Algal treatment of pulp and paper industry wastewaters in SBR systems - http://d.wanfangdata.com.cn/NSTLQK_NSTL_QK6290649.aspx
Highly colored and highly polluted pulp and paper industry wastewaters are proposed to be treated by using algae in sequential batch reactors (SBR). Results of batch studies revealed that up to 74% COD; 74% color removal could be attained in about 40days of incubation. Maximum removal efficiencies achieved were 60 to 85% for COD, 42 to 75% for color and 82 to93% for AOX for the filling periods of 4 to 12 days. For 8 days or longer filling periods, no additional reaction time was required. Results showed that, organics in the wastewater were both chlorinated and non-chlorinated; algae removed these mainly by metabolism; and chlorine cleavage from chlorinated organic molecules was more rapid than the degradation of non-chlorinated and colored organics. Adsorbed lignin on algal biomass was found to be varying between 10-20% depending on filling periodapplied
Biofixation of CO2 and Green House Gas Abatement with Microalgae - Technology Roadmap - http://moritz.botany.ut.ee/~olli/b/RepBenemann03.pdf
This Roadmap provides an expert consensus of the R&D that needs to be carried out to develop practical microalgae processes that could abate hundreds of millions of tons of fossil CO2 and other greenhouse gases. Such microalgae processes would use CO2 from power plant flue-gases or similar sources to cultivate specific microalgal species in large ponds at high solar conversion efficiencies, with the harvested biomass converted to renewable fuels to replace fossil fuels. The objective of this Roadmap is to identify R&D issues that could be resolved within five years and result in the development of practical applications within the decade.
