Description
Summary:One of the water treatment process used is Actiflo system, utilized the concept of a pre-determined amount of microsand concentration to expedite flocs settling by mixing a chemical known as microsand into the treatment. A high cost in chemical due to excessive amount of microsand consumption to treat water. The need of additional microsand is due to high volume of unwanted debris being pumped from water intake plant into Water Treatment Plant (WTP), resulting frequent equipment breakdown and inefficient microsand recirculation. This leads to microsand wastage and higher maintenance cost. Pareto Diagram method is used to determine and solve higher chemical cost consumption due to frequent equipment problem. Bernoulli's Principle is used to obtain optimum mesh size of debris strainer. The strainer designed using CATIA V5 software. Data collected before and after implementing the strainer to analyze the result of microsand concentration and consumption. A comparison and analysis of chemical and maintenance cost explained using Microsoft Office Excel table and graph. The results showed that the new debris strainer design has improved by 33% of microsand cost and 80% on maintenance cost.
