Performance Evaluation of Laboratory Scale Vegetated Vermifilter for Domestic Wastewater: Case Study of Kolhapur

Earthworm bodies have been shown to act as biofilters and remove BOD, COD, TDS, and TSS through common mechanisms of uptake, biodegradation, and absorption from the body wall. Two laboratory-scale vertical vermifilters will be developed. One uses only canna indica and filter media, and the other uses canna indica and (earthworms) with the filter media. The experimental phase will last 72 hours. Various parameters such as BOD, COD, pH, turbidity, canna indica growth, bed clogging. Organic waste management is increasingly concerned due to unsustainable disposal practices. Sewage treatment facilities are designed to treat wastewater in a way that produces safe wastewater. However, one of the by-products, sewage sludge, is rich in pathogens because it is disposed of in landfills and used as fertilizer on farms. Sustainability can be achieved by composting organic matter with vermi. This includes accelerating nutrient circulation through a closed-loop system, leading waste to productive end applications. Earthworm composting and worm filtration are natural waste management processes that rely on the use of worms to convert organic waste into stable soil concentrates. We investigated the fate of filter materials and microbial communities during the vermifiltering process for a month while treating concentrated miscellaneous wastewater. Two filters are filled with 10 cm, the first layer from the bottom is coarse aggregate (size 20 mm, height 6 mm), the second layer is (size 10 mm, height 4 mm), and the third layer is charcoal (size). 25mm, height 4mm), 4th layer is sand (size 4mm, height 4mm), 5th layer is soil, last layer is freeboard.
