Agricultural Return Seepage Management and Their Reuse

The drainage of lands and the control and management of underground’s table land surface is one of the important problems in the enjoyment of agricultural lands and securing people’s food .The oozy waters of the drainage and the return seepage and reuse them is the one of the most important programs in the economy of using of water at this interval of time. We can divide the stages of the filtering and return seepage of agricultural oozy waters to 3 stages: physical-chemical and biological. At the stage of physiochemical, first molecules are sediment and separate then the pollution of the solution is sending out through the sticking to a solid. Other way of the sending out of volatile compounds is aeration. In the production of water with high quality, membranous processes includes of dialyze-electrodialize and reverse osmosis can loaded. Distillation and conclusion and clot making are other stages of physicochemical filtering. Chemical combination and sediment can separate harmful metals from water by increasing of PH and ions and unions exchange can be on of the stages. Finally advanced oxidation process is the last stage of biological filtering. Natural and mineral pollutions to be driven away and this stage use for determined formers such as natural compounds and production of articles of food by using of bacteria in reactor engineering systems for sending out or component’s change.
