The Arlat TS filter screen consists of a continuous belt comprised of individual filter
elements supported by Stainless Steel shafts and rollers. As the water flows through the
filter elements the suspended solids are trapped on the face of the belt. The action of the belt
removes material from the water flow to be discharged downstream of the screen. The
integrated hook on each of the filter elements accommodates the removal of larger debris;
objects up to about 3-1/2” can be handled easily.
Due to the interlaced assembly of the filter elements on the belt shafts, the removed
screenings are effectively ejected off the face of the belt 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 over.
In comparison to a conventional climber style screen, the TS 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 TS 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:
