Effects of livestock wastewater variety and disinfectants ...

Livestock ,wastewater, could vary significantly in biodegradability and it may turn to be non-biodegradable after a long-term storage. The variety of the livestock ,wastewater, has a decisive influence on the performance of the CWs system, especially in TN elimination. In addition, the application of disinfectants UNIPRED and HYPROCLOR ED may cause serious inhibition on microbial activities and ...

Prior to reaction, the pH of the ,wastewater, was adjusted to 7.0 ± 0.2 using nitric acid. For anaerobic systems, pH 7, 10 mM sodium nitrate or sodium chloride solutions were made in an anaerobic chamber using deoxygenated ,water, (P O 2 = 0 atm). ,Wastewater, samples were deoxygenated by stirring them for at least 48 h in the anaerobic chamber.

Combined application of lime (CaCO 3) and gypsum (Valzano, Murphy, & Greene, 2001), practiced in ,acidic, dispersive soils, is useful in increasing soil pH and also reducing soil dispersivity. In alkaline soils, phytoremediation of alkalinity by growing certain plants, such as legumes, which can introduce protons in the rhizosphere, is used to reduce soil pH (Qadir et al., 2007 ).

7/5/2014, · Chlorella minutissima was co-cultured with Escherichia coli in airlift reactors under mixotrophic conditions (glucose, glycerol, and acetate substrates) to determine possible effects of bacterial contamination on algal biofuel production. It was hypothesized that E. coli would compete with C. minutissima for nutrients, displacing algal biomass.

Center for Food Safety. A new, peer-reviewed study has been released in the June 2013 Journal of Organic Systems detailing adverse effects of genetically engineered (GE) feed on pigs. Center for Food Safety has long advocated for more robust safety testing prior to introducing GE foods into the food supply. Currently, no GE safety testing is required in the U.S.
