Johnson Screens New Generation Contra Shear rotary drum screen
Johnson Screens New Generation Contra Shear (rotary drum screen) has been reengineered to provide operational cost savings through low-maintenance requirements, improved solids separation and dewatering.
Chain drives have been replaced with external rack and pinion drive mounted on the clean side, sealed-for-life bearings, and lubrication is not required anymore. Trommel wheels have been replaced with jockey wheels, which can now be changed over in situ in less than 20 min. Constructed from stainless steel, the rotary drum screen has virtually no wearing parts.
The new generation solid separation and dewatering has improved higher flow rates through the drum screens providing up to 30% reduction in BOD/COD, up to 25% reduction in SS and up to 15% reduction in TKN.
Options include CIP (clean-in-place), 304, 316, 2205 and 2507 stainless steel, electrical control panel, PLC Control Panel (Allen Bradley) and food-grade sealed-for-life bearings.
