Analytical methods
The following parameters of Water Hyacinth and sheep waste were analyzed:
pH analysis: A glass electrode pH meter (Systronics) was used to monitor the pH of the sample.
Total Solids (TS) and total volatile solids (VS) analysis: TS were determined at 104 to constant weight
and VS were measured by the loss on ignition of the dried sample at 550
Biogas analysis: Gas chromatograph (Chemito 1000) equipped with a thermal conductivity detector was
used to analyze the biogas sample. Hydrogen was used as a carrier gas (25 ml/min) with porapak Q
column. Standard calibration gas mixture was used for calibration. The oven temperature of 40 ,
detection temperature of 80 and the detector current of 180 mA were used
