Determination of absorption properties of natural sorbents under dynamic conditions

Abstract

The relevance of research on the absorption properties of sorbents is due to the need for an individual approach in the selection of filter media for wastewater treatment, depending on their chemical composition. In the presented article sorption properties of sorbents were studied under dynamic conditions. For this purpose, a laboratory-experimental installation for the treatment of natural and waste water was mounted. In the research three types of filtering loads were used: 1 - homogeneous load from activated carbon of BAU-A mark; 2 - combined load from activated carbon and zeolite with particle size of 5 mm; 3 - zeolite with fraction of 5 mm, 3 mm, and 1 mm. Among the studied samples of sorbents, zeolite loading with particle sizes of 5 mm, 3 mm, and 1 mm showed the best performance. Other types of loadings, such as activated carbon BAU-A and combined carbon loadings with zeolite were ineffective, because the sorption coefficient did not meet the MAC requirements.
