Abstract
Production of biogas from fresh water hyacinth in the form of slurry w as studied in a semi-continuous mode of operation by anaerobic digesti on. Data were analysed using the Chen and Hashimoto model. Kinetic con stants mu(m) and K were determined and found to be, on average, 0.125 day(-1) and 0.355 g l(-1) respectively. Computed values of gas product ivity fitted well with the observed values. Productivity increased wit h loading rate. Reaction rate decreased with retention time. The minim um substrate concentration remaining undigested increased with influen t feed concentration.
