26730, Land Application
Posted by Ananse, Wed Mar-20-02 11:29 AM
Since WW is continually coming into the plant, more microorganisms are growing. Therefore it is necessary to occasionally remove some from the plant. That "wasted" sludge is rich in organic matter. It is also rich in pathogens. One application, besides landfilling the sludge, is land application. Land application can serve several purposes: it can serve to rejuvenate land that has been stripped of nutrients and it can be used as fertilizer for fields. Advanced treated wastewater can also have novel uses.
