Abstract
A gravity flow sludge load-out system for rapid and accurate loading-out of large volumes of treated biosolids from a wastewater dewatering plant, said system includes a plurality of hoppers 12, 14 supported by a main structure 16 having a plurality of vertical support members 20, each resting on a load cell 28, a sludge inlet at the tip of each hopper, and hydraulically controlled metering gates 40 at the bottom. A PLC 70 controls delivery of sludge from a dewatering facility, including e.g. a dewatering centrifuge 56, into the hoppers and then controls load-out of the sludge to a container truck by providing real-time monitoring of net sludge load-out and tight control of metering gates.
