Pengaruh Penambahan Larutan Ca(OH)2 pada Air Filter terhadap Peningkatan Ph Air Reservoir di PDAM Tirtanadi Instalasi Pengolahan Air Delitua

Abstract

Has been addition of a solution of Ca(OH)2 in water filter to increase pH of water reservoir treated to match the pH of drinking water standards according Regulation of the Minister of Health 492/MENKES/PER/IV/2010 which is 6.5 to 8.5. From the results obtained treatment solution amount of Ca(OH)2 is needed as much 26.325 L/sec with water flow 1755 L/sec, 22.88 L/sec solution of Ca(OH)2 with water discharge in 1760 L/sec, 28.941 L/sec solution of Ca(OH)2 with water discharge in 1754 L/sec, 22.789 L/sec solution of Ca(OH)2 with water discharge in 1753 L/sec, 31.644 L/sec solution of Ca(OH)2 with water discharge in 1758 L/sec where finally pH is 7.
