- Abstract:
- Several green innovations are introduced in this memoir: (a) the steel plant' iron oxide solid waste particles can be reused efficiently as a weighing agent as well as a polarization-inducing agent in a magnetic field enhanced gravity sludge thickening process; (b) quaternary ammonium compound (cationic surfactant) is an excellent organic disinfectant for sludge (biosolids) stabilization and thickener supernatant disinfection; the thickener supernatant total coliform count was reduced from 100,000,000/100 mL to 160/100 mL; the stablized biosolids met the criteria of Class A Biosolids which will be available for agricultural applications; (c) a new sludge (biosolids) stabilization process involving the use of organic disinfectant has been developed; (d) quaternary ammonium compound (cationic surfactant) is an excellent flocculant for waste clarification and sludge thickening; (e) an innovative magnetic sludge thickening process involving the use of both iron oxide particles (as weighing and polarization-inducing agent) and quaternary ammonium compound (as disinfecting and flocculating agent) has been developed; (f) the innovative sludge stabilization process and magnetic sludge thickening process are feasible for thickening both biological biosolids and chemical sludges; This memoir is a "call for research" inviting environmental researchers to investigate the proposed green innovations further.
