Used Aquabelt Type AB Size 4 Gravity Belt Thickener – Continuous Sludge Thickening System

Manufacturer

Ashbrook-Simon-Hartley

Product Overview

The Used Ashbrook-Simon-Hartley Aquabelt Gravity Belt Thickener, Type AB, Size 4, is a continuous sludge thickening system engineered to increase sludge solids concentration prior to mechanical dewatering. Designed for municipal and industrial wastewater treatment applications, the Aquabelt utilizes gravity drainage to efficiently remove free water from sludge, reducing downstream processing volumes and improving overall dewatering efficiency.

This unit features an approximately 3.2-meter (10.5-foot) wide by 9.425-meter (30.9-foot) long drainage belt mounted on a durable galvanized steel frame. The system includes a feed tank for uniform sludge distribution and an FRP (fiberglass reinforced plastic) exhaust hood to assist with odor and vapor containment during operation.

Previously installed in a municipal wastewater treatment facility, the thickener was removed from service following a process change rather than equipment failure. It is well suited for use ahead of belt filter presses, centrifuges, digesters, screw presses, and other sludge dewatering equipment, helping facilities reduce sludge volume and optimize downstream processing.

Note: This listing includes the gravity belt thickener, feed tank, galvanized frame, and FRP exhaust hood as described. Pumps, polymer systems, controls, instrumentation, conveyors, and ancillary equipment are included only if specifically identified.
