Penentuan Kadar Ammonia (NH3) pada Air Baku dan Air Reservoir Wtp Mini Kelambir V di Pdam Tirtanadi secara Spektrofotometri

Abstract

Determination of Ammonia (NH3 Key Words: Ammonia, Spectrophotometry, Raw water, Reservoir water ) rate in raw water and reservoir water WTP Mini Kelambir V at PDAM Tirtanadi by spectrophotometry has been. Determination is intended to determine levels of ammonia in the raw water and reservoir water are in accordance with the water quality standards. Determination of ammonia in the raw water and reservoir water WTP Mini Kelambir V performed by first added Mineral Stabilizer, Polivynil Alcohol Dispersing Agent and Nessler reagent. Measuring ammonia rate of λ 425 nm with Spektrophotometer DR 2010 . The examination of ammonia in the raw water and the reservoir water is 0.573 mg / L in raw water and 0,020 on the reservoir water. Levels of ammonia in the raw water has exceeded the threshold of water quality standards based on the Indonesian Government Regulation 82 date of December 14, 2001 on Air Quality Standards Class I is 0.5 mg / L, so that the raw water WTP Mini Kelambir V should do further processing that can be consumed. While the levels of ammonia in the water reservoir still meet the standard Permenkes No. 492 / Menkes / Per / IV / 2010 April 19, 2010 on the condition of the quality of drinking water is 1.5 mg / L it can be consumed as drinking water
