โฆ Synopsis
In an effort to improve the anaerobic digestion of water hyacinth-cattle dung the effects of various adsorbents have been studied. A trend of enhanced gas production with high methane content and lower effluent BOD and COD, was found with increasing doses of the adsorbents gelatin, polyvinyl alcohol, powdered activated charcoal, pectin, kaolin, silica gel, aluminium powder, bentonite and talc powder.

The efficiency of recycling cattle dung, anaerobically digested cattle dung (biogas plant-effluent) and water hyacinth (Eichhornia crassipes) by culture of the earthworm Megascolex sp. was studied. The growth of the earthworms was increased by 156, 148 and 119% in soil supplemented with water hyacin
