flocculating agent
Influence of the flocculating agent in sedimentation and performance of a non flocculent strain of Zymomonas mobilis in the etha
      
It was shown that PVP behaved as a flocculating agent at lower concentrations, but behaved as a dispersing agent at higher concentrations, while SDS at any concentration behaved as a dispersing agent for kaolinite suspension.
      
The quantities of flocculating agent employed were optimized with the aid of a patented, portable flocculation and dewatering apparatus.
      
Fenugreek mucilage as a flocculating agent for sewage treatment
      
The use of fenugreek mucilage, a natural polysaccharide and a direct food additive, as a flocculating agent for removal of suspended and dissolved solids from sewage effluent has been reported.
      
This may be obtained by a flocculation process, which consists in the agglomeration of several particles or drops using as flocculating agent hydrophilic high molecular weight macromolecules.
      
Bacillus sphaericus 2362 spore sedimentation was evaluated through batch settling experiments, using tannin as the flocculating agent.
      
The sedimentation process using tannin as a flocculating agent is promising, and a spore concentrate was obtained without loss of biological activity, presenting a LC50 equal to 0.22?ppm.
      
Grafted hydroxypropyl guargum: Development, characterization and application as flocculating agent
      
In one digester a flocculating agent was used to enhance microbial aggregation and settling.
      
Finally, cultivation of cells using flocs as inoculum indicated that the cells remained viable after flocculation with usage of the optimum flocculating agent concentrations.
      
Average diameter, particle size distribution and morphological characteristics of the microbial aggregates were obtained from the flocculation/sedimentation process of the Cupriavidus?necator DSM 545 cells by the use of tannin as flocculating agent.
