Fecal Coliform Decay And Regrowth Kinetics In An Anaerobic Dairy Wastewater Environment, Shufang Liu
Fecal Coliform Decay And Regrowth Kinetics In An Anaerobic Dairy Wastewater Environment, Shufang Liu
LSU Master's Theses
The kinetics of fecal coliforms (FC) decay and regrowth were analyzed under laboratory conditions using filtered dairy wastewater under anaerobic conditions. The mean specific growth rates during the regrowth phase, µr , in the batch study were 1.79, 1.46, and 1.27d-1 for initial organic carbon concentrations of 478, 235 and 127 mg/L COD, respectively. The substrate concentrations had a significant impact on the FC regrowth. A maximum specific growth rate (mmax) of 1.92 d-1, and half-saturated coefficient (ks) of 60.92mg/L were determined from these data. The mean dark FC decay rate coefficients, kd , at 35oC in the batch study …
Fecal Coliform Concentration In Surface Runoff From Pastures With Applied Dairy Manure, Alyson Kristine Bertges Hubbs
Fecal Coliform Concentration In Surface Runoff From Pastures With Applied Dairy Manure, Alyson Kristine Bertges Hubbs
LSU Master's Theses
This study examined the magnitude of release of fecal coliform indicator bacteria in surface runoff from pasture amended with dairy manure. The experiment was conducted at Southeast Research Station in Franklinton, Louisiana between March and June, 2001. The experiment was designed to compare the effects of two methods of manure application on fecal coliform release. Manure application simulating natural deposition by cattle (Treatment A) was compared to that of land application of manure as fertilizer (Treatment B). Application of inorganic fertilizer was used as the control. Each Treatment was applied to three field plots. Simulated rainfalls were conducted on plots …
