Abstract
According to the World Water Resources Development Report of March 2018, global demand for water resources is increasing at an annual rate of 1% due to factors such as population growth, changes in economic development models, and diversification of consumption patterns. Water is certainly the greatest vital natural resource. Water supply is a basic requirement needed by living creatures and human beings. the basis of life on earth is water. third world countries and developing countries are suffering from potable water needs problems because of inadequate financial resources. Because of contaminated drinking water in developing countries, 15 million infants die each year, as well as poor hygiene and malnutrition. This paper focuses on the use of naturally occurring kaolin in batch experiments to assess its efficiency in removing organic and inorganic pollutants, as well as pathogenic microorganisms, from real municipal wastewater. The elements evaluated include COD (chemical oxygen demand), BOD (biological oxygen demand), TSS (total suspended solids), and O&G (oil and grease),. The results indicate that kaolin demonstrates effective removal efficiencies across different concentration ranges and pH levels ranging from 3 to 12. For the initial treatment, the maximum recovery efficiencies for COD, BOD, TSS, turbidity, oil & grease, and total coliform are 83%, 86%, 95%, 95%, 77%, 100%, and 99.98%, respectively.
Keywords: wastewater management, kaolin BOD, COD, TSS.
