Abstract:
Microaeration is a stratergy applied during
anaerobic conversion to improve treatment efficicency.
The objective of this study is to investigate the effect of
microaeration on a combined effect of sulphate and
ammonia present in latex wastewater. Wastewater obtained
from skim latex processing plant contains high ammonia
content apart from high sulphate oncentration. the latex
wastewater was treated anaerobically in two sequential
anaerobic reactors with two treatment steps and the
reactors were semi continuously fed with hydraulic
retention time(hrt) of 14 days. After 7 weeks of operation
first reactor was microaerated using an oxygen permeable
polymeric membrane. during micro aeration of latex
wastewater sulphate and ammonia removed by sulphur
reducing ammonium oxidation(srao) mechanism.
Micraeration result in cod recduction enhancement by 24%
in during first treatment step.
