Lecture No 1: Overview of Biosolids Management: Characteristics, Processing,

Utilization, and Regulatory Considerations

The purpose of this lecture is to provide the student with an introductory

overview of biosolids management. A detailed discussion of each of these

topics will be covered in subsequent lectures. When the student completes

this series of 8 lectures, they will have the understanding of the theoretical

and practical issues of biosolids. This will enable them to participate in a

meaningful way in the preparation of a biosolids management plan for any

Wastewater Treatment Plant (WWTP) in the country.

KEY POINTS OF THE LECTURE

Biosolids management consumes a significant portion of a WWTP’s

budget and operational personnel.

Biosolids properties vary widely from plant to plant and even during

processing within the same plant.

Biosolids management has a significant public interface that is not

common to other unit processes at a WWTP.

The real options for ultimate disposal/use of biosolids are very

limited.

Biosolids have a complex set of regulatory constraints that when

understood help reinforce the important considerations of biosolids

management.

Biosolids are entering a new era, associated with energy reuse and the

renewable nature of the product.
