Treatment of Oily Wastewater Using Composite Flocculant of Polysilicate Ferro-Aluminum Sulfate – Rectorite
In this study, a novel flocculant was prepared by an inorganic polymetric flocculant (IPF) polysilicate ferroaluminum sulfate (PSFA) and rectorite (REC). The structure of the PSFA-REC composite was characterized by Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction (XRD), in order to determine the optimal temperature. The flocculation test was made at 25 , 45 and 65 , the res...
متن کاملPreparation and Study of a Composite Flocculant for Papermaking Wastewater Treatment
A high flocculation performance composite flocculant was prepared with sodium alginate, polyaluminium ferric chloride and cationic polyacrylamide. And the composite flocculant was used in papermaking wastewater treatment. Results indicated that it achieve the best flocculation performance when the raw material mass ratio was 2:1:1, the dosage of the composite flocculant was 20 mg/L, and the rem...
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 کاملsynthesis, characterization and application of polymethyl methacrylate grafted oatmeal: a potential flocculant for wastewater treatment
the studies report the synthesis of novel graft copolymer of oatmeal. polymethyl methacrylate grafting was carried out on oatmeal backbone via ‘microwave assisted’ approach. the graft copolymers were optimized by varying monomer and can concentration. the synthesized graft copolymers were characterized by intrinsic viscosity, ftir, tga, sem, elemental analysis, number average molecular weight a...
