Abstract :
Carbon nanotube is unique structural and ability to removal of different pollution from soil and water.Also this pore structure matter is not to made pollution soil and environmental. When pollution isdiffusion to soil is made environmental recycle water. Wastewater dairy industry is defined as the water,which is polluted by different organic or inorganic chemical compounds. Majority wastewaters comefrom start –up and shutdown operations performed in the pasteurization process, equipment and tankcleaning. The nature of dairy processing is such that a large volume of high strength effluent is dischargedfrom the factory, this wastewater is invariably high in organic material (e.g. oils and fat, dissolved sugarsand proteins, and possibly residues of additives etc.) and consequently has a high biological oxygendemand. Hence disposal of untreated dairy wastewater with high biological oxygen demandconcentrations or treatment of it at source to a satisfactory level will be very important in preventingfuture environmental pollution. The treatment of wastewater with a high degree of operational reliabilityis now in demand all over the work. At the same time, preconditions are becoming more important. Theseapply to the limitation of sludge yield, energy consumption and space consumption. The reclamation ofenergy has been demanding increasing attention. In this research, used multi walled carbon nanotubes forreduction biological and organic load (BOD5 and COD). The result indicated is good as adsorbent andredaction contamination.
