Abstract

Household wastewater pollution caused by environmental contamination has become increasingly prevalent, especially with the excessive presence of organic materials, which come from detergents, soaps, and other chemicals. The current study seeks to investigate the efficiency of ecoenzyme made from different fruit peel mixtures in reducing BOD of laundry wastewater. Ecoenzyme was made by mixing different amounts of fruit peel wastes (2:1:10 to 6:1:10), palm sugar, and water, then fermenting it for 90 days. Analysis of the ecoenzyme was done using its sensory properties, which include acidity, and application to different concentrations of laundry wastewater to determine their BOD, pH, TDS, COD, color, and smell. Findings indicate that ecoenzyme had some favorable properties, such as an end-product having a pH of 3.6 to 4.0 with a unique acidic scent. Laundry wastewater had a BOD value of 65.78 mg/L before being treated by ecoenzyme, while it was reduced drastically to 10.6-16.3 mg/L. Maximum efficiency was obtained using a mixture ratio of 1:5 (eco-enzyme : wastewater). The results show that the fruit-based eco-enzyme has great promise as an environmentally-friendly and cost-effective technology for upgrading domestic wastewater treatment processes toward zero-waste principles.
