Abstract

Scale deposit especially calcium carbonate scale leads to economical and technical problems by blocking the flow of fluid. Various chemical or physical treatments have been proposed to decrease scale problem. Magnetic Descaler (MD) viewed to be better alternative to expensive conventional chemical treatment. The advantages of using MD include low cost, environmental friendly, flexible and requires no maintenance. However, magnetic descaler (MD) effectiveness in scale removal is still in doubt. Many studies proved MD to be as ineffective as it is proven effective. Many results are mixed between those that proved MD is effective and those that proved otherwise. This experimental study is conducted to investigate the applications of magnetic decsaler (MD) in scale control, which in particular focuses on the removal of scale. The experiment studied the effect of different MD configurations on scale removal and the effect of different flow velocity on scale removal using water as the solution. Domestic MD units were used for removing scale deposits inside a %" galvanized iron pipe. The efficiency of 4 different configurations ofMD units were measured. Its efficiency was evaluated by measuring the weight of the scale removed. Only MD with configuration 1 & 3 were able to remove 100% of calcium carbonate scale. Configuration 1 produced the best results with threshold value of 26.6427 g/min/Tesla followed by configuration 3 with threshold value of 7.6566 g/min/Tesla. The studied also demonstrated that the efficiency of MD application can be increased with increased velocity. The higher the velocity, the more efficient is MD application.
