PENGOLAHAN LIMBAH DETERJEN DENGAN METODE KOAGULASI-FLOKULASI MENGGUNAKAN KOAGULAN KAPUR DAN PAC

This research is conducted to find out the effective koagulan lime or PAC in koagulasi-flokulasi process from preparation of waste material detergent product and waste material laundry, to determine optimum mass from koagulan lime or PAC in preparation of waste material detergent product and waste material laundry using koagulasi-flokulasi process and to determine maximum percent the decrease of BOD and COD in preparation of waste material detergent product and waste material laundry. In this research, we used jartest method or koagulasi-flokulasi method by using koagulan lime or PAC. Methode that used to decrease the value of BOD and COD is koagulasi. Koagulasi is mixed koagulan and stir fast 100 rpm for one minute, then with flokulasi method, it is stir slow 40 rpm for 20 minutes and sediment, it for 30 minutes. Determine optimum mass done by add good koagulan using lime or PAC 1 gr, 2 gr, 3 gr ,4 gr, 5 gr, in waste material detergent product and waste material laundry. From the various mass koagulan know that the highest decrease maximum percent of BOD and COD in koagulan kapur is 12,05% and 75% on waste material detergent product in 5 gr mass while waste material laundry is 11,57 % and 78,57% in 5 gr mass.
