Abstract

Water hyacinth (WH) and primary sludge (PS) from wastewater treatment plants can be used to generate energy which could save on the fossil fuels conventionally used as source of energy. In this study, the possibility was explored to mix water hyacinth with primary sludge in different combinations for anaerobic co-digestion, so that energy can be generated as biogas and at the same time digested sludge can be used as fertilizer for agricultural applications. Co-digestion of water hyacinth and primary sludge with required amount of water (W) was carried out in 250 ml batch digesters. Pretreatment of water hyacinth was done by alkali method. Anaerobic co-digestion was carried out in mesophilic temperature range (30°C to 37°C) with different fermentation slurries of 8% total solids (TS). Co-digestion was carried for a retention period of 60 days. The gas produced was collected by the downward displacement of water, and was subsequently measured and analyzed. Fermentation slurry PS3 (mixing ratio of 4: 26.14: 69.86 for WH: PS: W) was found to be optimum, which gave the highest biogas yield of 0.35 l/gVS with composition 69.6 % CH, 25.8 % CO2, 0.8 % N and 3.8 % O. The overall results showed that blending water hyacinth with primary sludge had significant improvement on the biogas yield.
