Effectiveness of Algae Plants (Hydrilla Verticillata) and Water Hyacinth (Eichhornia Crassipes) as Phytoremediation for Laundry Liquid Waste Detergent Processing

Efektivitas Tanaman Alga (Hydrilla Verticillata) Dan Eceng Gondok (Eichhornia Crassipes) Sebagai Fitoremediasi Pengolahan Detergen Limbah Cair Laundry

Abstract

This study aims to test the effectiveness of algae (Hydrilla verticillata) and water hyacinth (Eichhornia crassipes) as phytoremediation media in the treatment of laundry wastewater containing detergent. The study was conducted by measuring the parameters of Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) in wastewater for 7 days of treatment. The results showed that water hyacinth plants were more effective in reducing BOD and COD levels compared to algae plants. On the 3rd day, water hyacinth reduced BOD by 42.0 mg/L and COD by 83.8 mg/L, while algae only reduced BOD by 21.0 mg/L and COD by 43.5 mg/L. In conclusion, water hyacinth is more effective as a phytoremediation medium than algae for the treatment of laundry wastewater
