Discharging different kinds of wastewater and polluted waters such as domestic, industrialand agricultural wastewaters into environment, especially to surface water, can cause heavy pollution of this body sources, With regard to increasing effiuent discharge standards to the environment, high considerations should be made when selecting
proper treatment processes. Any of chemical, biological and physical treatment processes have its own advantages and disadvantages. It should be kept in mind that economical aspects are important, too. In addition, employing environmentfriendly methods for treatment is emphasized much more these days. Application of some waste products that could help in this regard, in addition to reuse ofthese waste materials, can be an advantage . Agricultural fibers are agricultural
wastes and are generated in high amounts. The majority of such materials is generated in developing countries and, since they are very cheap, they can be employed as biosorbents in water and wastewater applications . Polluted surface waters, different wastewaters and partially treated wastewater may be contaminated by heavy metals or some organic matters and these waters should be treated to reduce pollution. The results of investigations show high efficiency of agricultural fibers in heavy metal and phenol removal. In this paper, some studies conducted by the author of this article and other investigators are reviewed.
