IN STREAM POLLUTION CONTROL FOR AGRICULTURAL DRAINS WATER USING PLASTIC MEDIA

Water bodies are facing many problems in Egypt due to the direct disposal of both raw domestic and industrial wastewater depending on the stream self purification. With the increase of pollution amounts the stream self purification takes long distance and period to recover the stream that affected by the repeating disposals which made the stream polluted along its length. This study covered the use of plastic media inside stream as a low cost bioreactor packing media that increased dissolved oxygen by 48.88% decrease COD and BOD by 75.8% % & 81.4% % respectively. It is also decrease total dissolved solids and turbidity by 51.5% & 87.2% respectively which helped to minimize the distance needed for self - purification process in water bodies through a less distance than required.
