Abstract
ABSTRACT The increasing number of industrial laundry (laundry) due to the increasing human population resulted in more and more waste generated. Detergents used in the laundry industry can cause liquid waste to contain pollutants that can be harmful to the environment. Natural processing can make it easier for us to process laundry waste so it doesn't pollute the environment (water bodies). The use of natural coagulants in sewage treatment is proven to save costs, reduce the resulting precipitate, and of course is easy to decompose. Several natural ingredients are known to be used as alternative coagulants. One of the natural ingredients that can be used as a natural coagulant is shrimp shells and pork nuts (Vicia faba). This study used pig nut biocoagulants with the jar test (batch) method and continuous flow using a reactor. From the research conducted, it can be concluded that the significant decrease in COD and TSS concentrations, both batch and continuous flow in the two coagulant test samples, indicates that the two biocoagulants are considered capable of treating laundry waste with a certain concentration/dose. Although there were several test parameters that did not reach the quality standards, the percentage removal was significant enough that the two biocoagulants were considered optimal in reducing the test parameters in the waste sample. In batch processing, the greatest decrease in COD and TSS of Shrimp Shell Biocoagulant could reduce COD by 134 mg/L at a dose of 300 mg/L, 150 rpm and TSS 115.1 mg/L at a dose of 300 mg/L, 150 rpm. While the Pig Nut biocoagulant was able to remove COD by 259 mg/L at a dose of 300 mg/L, 150 rpm and TSS 129.4 mg/L at a dose of 300 mg/L, 150 rpm. Meanwhile, in continuous flow processing, the greatest decrease in COD and TSS using Shrimp Shell biocoagulant was able to remove COD of 288 mg/L at a dose of 300 mg/L, 150 rpm and TSS of 155.1 mg/L at a dose of 300 mg/L, 150 rpm. While the Pig Nut Biocoagulant was able to remove COD by 368 mg/L at a dose of 300 mg/L, 150 rpm and TSS 162.1 mg/L at a dose of 300 mg/L, 150 rpm.
