Case study on the effect continuous CO enrichment, via biogas scrubbing, has on biomass production and wastewater treatment in a high rate algal pond.

Microalgae grown in high rate algal ponds (HRAP) treating wastewater are considered a promising feed for biofuel production. Biomass productivity is often considered to be limited by carbon availability, with the addition of CO being the proposed solution. Biogas from anaerobic wastewater treatment potentially provides a cheap, co-located CO source.

MS2 coliphage and E. coli UVB inactivation rates in optically clear water: dose, dose rate and temperature dependence.

Natural ultraviolet irradiance disinfection is known to play a significant role in both natural wastewater treatment systems and drinking water disinfection processes, while the influence of ultraviolet B (UVB) delivering method on sunlight disinfection outcome is still unclear. This study aims to determine the effects of environmentally relevant temperatures, UVB doses (J m) and dose rates (W m) on the inactivation and log reduction values (LRVs) of the F-RNA coliphage MS2 and Escherichia coli in optically clear water. E.

Comparison of the treatment performance of a high rate algal pond and a facultative waste stabilisation pond operating in rural South Australia.

South Australian community wastewater management schemes (CWMS) treat wastewater using waste stabilisation ponds before disposal or reuse. This study compared the performance of a facultative pond, 6,300 m, 27.5 d theoretical hydraulic retention time (THRT), with a high rate algal pond (HRAP) operated at depths of 0.

Social Security Is Fair to All Generations: Demystifying the Trust Fund, Solvency, and the Promise to Younger Americans.

The Social Security system has come under attack for having illegitimately transferred wealth from younger generations to the Baby Boom generation. This attack is unfounded, because it fails to understand how the system was altered in order to force the Baby Boomers to finance their own benefits in retirement. Any challenges that Social Security now faces are not caused by the pay-as-you-go structure of the system but by Baby Boomers' other policy errors, especially the emergence of extreme economic inequality since 1980.
