Abstract
Wastewater contains a detergent which is a derivative of organic substances so that its accumulation causes organic diseases. Detergents contain several ingredients, namely surfactants, builders, fillers, and additives. Some of these ingredients are very harmful to the environment. Textiles also release fibers into the environment, and one of the ways is through washing in the washing machine. There are several fibers used in textile production, for example, cotton and wool as natural fibers, micro-sized synthetic fibers such as polyester, production, and nylon associated with clothing, carpets, and other textile products may inadvertently enter the aquatic environment through the wastewater of sales and sales or manufacture of synthetic fibers and represent other types of microplastics in wastewater. Various methods are used for removing microplastics so as not to address the environment. One of the research methods being developed is electrocoagulation. Electrocoagulation is an effective electrochemical approach for treating a variety of contaminated wastewater. The electrocoagulation method is widely used because of its high efficiency in dealing with pollutant removal. Electrocoagulation can be used for the removal of organic and inorganic pollutants. In this study, the electrocoagulation method was applied to use 60 microplastics with 60 minutes of contact and 5A and 10A current flow for microplastic fiber types that have polyester and polyamide groups. In this study, the efficiency was 55% - 68% for 60 minutes with a strong current of 5A and 42% - 85% for 60 minutes with a current of 10A using polyester fiber. The removal efficiency of polyamide fiber in 60 minutes with 5A current is 53% - 74% and at 10A current is 57% - 72%. Based on hypothesis testing using statistical methods, it was found that electric current, the density of microplastic and contact time had an influence in reducing the number of microplastics in the electrocoagulation process.
