Overall Objective

The study aimed to investigate the effect of biogas-aerating times under different frequencies on biogas production and the stability of the farm-scale improved HDPE biogas digester system

Specific Objectives

-        To evaluate the biogas productivity of water hyacinth at different daily mixing interval under practical conditions of the biogas digester.

-        To assess the biogas productivity of water hyacinth at different daily mixing intensity under practical conditions of the biogas digester.

Activities

-        Collecting and analyzing characteristics of water hyacinth for biogas production

-        Conducting the experiment to determine different daily mixing intensity in term of time and number of daily stirring on biogas production

-        Monitoring and evaluating biogas composition and biogas production

Outputs

Finding the effect of biogas-aerating times under different frequencies on biogas production and the stability of the farm-scale improved HDPE biogas digester system
