Biosolids Management: An Environmentally
for Managing Sewage Treatment Plant Sludge
An Introductory Guide To Decision-Makers
||Treated sludge, known as biosolids, is widely produced in many countries.
Once treated properly, sludge has important economic and environmental value due
to its high concentration of organic nutrients, which make it valuable for use
as fertiliser in agriculture or other practices. This booklet gives a general
overview of the wastewater treatment process, as well as of the production of
biosolids and their utilisation in agriculture. It should help decision-makers
who are considering this environmentally sound technological approach to solving
the problem of sludge disposal.
