REVIEW OF LATEST TECHNOLOGIES ON WASTE WATER TREATMENT

Public concern about the environmental effects of wastewater pollution has grown. Traditional wastewater treatment methods, such as chemical coagulation, adsorption, and activated sludge, have been used to address the issue, but they still face limitations, particularly in terms of high operational costs. Aerobic wastewater treatment is gaining attention as a cost-effective alternative due to its low operational and maintenance expenses. It is also readily accessible, highly effective, and capable of breaking down pollutants. This paper explores various wastewater treatment technologies for removing contaminants like halogenated hydrocarbons, heavy metals, dyes, pesticides, and herbicides, which are the primary pollutants found in wastewater.
