Pengaruh Proses Koagulasi Flokulasi Air Gambut Dengan Koagulan Biji Kacang Hijau (Vigna Radiata) Pada Surface Loading Rate (Vo) Dan Waktu Detensi (Td) Dengan Memakai Kolom Pengendap
Peat water has a brown to dark black color, this is due to the organic plant material turning into peat and the high content of dissolved organic substances (humus materiasl) in the form of humic acid and its derivatives. One method used to reduce organic substances and the color of peat water is to use the flocculation coagulation process. Coagulation and flocculation can be used to reduce turbidity, microorganisms, color, organic compounds, and so on. This research aims to analyze the settling column in order to obtain an isoremoval graph of peat water that has been coagulated and flocculated using green bean seeds and obtain the surface loading rate (Vo) and detention time (td) making it easier to calculate and determine sedimentation tanks for peat water treatment. The operating conditions varied were settling column depths of 25 cm, 50 cm, 75 cm, 100 cm, and 125 cm with sampling times for each port of 10 minutes, 20 minutes, 30 minutes, 45 minutes, and 60 minutes. The results showed that the best removal of organic substances was 93.10% and for color it was 87.83% at a settling column depth of 25 cm with a settling time of 60 minutes. he surface loading rate value obtained to produce 80% deposition is 50 m3/day-m2 m3/day-m2 with a detention time of 40 minutes.
