ABSTRACT:
A powered in-line blender for mixing additives to sludges or other flowable liquid/solid mixtures. The blender is particularly useful in a method of blending polymer to municipal sewage sludges to improve the dewatering characteristics, and thus improving total costs for dewatering, handling, and disposal.
