Excessive nutrients and heavy metals removal from diverse wastewaters using marine microalga Chlorella marina (Butcher)

摘要

Present study consists the nutrients and heavy metals removal efficacy of mobilized marine microalga Chlorella marina cells using different wastewaters viz., domestic sewage, industrial and aquaculture. Study indicated that as a result of seven days incubation in wastewater, C. marina cell concentration increased from 3x10(6) to 1.5x10(7) cells/ml and reduced 88% of nitrite, 75% of nitrate, 64% of ammonia and 51% of phosphorus in overall three different waste waters. Likewise, heavy metals such as chromium and lead were eliminated largely in the percentages of 89 and 87 respectively from aquaculture wastewater in particular.
