Abstract: | Pengecekan kualitas air dan penentuan dosis optimum koagulan PAC (Poly
Aluminium Chloride) serta polimer kationik merupakan komponen pokok yang
diperlukan dalam penyusunan standar operasional prosedur (SOP) dalam
pengolahan air sungai Ciujung yang memiliki karakteristik tingginya nilai
kekeruhan. Pengujian menggunakan metode jar test yang mengacu pada SNI 19-
6449-2000 dengan penilaian keoptimalan dosis berdasarkan presentase efektivitas
penyisihan kekeruhan dan stabiltas pH serta TDS. Berdasarkan hasil penelitian
yang dilakukan pada variasi kekeruhan 50-60 NTU, 70-90 NTU, 100-200 NTU dan
400-600 NTU dosis PAC optimum pada rentang 90-110 ppm dan dosis 0,3-0,4 ppm
untuk penggunaan polimer kationik dengan kecepatan pengadukan lambat optimal pada 50 rpm. Pengoptimalan dosis ditunjukan dengan kemampuan menurunkan
kekeruhan air dengan efektivitas removal rata-rata di atas 90% yang termasuk pada
kategori sangat efektif dan diimbangi dengan optimalnya nilai TDS dan pH air
sesuai dengan standar baku mutu yang ditetapkan. Water quality testing and the determination of optimal doses of PAC (Poly Aluminium Chloride) and cationic polymers are essential components in the preparation of operational standard procedures (SOPs) in Ciujung river water treatment that have characteristics high of turbidity. The test was conducted using the jar test method referring to SNI 19-6449-2000 with the optimum dosage assessment based on the effectiveness of the isolation of turbidity and stability pH as well as TDS. Based on the results of the tests conducted at the variations of hardness 50-60 NTU, 70-90 NTU, 100-200 NTU and 400-600 NTU the optimal PAC dosage in the range of 90-110 ppm and the dose of 0.3-0,4 ppm for the use of cationic polymers with the optimal slow melting rate at 50 rpm. Dosage optimization is demonstrated by the ability to reduce water stiffness with an average removal effectiveness above 90% which belongs to the category of highly effective and balanced with optimal TDS and water pH values in accordance with the established quality standards |
