Thermochemical pretreatment of water hyacinth for improved biomethanation

Water hyacinth was subjected to various thermochemical pretreatments and used as a substrate in anaerobic digestion for biomethanation. Results indicate that the pretreatment increased the solubility of biomass and improved gas production. Best results were obtained when water hyacinth was treated at pH 11.00 and temperature 121‡C. Severe treatment conditions showed a negative effect, especially on methanogenic bacteria caused by toxic compounds produced during treatment.
