Introduction to Sludge Handling, Treatment and Disposal

AN INTRODUCTION TO SLUDGE HANDLING, TREATMENT AND DISPOSAL 1. GENERAL CONSIDERATIONS. Sludge, or residual solids, is the end product of wastewater treatment, whether biological or physical/chemical treatment. Primary sludge is from 3 to 6 percent solids. Treatment objectives are reduction of the sludge

Sludge Pumps amp; Wastewater Grinders Vogelsang USA

Entangled materials from digesters clog up sludge pumps and block mixers unless they are protected by a shredder. The XRipper wastewater grinder shreds and reduces entanglements and foreign matter like wood or plastic parts to an easy to handle size. This protects pumps from damage and clogging and ensures pipelines remain free.
