CHARACTERIZATION OF SLUDGE "Sludge" is a generic term for the residue that results from pulp and papermaking. To better understand its properties, it is nec-essary to review how it is formed. Generally, it is the solid resi-due recovered from the wastewater stream of the pulping and papermaking process (Fig. 2). Sludge is produced at two steps
In systems treating mixed domestic and industrial wastes, only TIN and ortho-phosphorus should be used to calculate nutrient availability. Organically combined nitrogen and phosphorus (Kjeldahl nitrogen and total phosphorus) may not be hydrolyzed fast enough by the microorganisms in the activated sludge to keep pace with BOD use.
