As an option, any
product can be upgraded to 316 Stainless Steel for an additional charge. we
has selected the highest quality wedgewire screens designed for maximum drainage. Our
PRESCREENs are built to last. Typically, the weights of GX screens are some 20-40%
more than the same size competitors screens. This is an easy means of comparing the
amount of structural material GX uses to assure long-term customer satisfaction.
For each of these units a custom sump tank can be added to fit beneath the PRESCREEN to
provide the ability to pump the screened water. These tanks are manufactured using Stainless Steel as well and include cleanouts
The Internally-fed Rotary Screen is designed for versatility and can handle high flows and/or high solids.
Typically, the IRS provides the driest solid versus the other PRESCREENs. In fact, this system can be
used for thickening sludges containing 0.5% - 3% solids to 3% - 15%, depending on the type of sludge.
The system operates by feeding the inflfluent into a headbox, which extends 2/3 the length of the drum. The
energy is dissipated as the flflow is evenly distributed onto the sidewalls of the drum. In some sense, the
IRS is like two sidehill screens facing each other. The spreading of this flflow across the length of the screen
assures proper water drainage. The thinner the layer of water, the less chance solids interfere with drain
age. Solids are retained on the screen surface as the liquid flflows radially through the openings. Splash
guards direct the liquid fifiltrate to a central drainage
area, and the solids are transported axially, by flflights,
to the open end of the drum. The design of the flflights
in conjunction with the rotation causes these solids
to turn over and release additional water. The rota
tion of the drum allows the entire screening surface
to be continuously or intermittently washed by a fifixed
external spray bar fitted.
