| Abstract | A consumer-products industrial effluent contained high phosphate and sulfatefrom the manufacturing and wastewater treatment processes, resulting in high total dissolved solids (TDS) concentration. It is believed that Chlorellasp. and Scenedesmussp. can grow inhigh-sulfatewastewater. The objective was to evaluatethe feasibility of cultivating both algae in the industrial effluent with high TDS to polish contaminants. The culture mediumswith different pH values of 3, 5, 7, and 9 and different sodium sulfate concentrations of 400, 600, 800, and 1000 mg/L were used to determine the optimum pH valuesand to evaluate the effects of high TDS onbothalgae. For both algae, the optimum pH valuewas 7.0,and high TDS affected minimally the specific growth rates but decreased considerably the biomass productivities due tohigh ionic strength. The phosphorus removal efficiency of Chlorellasp. was greater than Scenedesmussp. because of simultaneous phosphorus assimilation and calcium phosphate precipitation. The results revealed that the lower the TDS concentration in the effluent, the higher the biomass productivities of both algaewere obtained. It appears that both algae are not applicable forpolishing this effluent unless nitrogen and inorganic carbon are supplemented and the TDS is reduced. |
