Solid-liquid separation of manure is a method to produce nutrient and dry matter rich fractions with higher volumetric methane potential than that of the original liquid manure. Centrifugation and chemical precipitation and flocculation are efficient options for such separation. Centrifugation efficiency depends on factors such as manure type, G-force, and dewatering volume, while chemical prec...
An experimental matrix consisting of reactor hydraulic retention time (HRT) and glucose loading rate was tested to understand the effect of organic loading on H2 production in chemostat reactors. In order to vary the glucose loading rate over a range of 0.5-18.9 g/h, the glucose concentration in the feed was varied from 2.5 to 10 gCOD/L under conditions where the HRT varied from 1 to 10 h (30 d...

510 Conclusions We have shown evidence for the bridging flocculation of PSL by p-LG. The change in surface charge of the PSL spheres resulting from adsorption of p-LG molecules correlates with the formation of aggregates bridged by protein molecules. To develop models of the kinetics of bridging flocculation, some measurements of aggregation as a function of time and temperature have been carri...
1. Flocculation reactions of anti-erythrocyte sera on emulsions of alcoholic extract of blood are described. 2. The reactions are markedly species-specific. 3. Besides the homologous reactions certain others-"heterogenetic"" ones-have been observed, and in this way the existence of new examples of heterogenetic antibodies has been demonstrated. 4. Group-specific substances can be extracted from...
Extracting high-purity DNA directly from soil has become essential for the study of microorganisms in environmental samples. However, many soils contain compounds that inhibit enzymes involved in manipulating DNA. In this study, chemical flocculation using multivalent cations was investigated as a potential method for eliminating soil-based inhibitors during the extraction process. The addition...
