Abstract

Nuclear magnetic resonance relaxation times ( T 1 and T 2 ) were measured for flocculated and unflocculated samples of activated sludge. The weight of water and solids in the sludge samples was found and related to T 1 to find the relative percentage of bound water. The results suggest that the amount of bound water increases as the samples become more unflocculated. The values of T 1 and T 2 also indicate that unflocculated individual particles are characterized by loose packing of shorter molecules and that the addition of larger molecules may induce flocculation.
