Aqua Guard® UltraClean™ – Fine Screen Wastewater Treatment | Parkson Corporation

The Aqua Guard® UltraClean™ represents the next generation of fine screen wastewater treatment. It outperforms the original design in side-by-side capture rate tests by over 50%. This superior performance comes from a series of patent-pending improvements in the “head” of the Aqua Guard UltraClean screen, each drawn from over 40 years of experience with the classic Aqua Guard® platform. Designed with the operator in mind, the Aqua Guard UltraClean also offers easier access to key areas of the screen such as the brush, which has been re-engineered to reduce routine maintenance by up to 75% over the original version. The Aqua Guard UltraClean technology is available both on new screens, and as a new “head” retrofit for existing Aqua Guard® element screens.

How the Aqua Guard UltraClean Works

The Aqua Guard UltraClean screen, a self-cleaning in-channel screening device, utilizes a unique filter element system, which automatically removes solids larger than element spacing. Aqua Guard screen filter elements form a 3-dimensional grid that ensures better solids capture rates when compared to rake bar screens that utilize single-dimensional vertical bars for solids capture. A specific configuration of filter elements is mounted on a series of parallel shafts to form an endless moving belt that collects, conveys and discharges solids for further processing or disposal. Solids contained in a wastewater flow are captured on the filter elements and carried upward on the belt assembly to discharge at the rear of the unit. Two-stage screening is achieved which results in minimal headloss. Coarse filtration occurs on the forward screen face and fine filtration on the recessed face. As the rake tip of one row of filter elements passes between the shank arm of the lower row, the elements automatically clean themselves. The unit is equipped with water sprays and a rotating brush that provides additional removal of solids.
