description: Wastewater from the Basic Chemistry Laboratory of FT Untirta produces wastewater   with a pH level of 1.35 and fairly high levels of TDS, TSS, COD, Fe, namely 4125 ppm,   3850 ppm, 2544.02 ppm, and 738.9 ppm. Until now, the wastewater of the Basic   Chemistry Laboratory has not been processed, while it is stored in jerry cans, then   given to third parties and requires quite a large cost. This study aims to provide an   alternative for basic chemical wastewater treatment, to determine the comparison of   the effectiveness of aluminum sulfate and Poly Aluminum Chloride (PAC) coagulants   and to obtain the optimum type and dosage. Wastewater treatment is carried out   physically and chemically, namely the aeration or no aeration process followed by   coagulation-flocculation. Before the waste water treatment process is carried out, a   dilution process is carried out (1:4). The aeration process lasted 30 minutes for each   sample, followed by the coagulation-flocculation process with Aluminum Sulfate and   PAC coagulants at doses of 30 ppm, 50 ppm, 70 ppm and 90 ppm. Coagulation stirring   process at 100 rpm and flocculation stirring at 40 rpm, then settling for 30 minutes.   Based on the research results, it can be concluded that the optimum use of aluminum   sulfate coagulant is 90 ppm with the aeration process. The removal efficiency with the   aeration process obtained TDS 95.64%, TSS 95.93%, Fe 99.99%. For the pH   parameter, there was a decrease from 7.65 to 6.74. Aluminum sulfate coagulant or   alum in this case is more effective in reducing basic chemical laboratory wastewater   parameters compared to PAC.
