The Or-Tec Rocker^® Screw Press utilizes a central screw, a wedgewire drum or rocking multi-disc filter and variable back pressure plate to increase pressure on flocculated sludge and produce an exceptionally dry cake. With low electrical, water and polymer usage, and high solids cake and capture rates the system is very cost effective, easy to install, operate and maintain. An excellent high capacity solution for wastewater plants where babysitting equipment is not an option and reliable, high quality equipment is a must.

The Or-Tec Rocker Screw Press can be provided with all equipment required for dewatering, factory mounted, piped and wired on a single stainless steel skid. This equipment includes the sludge pump, polymer dosing system and control panel. The system features fully automated one push button startup and shutdown. Once started up the system can run unattended and can be set to shutdown automatically with no operator intervention.
