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.
