Pengolahan Air Sumur Diploma Teknik Universitas Diponegoro Menjadi Air Domestik Dengan Menggunakan Teknologi Sand Filter Berbasis Reverse Osmosis Well Water Treatment of Diploma Engineering Diponegoro University into Domestic Water by Using Sand Filter Technology Based Reverse Osmosis

Abstract

The use of domestic water has a parameter that can be used in everyday life. To achieve quality standard parameters then used sand filter, which has been developed with the technology of Reverse Osmosis. This study aims to examine the total solids (Total Solid) method Gravimetry, hardness (Hardness) using titration methods Complexometry and Organoleptic Test. Results of analysis that has been carried out, with a variable time from 0 minute to the 45th minute taken every 15 minutes. Tools sand filter with Reverse Osmosis technology is affecting the decrease in Total Solid and hardness. For Solid analysis, from minute 0 to minute 45, each getting a yield of 0.004 mg / L, 0.0024 mg / L, 0.0004 mg / L, 0.0032 mg / L. while for analysis Hardness of minutes to 0 up to the 45th minute, respectively to get the result of 8.8 ppm, 4.8 ppm, 5.2 ppm, 3.2 ppm and from the results of organoleptic test sample initially becomes turbid clear, odor of the samples initially rotten becomes odorless
