Abstract
Conventional methods for the water treatment are characterized by numerous disadvantages, such as incomplete pollutants removal, expensive reagents, high energy needs, thecreation of toxic sludge or other waste products that require careful handling. These deficiencies were the imperative to explore new economically viable, technically easy feasible and effective wastewater treatments. Biosorption is a significant alternative to conventional systems for the removal of various organic and inorganic pollutants from industrial effluents. Researches done in this direction have contributed to the emergence of numerous biosorbents based on biomass of secondary raw materials or agro-industrial waste. The development of the biosorption processes have focuseda further research in the direction of modeling the regenerative biosorbents and new solid, porous composites for the biomass imobilization. The methods of granulation and immobilization are just some of the solutions to overcome the aforementioned shortcomings. In this sense, the paper discusses some new ceramic composites suitable for immobilization, their obtainmenttechnological processes and the features in the biosorption process. These eco-composites are of special importance for commercial exploitation of biosorbents in the treatment of industrial, municipal or other polluted waters.
