Monitoring dan Analisis Kadar Aluminium (Al) dan Besi (Fe) pada Pengolahan Air Minum Pdam Tirtanadi Sunggal

Abstract

The research of monitoring and analysis of metal concentration Aluminium (Al) and Iron (Fe) in water sample gained from drinking water treatment of PDAM Tirtanadi Sunggal, has been made. The water sample was taken from four points, they were: Water of Belawan river, water in clarifier, water in reservoir, and wastewater. The monitoring was conducted for four months beginning from January 2009 to April 2009. The concentration of Aluminium and iron contined in the sample of water had been analyzed by using Atomic Absorbtion Spectrofotometric (AAS) in condition optimalized tool according to procedure of the metal determination. The result of monitoring and analysis of Aluminium concentration in January 2009 until April 2009 was: The water of Belawan river ranged from 0,0737 to 0,1720 ppm; water in clarifier ranged from 0,1894 to 0,2489 ppm; water in reservoar ranged from 0,1740 to 0,2095 ppm; wastewater ranged from 0,2080 to 0,2326 ppm. The concentration of iron metal: Water of Belawan river ranged from 0,1480 to 0,1775 ppm; water in clarifier ranged from 0,1935 to 0,2488 ppm; water in reservoir ranged from0,1789 to 0,2141 ppm; wastewater ranged from 0,2124 to 0,2343 ppm. The water from PDAM treatment of Tirtanadi Sunggal has complied with health standard for drinking according to the parameters of Aluminium and Iron metals in KEPMENKES RI No. 907/MENKES/VII/2002.

Telah dilakukan penelitian berupa monitoring dan analisis kadar logam-logam Aluminium (Al) dan Besi (Fe) dalam sampel air yang diperoleh dari proses pengolahan air minum PDAM Tirtanadi Sunggal. Sampel air diambil dari empat titik yaitu: Air sungaiBelawan, air di clarifier, air di reservoar dan air limbah. Pemantauan dilakukan selama empat bulan mulai bulan Januari 2009 sampai April 2009. Kadar logam Aluminium dan Besi yang terdapat dalam sampel air tersebut dianalisis dengan menggunakan alat Absorbtion Atomic Spectroscopy dengan kondisi alat dioptimasi sesuai prosedur penentuan logam-logam tersebut. Hasil monitoring dan analisis kadar logam Aluminium pada bulan Januari 2009 sampai April 2009 adalah: Air sungai Belawan berkisar antara 0,0737 s/d 0,172; air di Clarifier 0,1894 s/d 0,2489; air di Reservoar 0,1740 s/d 0,2095; Air limbah 0,2080 s/d 0,2326. Kadar logam besi: Air sungai Belawan 0,148 s/d 0,1775; air di Clarifier 0,1935 s/d 0,2488; air di Reservoar 0,1789 s/d 0,2124; air limbah 0,2124 s/d 0,2343. Air dari proses pengolahan PDAM Tirtanadi Sunggal memenuhi syarat kesehatan untuk diminum berdasarkan Parameter untuk logam Al dan Fe pada KEPMENKES RI No 907/MENKES/VII/2002.
