Abstract

The increasing industrial water consumption is one of the main contributors to the global warming phenomena. The purpose of this project is to investigate the minimum water consumption at a printed circuit board plant using the water pinch methodology. This project starts with carrying an inspection on site to identify the important sampling points for data extraction then it continues to implementing the data into three different water pinch methods and then choosing the most feasible option in order to achieve the minimum water requirements for the plant. After applying the water pinch methodology on the PCB plant case study, it was found that the WCA & SDCC methods have managed to achieve a significant reduction in the plant water requirements with 43.42% and 51.77% respectively, while the WSD have only made a 10.98% reduction. After a critical comparison based on the amount of reduction, processing times and accuracy, the WCA was chosen as the best method for the PCB plant case study. The implementation of such methods will ultimately lead to less power consumed on water treatment plants, thus less gas emissions. The water pinch analysis is a viable option to the industry environmentally and economically.
