The Effect of Basic Parameters on the Quality of Effluent Waste Water

Abstract

The effect of the shape of impellers on the wastewater treatment process is investigated in this research. Wastewater from the desalination unit of petrochemical industry is used in treatment tanks. Experiments are held with three different types of impellers in the treatment tanks and the amounts of chemical oxygen demands, biological oxygen demands.

Investigating the Performance of the Coagulation Process When Using a Combination of Zinc Oxide Nanoparticles and Ferric Polysulfate

“…This process mainly includes the identification of processes such as washing, cooling and dissolution of chemical compounds in which water is the main element and also determining the minimum amount of water required to complete the mentioned processes [57]- [69]. Reducing the flow of wastes, in potentially harmful liquid wastes such as water contaminated with oily substances that require special disposal and purification, also reduces the disposal space or the required purification energy to neutralize the wastes [70]- [86]. Cleaning the surfaces with a dry cloth, even in everyday tasks such as oiling metal parts, reduces the amount of water and residues contaminated with oily substances and increases the lifespan of many oil lubricants.In order to reduce polluted water, recycling and reuse of liquid waste is harmful, which allows industrial processes to minimize the amount of clean and healthy water used and then reduce the amount of polluted water produced.…”
