineers and manufactures the Phoenix line of filter underdrain and backwash components, all custom-engineered to suit specific filter designs rather than offered as one-size-fits-all solutions. The Phoenix Underdrain System is installed in over 2,600 filters worldwide and features ultra-low-profile stainless steel construction with integral air scour conduits. Product lines include the Phoenix Underdrain Lateral (complete underdrain system with integral air scour, accommodating flume widths greater than 2 feet), Phoenix Underdrain Panels (for upgrading existing underdrains without full replacement), Phoenix Air Scour (integrated compressed air system for enhanced filter backwashing), and Phoenix Backwash Troughs (custom-engineered hydraulic troughs for backwash water collection). AWI also supplies granular filter media including Puracite filter anthracite (low specific gravity to reduce backwash rates), filter sand, GAC, and iron/manganese removal media. Services include on-site filter inspections, pilot filtration studies, operator training, and packaged filter system design for new installations and retrofits. All products are manufactured in the United States with guaranteed performance.
Key Products
Ultra-low profile underdrain system with integral air scour conduit made from stainless steel, custom-engineered for uniform flow distribution in granular media filters.
Panel-based underdrain system that upgrades existing filter underdrains without requiring complete replacement, reducing downtime and cost.
Air scour system integrated with the underdrain to enhance filter backwashing by introducing compressed air to fluidize and clean the filter media.
Custom-engineered troughs that collect and convey backwash water away from the filter during the backwash cycle, designed for optimal hydraulic performance.
Low specific gravity anthracite filter media that lowers required backwash rates and reduces backwash water volumes compared to conventional anthracite.
Filter sand, granular activated carbon (GAC), and iron/manganese removal media for granular media filtration systems.
On-site evaluation of filtration process condition, providing optimization recommendations for improved filter performance.
Assessment of filterability of influent water through pilot-scale testing to determine optimal media and operational parameters.
Complete new or upgraded packaged granular media filter systems including design, equipment supply, and installation support.
