Magic Instant Straw Activated Carbon and Ultrafilter Membrane PH and Turbidity Analysis 

Department of Petrochemical Engineering, Politeknik Kuching Sarawak Malaysia

Abstract: Water can contain dirt, minerals, chemicals and other impurities that make it smell and taste bad. Unwanted substances present in drinking water can be hazardous to health. Water can also harbor microscopic organisms and bacteria that can cause serious illness. This leads to the research and production of water filter also known as MiSACUM (Magic Instant Straw by Activated Carbon and Ultrafilter Membrane). The coconut shell is used to make the activated carbon by cleaning, and burning until it becomes charcoal which will be mixed with calcium chloride before being washed, drain, and dried in the oven. Raw water from Sarawak River (Sample A) and water flows in the drain at Politeknik Kuching Sarawak (Sample B) are collected and then filtered by using MiSACUM. Filtered water change colour from brownish/yellowish to colourless, tasteless and also become odourless. The level of pH and turbidity of the water are tested. As a result, the water filtered by MiSACUM for sample A and B, both have pH of 7.15. Meanwhile the turbidity test measured at 1 NTU and 0.5 NTU respectively. This proves that the water filtered by MiSACUM meet the standard requirement for the drinking water in terms of pH and turbidity levels.
