Pengaruh Koagulan PAC dan Tawas Terhadap Surfaktan dan Kecepatan Pengendapan Flok Dalam Proses Koagulasi Flokulasi

Abstract

Surfactants are compounds that make up deterjents, which if deterjent is dumped into the river it will cause pollution. In the province of West Java, river water and receiving water bodies, based on the results of the study, showed moderate to severe pollution by wastewater containing deterjents. The results showed that the PAC coagulant and alum has a small effect on the decrease in surfactant and floc velocity settling, where the decrease in surfactant in the rainy season for PAC coagulant is 49.51% and alum coagulant 40.73%. While in the dry season the decrease in surfactant with PAC coagulant 41.06% and alum coagulant 31.10%. Then the floc velocity settling was measured to explain the correlation of surfactant decline, and the results obtained for the rainy season floc velocity settling with PAC coagulant was 0.80 cm / minute and alum was 0.27 cm / minute. Whereas in the dry season with the PAC coagulant the floc velocity settling was 0.91 cm / minute and the alum coagulant was 0.31 cm / minute. The results of quantitative regression analysis with the SPSS statistical test showed that the H0 hypothesis was accepted, that the coagulant had no effect on surfactant reduction and floc velocity settling.

Pengaruh Massa Karbon Aktif dan Konsentrasi Adsorbat dalam Penyerapan Zat Warna Metilen Blue

“…Terdapat beberapa metode untuk mengurangi pencemaran zat pewarna metilen biru diantaranya yang paling sering dilakukan yaitu adsorpsi dan koagulasi/flokulasi (Lolo et al, 2020) (Esterlita & Herlina, 2015).…”

PERBANDINGAN PENGGUNAAN TAWAS DAN PAC TERHADAP KEKERUHAN DAN pH AIR BAKU PDAM TIRTA MUSI PALEMBANG

“…Salah satu koagulan yang relatif murah dan mudah didapat, yang sering digunakan dalam pengolahan air yaitu tawas, dengan rumus molekul (Al2(SO4)3xH2O dimana x = 14,16 (Lolo et al, 2020). Namun kelemahan pada pemakaian koagulan tawas yang berlebih maka akan mengakibatkan air menjadi keruh (Alfian et al, 2017).…”

Electrocoagulation Method Using Al/Graphite Electrode for Removal Surfactant LAS (Linear Alkylbenzene Sulfonate)

“…There are various technologies used to remove surfactant pollutants from wastewater, such as adsorption (Amirmoshiri et al, 2020), coagulation and flocculation (Lolo et al, 2020), and the use of UV/H2O2 processes (Sakai et al, 2020). Electrochemical methods are becoming more competitive among the other proposed techniques due to their high efficiency and low cost.…”
