CYCLONIC THERMAL DRYING OF BIOSOLIDS

摘要

Biosolids have been a problem for operators of sewage treatment plants because the traditional on-site dewatering approach does not produce a market-ready product. A new system, Cyclonic Thermal Drying, is being trialled by Logan City Council to determine its potential to reduce volume, weight, odours and removal cost. A pilot trial is producing results that meet this objective as well as rapid processing, compact design and portability. Some local authorities may see these characteristics as offering advantages for particular situations though operating costs and biosolids characteristics may be limiting for some applications.
