Laboratory investigation of filtration indicators in a gravity filtration unit filled with nano-packing

Today, the lack of drinking water has caused severe crises in many countries. One of the ways to deal with water shortages is to treat wastewater. Petrochemical industries are among the factories that produce significant wastewater. These industries cause a lot of damage to the ecosystem. The use of nanomaterials can play a significant role in the removal of wastewater pollutants. The use of nano-packing in the filtration structure has not been investigated in previous literature. In this research, a gravity filtration unit was used to treat the outlet wastewater from the Fajr petrochemical desalination unit. This unit is filled with titanium dioxide nano-packings. The results of this research show that the turbidity of the effluent discharged from the gravity filtration bed is reduced by about 39 %. This research shows that nano-packing has a significant effect on reducing total dissolved solids and organic carbon. This study shows that the amount of total dissolved solids and organic carbon in treated wastewater is equal to 1 % and 17.1 %, respectively. This research shows that the use of a gravity filtration unit has a significant role in reducing petrochemical effluent pollutants
