Abstract
Laundry services have significant economic benefits for society, but can also produce waste that has the potential to harm the environment if not managed properly. Waste from the laundry process contains various pollutants such as fat and chemical compounds such as sodium tripoli phosphate. One way to reduce phosphate levels and Chemical Oxygen Demand (COD) in laundry waste is to use the principles of coagulation and flocculation.In this research, the coagulants used came from snail shells and crab shells as an alternative because chemical coagulants have a negative impact on the environment and human health. The process of making biocoagulant from snail shells involves three stages, namely deproteination, demineralization and deacetylation.This research aims to reduce three parameters of laundry waste, namely turbidity, Total Suspended Solids (TSS), and phosphate. The research results showed that biocoagulant from crab shells was more effective in reducing these three parameters compared to biocoagulant from snail shells. This is caused by a higher degree of deacetylation in crab shells, which is 84%, compared to snail shells which only reaches 72%. The high degree of deacetylation in crab shells causes its effectiveness in binding ions to be higher, so that more floc is produced.
