What is the difference between microwave and conventional biosolids processing?
In conventional heating, the process time is limited by the rate of heat absorption by the material from the surface inward. As biosolids are a poor conductor of heat, the process time for heating is slow, with non-uniform heat distribution. The biosolids tend to be heated excessively on the surface and edges, but very randomly within the material. If a vessel must be heated first, prior to the introduction of the biosolids, even more process time, energy and labor is expended.
