Preliminary and primary head works equipment
The Arlat PS perforated belt screen uses perforated panels, combined to create a
continuous belt, to capture solids from the flow within the influent channel. The action of
the belt removes material from the water flow to be discharged down stream of the screen.
Optional integrated hooks attached to select panels accomodates the removal of larger
debris; objects up to 3-1/2" can be handled easily.
The removed screenings are effectively ejected off the face of the belt, by means of spray
nozzles, as the belt follows the formed guides around the screen frame. As the belt enters
the discharge area it becomes horizontal which allows for ease of discharge of the
material. A rotary brush is also used in this area to minimize the opportunity for any carry

In comparison to a conventional climber style screen, the PS screen is very compact and
requires little headroom. This unit is well suited for indoor or outdoor installations with
channel sizes ranging from 24” (0.6m) up to 10’ (3m) wide.

Although the majority of the screen components are manufactured from 304SS, UHMW is
widely used to significantly reduce wear, noise and replacement costs compared to
competitive machines.

A combination utilizing the Arlat PS filter screen in addition to a SDP washer/compactor
provides an unbeatable inlet works package that will provide exceptional screening as well
as a washed and compacted discharge. .
A variety of options are available to best fit your application:
· 316 Stainless frame and component construction for more corrosive installations
· Perforated panels with 1/4" and 1/8" perforatations are readily available
· Spray wash systems can be added for additional belt cleaning
· Enclosure panels with or without viewing panels
· Heat tracing for cold weather outdoor installations
· Full PLC control panels are available that can offer;
o Torque monitoring
o Fluid differential monitoring
o Speed control for the screen drive system
o Continuous mode operation during high flow periods
o Full inlet works package integration

Technical Information:
· PS Perforated panels

o 1/4" to 1/16" opening range available
· Structural frame
o ¼” 304SS plate is formed to create the side frame
o 3/8”x4”x4” 304SS angle cross members are used to stiffen the frame
o ½”x2” 304SS flat bar is rolled to create the pathway the belt follows to
remove screenings
