Cultivation of Chlorella Culturing with RO Brine - Primary Effluent Blended

Abstract:

The paper introduced a new idea of culturing Chlorella with combined reverse osmosis (RO) brine concentrate and primary effluent from sewage treatment plant as culture medium. This method was expected to reuse wastewater resource and lower the cost of Chlorella cultivation. The biomass of Chlorella at different temperature and different proportion of RO brine (0-90% by volume) were measured. Results showed that Chlorella had an ability to grow in RO brine blended with primary effluent. The biomass of Chlorella in 30% of RO brine blended was the most. At a low temperature of 10℃, the effect of RO brine on Chlorella biomass was obvious, high temperature (30℃) inhibited the growth of Chlorella, 20℃ was the most favorable temperature for growth.
