Testing Instrument for Water Quality and Drinking Water Using Oxidation and Electromagnetic Methods (Case Study: Local Water Company at Bangka Barat)

Abstract

Safe clean water, especially for consumption purposes, is needed by the humans. Various regulations on water safety standards have been developed and implemented by each country, including Indonesia Regulation of the Minister of Health Number 492/MENKES/PER/IV/2010 concerning Water Quality Requirements; SNI 01-3553 2006 on Drinking Water in Packaging and Government Regulation of the Republic of Indonesia Number 82/2001 on the Management of Water Quality and Control of Water Pollution. Some parameters of physics, chemistry, biology and radioactivity are the benchmarks of water security. Raw water treatment for clean water and drinking water has been done using oxidation and electromagnetic methods. Both of these methods have been tested in local water company (PDAM) at Bangka Barat which has problems with high organic content, the amount of heavy metal content Fe and Mn that exceeds the threshold above normal and high acidity level. Test results after processing show physical and chemical parameters that meet the criteria of water quality and drinking water requirements in accordance with regulations set by the government. Other important things besides meeting the health requirements are also the quality assurance of the measuring instrument used to test the physical and chemical parameters. This measurement traceable to International System of Units through Research Centre of Metrology-Indonesian Institute of Science.
