Coupling of biochar-mediated absorption and algal-bacterial system to enhance nutrients recovery from swine wastewater.

Algal-bacterial system (ABS) used in treatment of high-strength ammonium wastewaters receives more and more attentions. In this paper, biochar-mediated absorption (BMA) and ABS were applied to recover nutrients from swine wastewater (SW) with high-strength ammonium, respectively. The results showed that the BMA could recover ammonium from the SW, which mitigated ammonia toxicity to the ABS.

Continuous cultivation of Arthrospira platensis for phycocyanin production in large-scale outdoor raceway ponds using microfiltered culture medium.

In the present study, the effect of filtrating algal culture medium for reuse by using microfiltration membranes on microalgal growth, microbiological contamination, and phycocyanin production of Arthrospira platensis was investigated. Results showed that microfiltered culture medium affected microalgal growth, microbiological contamination, and phycocyanin production of A. platensis significantly.
