Dewatering rates for digested sludge in lagoons
"Digested sludge lagoons were originally considered temporary sludge storage devices; however, it was found that with prolonged storage a lagoon became an effective drying unit. Since they provide one of the more economical methods of dewatering digested sludges, they are being used frequently in place of other dewatering methods. Research is expected to improve methods of design and operation and minimize the disadvantages associated with digested sludge lagoon operation."--Page 1153.
