摘要
This review highlights the current understanding of the aggregation phenomena of importance in Industrial Environmental Protection Technology; namely of particle aggregation in wastewater and gas emission treatment. The wastewaters and gaseous emissions from Forest Industry are our main focus. The complexity and variety of interfaces employed in chemical and biological methods of wastewater treatment and in purification of emission gases from aerosol particles is a challenge for a comparison analysis. The goals of this literature research are to delineate the most important similarities and key differences between aggregation phenomena on such different interfaces and to provide a coherent conception of environmental technology methods from the colloidal and surface science perspectives.
