Pengaruh Konsentrasi Poli Aluminium Klorida (PAC) terhadap Alkalinitas dan Pembentukan Flok pada Pengolahan Air di PT Coca Cola Bottling Indonesia (CCBI)

Abstract

The Addition of coagulant in such like Poli Aluminium Chlorida (PAC) as for accelerate precipation the waste in water preparation process, because accured of decomposition absorption about small particles from surface arounded of decomposition. Already done analysis about pH value, alkalinity and turbidity of sample. Coagulation process done in flokulator with addition of Poli Aluminium Chlorida (PAC) like koagulan at concentration have variation. Have a notion that pH value like Starting material in PT. Coca – Cola Bottling Indonesia is 6, turbidity of water is 7,67 and first alkalinity is 92 mg/L. Observation result indicate that Poli Aluminium Chlorida (PAC) concentration shaping flok according to complete between 6000 – 7500 ppm with alkalinity standart between 65 – 85 mg/L.
