In this study, the possibility of application of agricultural lignocellulosic waste materials as adsorbents of different heavy metals ions from water was investigated. As adsorbents, wastes of widely cultivated plant cultures in our country were used. They were wheat straw, cornstalk, corn cob and soybean straw. These materials were showed as good adsorbents in most cases. But, leaching of organic matters from them during adsorption was observed. It was unfavourable. Because of that, adsorbents washed and dried. After that leaching of organic matters was significantly decreased, but also adsorption efficiencies slightly decreased, too.

The paper presents the results of a pilot study of the combined process of ozonation and filtration through biologically activated carbon to remove residual organic matter in the process of drinking water production. It was established that the application of these procedures resulted in the removal in average of 74% PB, 50% TOC, 60% of total aldehydes, and 54% PFTHM, the result being a consequence of the adsorption/biosorption processes involved.
