Industrial Wastewater Screening Equipment

JWC Environmental has been providing industrial wastewater screening equipment for over 40 years through our IPEC screens. Our industrial screening equipment has been used in a variety of food and beverage, oil and gas, general manufacturing and industrial wastewater applications. We have the expertise and experience to design wastewater treatment equipment to meet your application's exacting needs.

Industrial Wastewater Treatment Technologies

Our designs are the result of 40 years of refinements and 500+ installations across the food, manufacturing, and oil and gas industries. Based on build quality, performance, and lifetime cost the competition doesn’t even compare.

IPEC Industrial Screening Equipment for Industrial Wastewater

JWC’s line of IPEC industrial screening equipment for industrial wastewater applications are designed to:

• Provide superior solids recovery from waste streams
• Maximize industrial wastewater pre-treatment
• Protect downstream processes
• Reduce further treatment costs

We offer three main types of screening equipment:

• Internally Fed Rotary Drum Screens
• Externally Fed Rotary Drum Screens
• Stationary Sidehill Screens

How Do Internally Fed Rotary Drum IPEC Screens Operate?

For Internally Fed Rotary Drum Screens, the influent enters a short spillway, where the energy is dissipated and the flow is evenly distributed onto the interior of the rotary screening drum. Solids are retained on the screen surface while the liquid flows radially out through the screen openings. Screened solids are transported axially by internal flights, to the open end of the rotary drum screen. The entire screening surface is intermittently washed by a fixed external spray bar.

How do Externally Fed Rotary Drum IPEC Screens operate?

For Externally Fed Rotary Drum Screens, the raw influent enters a headbox which distributes the flow evenly across the full length of the rear, upper external surface of the rotating drum. As water passes through the screen, solids are retained on the outside of the screen drum and are carried by rotation around to the front of the screen, where they are removed by a fixed doctor blade. The screened water cascades down inside the drum and falls through the bottom, creating a vigorous backwash action. This action, together with the use of internal water sprays, self-cleans the drum on every revolution.

How Do Stationary Sidehill IPEC Screens Operate?

For Stationary Sidehill Screens, the wastewater or slurry enters a headbox where hydraulic turbulence keeps solids in suspension. The wastewater overflows a distribution weir onto a steeply sloped ramp orienting the flow tangentially onto the screen surface. The liquid passes through the openings in the wedgewire to a drainage pan. The solids slide down the surface of the screen to the discharge lip.
