Parkson Aqua Guard UltraClean Screen Installation

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.

Design Parameters for the Aqua Guard UltraClean

Standard screen widths are 1.0’ to 9.0’ depending on the model, with flow rates up to 100 MGD with a single unit. Two frame styles are available for our fine screen wastewater treatment system, depending on space and channel depth requirements. Type A is a pivoting design and Type T is a stationary design. The Aqua Guard UltraClean screen can be installed at angles 60°, 75° and 85° depending on the frame and model selected. For maximum efficiency of operation, greater flow rate and higher solids removal, the recommended angle of inclination is 75°. The screen conveys solids up and out of the channel at a speed of 7ft./min. The maximum amount of debris in cubic yards per hour that can be removed from the stream is a function of model and angle. Movement of the screen can be continuous or intermittent, however, intermittent operation is recommended. This allows a mat of solids to build up on the filter-rake elements, which increases the solids capture rate.

Features & Benefits

Reduced Maintenance

Redesigned UltraClean brush
reduces maintenance by decreased solids build up, cleaning time decreased

Improved function

Dual spray wash
reduces solids loading to brush, enhances gravity removal and provides final cleaning of filter belt after brush

Improved function

Dedicated UltraClean brush motor 
optimizes brush speed for maximum solids removal and allows quick, side removal of brush

Reduced Maintenance

Side removal of UltraClean brush
reduces labor and time to remove / replace brush, reduces housekeeping after brush replacement and improves safety

Improved function

Thousands of teeth
increase the high solids carrying capacity and their polymeric blend adds to strength and memory

Improved function

Memory / sacrificial tooth design
allows for loss of teeth without any impact to solids carrying capacity (similar to a shark); *See AG Elements video below

Reduced Maintenance

Redesigned covers
improve operator access

Improved function

Brush located towards hopper center
increases amount of solids dropping directly into hopper

Improved function

3-D filter belt screening surface
provides high capture rates without blinding the screening surface, creates filter mat to improve capture rates, and reduces downstream maintenance 

Improved function

Filter mat
Filter mat allows for intermittent operation, reduces machine wear, improves capture rates, and reduces power consumption

Reduced Maintenance

Pivots out of channel
to allows for maintenance from the operating floor and emergency by-pass; No attachments to sides or bottom of channel

Reduced Maintenance

No submerged bearings 
improves maintenance as all serviceable parts can be access above the water level

Water drop with leaves
