AWI Filter
About
AWI (AquA Filter Ware Inc.) is a manufacturer specializing in granular media filtration systems for water and wastewater treatment plants. Established in 1977, the company operates from facilities in Calgary, Alberta (Canada) and Sandy, Utah (USA), with manufacturing based in the United States. AWI's flagship product is the Phoenix Underdrain System, a stainless steel filter underdrain featuring an integral air scour conduit that has been installed in over 2,600 filters worldwide. Rather than offering standard off-the-shelf products, AWI takes a custom-engineered approach, collaborating directly with water treatment plant designers, consulting engineers, and plant operators to tailor solutions to specific filtration requirements. Their product portfolio spans complete filter underdrain systems, panel upgrade systems for retrofitting existing filters, air scour systems, backwash troughs, and packaged filter systems. They also supply filter media including Puracite Filter Anthracite — a low-specific-gravity anthracite that reduces backwash water volumes — along with filter sand, granular activated carbon, and iron/manganese removal media. AWI provides technical services including filter inspections, pilot filtration studies, and operator training, serving both municipal and industrial water treatment markets across the United States, Canada, and select international locations.
