SLUDGE DRYER PRODUCES FUEL FROM WASTE

摘要

Wessex Water has bought a materials-storage and handling system from Braby (www.braby.co.uk) to expand the recycling options for sewerage sludge produced at its Avonmouth processing plant. The Braby system consists of two aluminium silos with pneumatic-transfer conveying systems, a common bagging plant to bag off material in case of over capacity, a support structure with stair access to entablature levels, all site wiring and a local control panel. If sewage sludge is dried to a concentration of 92-94%, the higher bulk density and calorific content allow it to be used as a fuel. Once the product is dried, the materials handling and storage system discharges the product into tankers.
