You can search for documents that cover the types of lagoon sludge and how to calculate sludge volume and the volatile portion, what are nutrients and how they are removed, how to deal with accumulated sludge in a wastewater lagoon, and many other useful guides that will help you to deliver safe and clean water to utility customers.
