Flocculant Assessment Using a Portable Batch
The reproducibility of settling tests performed on a simple, portable laboratory settling kit has been evaluated statistically and found to be acceptable. A range of partially hydrolysed polyacrylamide flocculants, having differing degrees of hydrolysis, was tested and the optimum degree of hydrolysis for Mount Edgecombe juices was found to lie between 45 and 50 %. Introduction The clarificatio...
متن کاملSpeciation stability of inorganic polymer flocculant–PACl
The speciation distribution, physico-chemical properties of coagulants, and principles for their further species transformation under various water and wastewater treatment conditions are of paramount importance in coagulation processes. In this paper, the effect of various factors on the speciation transformation of typical inorganic polymer flocculants (IPFs)–polyaluminum chloride (PACl) was ...
متن کاملCharacterization of an Exopolymeric Flocculant Produced by a Brachybacterium sp.
We evaluated the bioflocculant production potential of an Actinobacteria, which was isolated from a freshwater environment in the Eastern Cape province of South Africa. 16S rDNA nucleotide sequencing analyses revealed that the actinobacteria belongs to the Brachybacterium genus, and the sequences were deposited in the GenBank as Brachybacterium sp. UFH, with accession number HQ537131. Optimum f...
متن کاملSome Aspects of Flocculant Use in Clarification and Filtration
Clarification and filtration characteristics of some South African raw juice samples were examined in relation to flocculant usage. The influence of flocculant degree of hydrolysis on the efficiency of these processes is described. The zeta potential of the juice particles was found to modify the choice of flocculant for optimum settling and filtration.
متن کاملSome Aspects of Flocculant Use in the Phosphatation Process
The influence on impurity removal exerted by the application of flocculants in the phosflotation process has been investigated. A number of cationic flocculants are shown to enhance the removal of colour and starch. The use of flocculants did not influence the turbidity and conductivity ash of the clarified liquor. Changes in filterability and phosphate content of clear liquor resulting from th...
