Industrial Rotary Drum Screens Achieve Superb Solids Separation

JWC’s line of IPEC Internally Fed Rotary Drum Screens for industrial wastewater applications are designed to provide superior solids recovery from waste streams. JWC has been providing reliable and robust rotary screens globally through its IPEC brand since 1979. They have been used in a variety of food and beverage and industrial wastewater applications including beef, hog, poultry, and seafood offal, protein rendering, fruit and vegetable processing, pulp and paper production, just to name a few.

JWC offers its IFO, IFU and IFS Internally Fed Drum Screens as a family of solutions to meet the variety of unique industrial applications. All of the IPEC rotary screens are constructed with 304 stainless steel. The drum cylinder rotates horizontally on four UHMW polyethylene trunnion wheels with sealed bearings. Influent into the screens enters through a specially designed headbox that efficiently distributes the flow onto the drum to maximize throughput and minimize the required size of the screen. The drums rotate at 4-5 rpm allowing liquid to flow out while internal flights drive solids out the end of the drum. All units include a fixed external spray bar that operates only as needed to minimize water usage.

All units are customized to meet the specific needs of the application. Options can include 316 stainless steel, internal spray bars, customized controls, and variable frequency drives. The screening drum media, which includes wedge wire, perforated plate, and wire mesh is selected to optimize the processing performance of the application.

IFO Internally Fed Rotary Dum Screen
The IFO drum screen is supported on a 4” tubular frame, has a top-mounted TEFC motor and is typically applied to flume waters.

IFU Internally Fed Rotary Drum Screen
The IFU rotary drum screen is a compact uni-frame design that typically is applied to effluents containing moderate to low solid loadings.

IFS Internally Fed Rotary Drum Screen
The IFS rotary screens are a base frame-mounted drum screen that offer unique versatility that can handle high flows and/or high solids loading.
