FACTORS AFFECTING LAGOON STORAGE DISINFECTION OF BIOSOLIDS
Abstract:Over the past twenty years, there has been a great deal of information collected by Tulane, Chicago and Brown and Caldwell. From this data, the lagoon storage of biosolids can be a viable niche in the disinfection scheme. This inactivation is a function of climate, nature of biosolids and exposure time. In the South, pathogen inactivation occurs within 1.5 to 2.5 years while in the North, more time is required. Other factors are the treatment of the biosolids before storage in the lagoon, the solids content of anaerobically digested biosolids stored in the lagoon and the storage of the biosolids in its own matrix and not tilled into the soil. These factors can enhance lagoon storage inactivation by 2 to 6 times for pathogen.
