Water is a basic necessity for human beings and animals as well as for the survival of plants. Significant industries also utilize water for processing and cleaning. Industrial wastewater generation is a major issue for the sectors, and treatment is the utmost comprehensive requirement. The role of the petrochemical is equally important in a country's growth. The petrochemical industry wastewater characteristics depict organic and inorganic matter, accessible non-biodegradable material, and total suspended solids. The nature of the wastewater generated through the petrochemical industry is slightly acidic. The pH ranges from 4.8 to 7.2 of the effluent generated in the petrochemical industry. The current study combines biological conversion processes like Up-Flow Anaerobic Sludge Blanket (UASB) and Activated Sludge Process technique to treat various parameters. pH, Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), and Suspended Solids (SS) are the essential parameters to remove up to the permissible limits. The UASB removes approximately 65-70 percent of COD, and further processing through ASP eliminates the rest of the COD, i.e., up to 95%. The reuse of treated water shall prevent the contamination of nearby water bodies. SS, TDS, and COD removal percentages are on an average of 76%, 38%, and 95% respectively. The pH of the treated water was observed 7 to 7.5.The study's main aim is to provide environmental sustainability through wastewater treatment and ultimately focus on wealth from waste.
