  • Growing algae spread over open water surface of water hyacinth system the leaves of hyacinth prevented the passage of sunlight through the water surface. The objectives of this study were to investigate the effects of the algae growth on the effluent of water hyacinth wastewater treatment systems operated with the variation of an organic loading rate between 190 to 550 kg COD/ha.day. The effluent from the system contained algae was discharged for about 2-3 weeks from the beginning of experimental operation of water hyacinth systems. BOD and 55 concentration of effluents during algae growthing periods were higher than those during the period of algae control. But nitrogen and phosphrous romoval efficiencies during in algae growthing periods were slighty higher than those during the period of algae control.
