Technical Bulletin No. 0225: Surface Properties of Hydrogels Resulting from Treatment of Pulp and Paper
Attached is a copy of the second report on hydro-gel studies, supported at the Institute of Surface Chemistry at Lehigh University by NCASI, designated as Technical Bulletin No. 225. Some of the colloidal characteristics of sludges obtained in the treatment of pulp and paper mill wastes were determined, and those of greatest significance selected for further study.
