Water Pollution Control Using Clay Minerals and Agricultural Biomass-Based Adsorbents

Dear Colleagues

Water pollution occurs when potential pollutants from various industrial and other human activities are directly and indirectly discharged into water bodies without adequate treatment. These pollutants may be inorganic or organic contaminations, such as heavy metal ions, radioactive elements, dyes, surfactants and other hydrocarbons. Among the various separation techniques in water pollution control, adsorption is considered to be a superior technique because of its simple design, universal nature, high effectiveness, ease of operation and regeneration. When our water is polluted it is not only devastating to the environment but also to human health. Further there are various federal and state government and environmental protection agencies who strictly enforce regulations on minimizing pollutants from liquid discharge effluent streams. Therefore sustainable cost-effective development of removal techniques to alleviate such water pollution has been a challenging and demanding task for engineers, scientists, academics and researchers. In view of the importance of water quality and the environmental aspect, it is considered worthwhile to address the state-of-the-art of adsorption for the removal of water pollutants using various sustainable cost-effective alternative adsorbents. The nature and types of adsorbents are the main controlling parameters for effectiveness of the adsorption process. Therefore, the present Special Issue entitled “Water Pollution Control Using Clay Minerals and Agricultural Biomass-Based Adsorbents” aims at the publication of original research or review papers on the removal of inorganic/organic pollutants from water using various non-conventional, alternative, cost-effective adsorbents derived from natural biomass and clay minerals. The overall scope includes up-to-date developments on the current state of knowledge of clay minerals and various agricultural biomass-based adsorbents and their applications in the broad field of separation and purifications of water pollutants. Specifically, the topics of this special issue include, but are not restricted to:

• Occurrence and sources of pollutants in water and wastewaters and their implications in health/environment
• The synthesis, characteristics of biomass adsorbents, clay minerals and new emerging alternative adsorbents, composite adsorbents and their adsorptive effectiveness in water purification under various physicochemical process parameters
• Kinetics, thermodynamics and equilibrium: experimental data, novel theories, and models
• Adsorption calculations and modelling
• Continuous column process and process design: packed bed and moving bed systems, experiments and dynamic modelling
