Now-a-days, sorption is one of the fastest growing techniques for the treatment of wastewaters, due to availability of large variety of biomaterials. A lot of experimentation has been done for finding effective biomaterials. The mechanism and effectiveness of sorption is done by comparative study of experimentation results and theoretical models. A computer tool SORPS (SORption Process Simulation) is developed by using MATLAB 7.11. This tool divides sorption process in two categories i.e. batch and column studies.
