Abstract

Most fresh water bodies here in the Philippines are infested with mats of water hyacinth or more commonly known as water lilies. These aqueous plants are considered as nuisance that affects irrigations and other water systems. Meanwhile, researchers continue to seek for new sources of energy, as well as alternative fuel to answer the growing energy demand of society. The government explores the potentials of renewable energy that may aid in supporting the energy demand of the country. One of which is the conversion of biomass feedstock to biofuels. Studies conducted by different researchers tap the potential of water hyacinth as possible feedstock to anaerobic digester which converts biomass to biogas, as well as applications of biogas range from fuel for common household heating utilities to primary engine fuels. This study sought to develop a continuous-fed digester system that uses water hyacinth and fish rumen mixture as primary feedstock. A shredding machine was designed and fabricated to hasten the process of digestion. The developed shedder was able to process 15 kg/hr of shredded water From a preliminary experiment earlier conducted it was established that the most effective proportion of water hyacinth and fish rumen mixture is 2.2:1. The developed digester has a capacity of 8 kilogram and has a specific gas production rate of 2260.25 cc/g of volatile solids with an average loading rate of 847.4 grams volatile solids daily. Also, the average Methane (CH4) concentration of the gas produced was found to be 44.51 % while average Carbon Dioxide (CO2) content was 18.07%
