There are many factors to consider when establishing a successful heat-dried biosolids program

摘要

Thermal drying has become a broadly accepted biosolids management practice in North America and Europe, and the product - heat-dried pellets - is suitable for use as a low-grade fertilizer or biofuel. However, the decision to produce heat-dried biosolids is only the beginning. Utility personnel must be familiar with their solids' characteristics so they can establish appropriate control limits to produce heat-dried biosolids that best meet market needs.
