An Evaluation of the Effectiveness of Biochars in the Treatment of Wastewater Generated From Car Wash Centers
Keywords:
Biochar, Biological wastewater, Car wash centers, Low-oxygen environment, Water treatmentAbstract
Biochar aids in water treatment by adsorbing contaminants like carbon based compounds and excess nutrients, improving water quality. It can adjust pH, reduce COD and BOD, and DO levels. Its porous structure also supports microbial growth, further aiding in the breakdown of pollutants. Overall, biochar is an effective material for reducing pollution and improving water quality.
This project report provides an in-depth analysis of the effectiveness of biochar in treating wastewater generated from car wash centers. The main focus of the study is to determine the performance of biochar in enhancing wastewater quality by analyzing key parameters, such as BOD, DO, COD, pH, and EC.
Biochar, produced from various sources such as wood, coconut shells, and corn cobs, was examined for its potential to reduce pollutants in wastewater. The study specifically focused on the capability of these materials to adjust pH levels, reduce COD and BOD concentrations, and increase DO levels. The results demonstrate the potential of biochar-based treatments to significantly enhance the quality of wastewater, making it a promising solution for managing effluents from car wash facilities.
