Bioadsorption is the future for industrial waste water treatment. Utilization of inexpensive products to recover and reuse toxic materials is one of the ultimate objectives of environmental engineering solutions. Usage of 'synthetic' products may enhance the over head expendiutures of a waste remediation project which in turn will discourage its applications. This is significantly applicable in developing nations that inherit 'shoe string' budgets to solve their waste abatement problems. The author has attempted to demonstrate that natural waste products such as fish scales can be effectively utilized for this purpose. The book elucidates the path required to proceed from laboratory bench scale tests to 'scale up' models for proper implementation of the biosorption process. It also incorporates the fundamentals of physical sciences to justify appropriate numerical models for further research and development.
