About Us

Our Company


The first Algae Sweep Automation™ unit (ASA™) was installed at Lexington's West Hickman WWTP following several years of product research and development by Mr. Ford Hall. With newly upgraded features, the ASA™ is now known as the Weir-Wolf™ and has many installations across the USA, Canada and in foreign countries.

Our Product


The Weir-Wolf™ is spring loaded with over 50 points of flexibility. It consists of industry specific brushes of various sizes which attach to the skimmer arm. All components are stainless steel. Using the pre-existing motion it removes algae and debris from the weirs, baffles, effluent spillways and launders of wastewater clarifiers and thickeners. 

Ford Hall custom designs each Weir-Wolf™ allowing for installation on circular, multi-sided, domed, covered or open clarifiers and thickeners. The Weir-Wolf™ weighs less than 150lbs and works off of the existing drive, avoiding any noticeable torque increase.
