Performance of a Refitted Anaerobic Reactor System in Treatment of Water Hyacinth Press Juice
The main objective of the present experimental investigation was to evaluate the performance of using a refitted anaerobic reactor system to treat the water hyacinth press juice.The biogas production rate was rapidly rising from 25 L.d-1 to 54 L.d-1 in the first few start-up days,there was approximately 1332 L biogas measured by wet gas meter and 62％ of methane was detected during the experiment period.At the end of the anaerobic digestion treatment,it could be observed about 83.5％ COD,85.7％ SS and 74.1％ SS of the initial content was removed,declined from 7428 mg.L-1 to 1223 mg.L-1,from 6748 mg.L-1 to 967mg.L-1 and from 2315 mg.L-1 to 600mg.L-1,respectively.TN declined from 127.8mg.L-1 to 88.0mg.L-1 with a total loss of 31.2％.The variation of TP in the whole process was gradually declined,from 34.3mg.L-1 to 25.0mg.L-1,had total 27.1％ lost.In the whole digestion process the pH increased slowly from 6.8 to 7.8.On the basis of the experimental results obtained,it is possible to conclude that: the refitted anaerobic reactor system for water hyacinth press juice digestion was practical and effective.
