This course is designed to extend students' understanding and develop their ability in the application of various aspects of environmental chemistry in relation to the major types of air and water pollution associated with industrial and vehicle emissions. It outlines the basic processes in bleaching and dyeing, electroplating and food processing that give rise to water pollution and applies physico-chemical techniques in controlling such pollution. It examines also combustion processes and the associated applications and limitations of the absorption, adsorption, oxidation-reduction and catalytic conversion techniques in relation to aerial emissions from furnaces and vehicles. Appropriate site visits will be arranged where possible to enhance students' ability in application.
This course introduces the principles and applications of various chemical and physio-chemical processes applicable for treatment and control of air and water pollution. It studies the processes of neutralization, oxidation-reduction, chemical precipitation, coagulation, flocculation, physical separation, absorption, adsorption, filtration, chemical disinfection, solvent extraction, fractional distillation and incineration. It also examines the applicabilities and limitations of such processes with reference to the treatment and recovery of toxic and hazardous chemical wastes. Appropriate site visits will be arranged to enhance students' ability in application.
