Pengolahan Air Sumur Menjadi Air Minum Menggunakan Sand Filter Berteknologi Reverse Osmosis dengan Disertai Analisa Penurunan Kesadahan dan Kadar Total Solid (Well Water Treatment become Drinking Water Using Sand Filter with Reverse Osmosis Technology with Hardness’ Decrease Analysis and Analysis of Total Solid Content)

Abstract

Drinking water is water through the treatment process without any processing or a qualified health and can be drunk directly. Drinking water can be produced from a variety of sources, one of the well water. Treatment of well water until it can be adequate water consumption (drinking water) is by means of filtration. Filtration is a mechanical separation process materials based on the size of different particles. Filtration is applied to separate the solid material from a liquid or a gas, for example to obtain a desired solid fraction, or to dispose of unwanted solid fraction. With this filtration process, the bad contents in the well water to be minimized. Hardness and total levels of sediment is the main one in the processing of water into drinking water. How to lower the hardness and total levels of sediment (TS) in drinking water with a filtration process using a sand filter reverse osmosis technology. In this research study on "Performance Test of Sand Filter in Well Water Treatment in DIII Chemical Engineering, University of Diponegoro into Drinking Water with Reverse Osmosis Technology (Analysis Hardness and Total Solid)". The well water is treated with the filtration process for approximately 60 minutes. Every 12 minutes a sample is taken or the outlet (water). Tested drinking water hardness and total lees, with complexometric titration and gravimetric methods. Results from this study obtained a decrease in hardness of 3%; 2.5%; 1.5%; 2.5%; 1.5%; 1.5%. As for the content of total solids (TS) is 0.2%; 0.1%; 0.2%; 0.1%; 0%; 0%. Keywords : Filtration, Sand Filter, Drinking Water
