Performance Analysis of Dairy ETP: Study of Coagulant Treatments and Software-Based Modeling

Abstract

This report presents a study on the performance of a dairy effluent treatment plant (ETP) with a focus on coagulant treatments and software-based modeling using BioWin software. The study evaluates the effectiveness of different coagulants in enhancing the removal of pollutants from dairy wastewater and optimizing the treatment process. The report includes laboratory-scale coagulant treatment experiments, data collection, and analysis, and the development and validation of a BioWin model for the dairy ETP. The study found that Lime + Iron Polaroid in a ratio of 1:2 was the most effective coagulant for treating dairy effluent. By utilizing the BioWin simulation software, the following parameter values were obtained in accordance with the ECR 1997 standard: pH (6.35), TSS (24.19 mg/l), BOD5 (14.79 mg/l), and COD (145.31 mg/l). The study provides valuable insights into the operational dynamics of the ETP and suggests strategies for improving its efficiency. Additionally, the research findings suggest that Tamarind seed is a promising natural alternative to chemical coagulants for dairy wastewater treatment. However, it is important to consider the limitations associated with the small-scale nature of laboratory tests and the accuracy of simulation software, which rely on precise input parameters and assumptions.
