In this study, a new combined inorganic-organic flocculant (CIOF) of FeCl3 and membrane performance enhancer (MPE50) was prepared and added to an aerated submerged membrane bioreactor (SMBR). The effects of CIOF on the performance of an aerated submerged membrane bioreactor (SMBR) were evaluated. The results indicated that the SMBR with CIOF addition could remove almost 100% total phosphate whi...

A po)ysaccharide flocculant of Klebsiella pneumoniae H12 has been suggested to mediate microbe-plant interactions with the aid of Ca2' [K. Nakata et al., Biosci. BiotechnoL Biochern., 64, 459-465, 2ooOl. Here, twoway regulation of polysaccharide-mediated i"teractions between KL pneumoniae and Ruphanus sativus was studied using organic acids. Namety, 10 mM equiyatents of organic acids promoted p...

Palm Oil Mill Effluent (POME) treatment is an important issue for the minimization of pollution. POME is a highly polluting effluent containing various forms of organics and inorganic suspended solids. The coagulation flocculation process using Moringa oleifera seeds after oil extraction (MOAE) as a natural coagulant presents a viable alternative for the treatment of POME. A series of jar tests...

OBJECTIVE To study the characteristics of a bioflocculant named MBF7 produced by Penicillum strain HHE-P7 and the effects of cultivation conditions on bioflocculant production. METHODS The chemical group in the bioflocculant molecules was shown by Fourier transform infrared (FTIR) spectra, and the average molecular weight of MBF7 was estimated by gel permeation chromatography. The effects of ...

The present study was aimed at harvesting microalga, Chlorella vulgaris, by bioflocculation using seed powder of clearing nut, Strychnos potatorum. The research was essentially the prime step to yield a large biomass for utilising the cells in biodiesel production. Optimization of the parameters influencing bioflocculation was carried out statistically using RSM. The optimized conditions were 1...

New chemicals, based on the synergistic effect between inorganic polyaluminium salts and organic cationic polyelectrolytes, have been tested for the chemical optimization of a dissolved air flotation (DAF) unit, used as internal treatment of process waters in a paper mill based on 100% recovered paper. Laboratory tests have demonstrated that polyamine modifications of the aluminium salts are th...

A B S T R C TWastewater disposal to the sea in oil and gas production is an important critical part ensure continuity of process environment. Quality enhancement reduce content wastewater could be achieved by injecting chemical water separation process. Chemical reverse demulsifier base flocculant generally used for treatment disposal; however excessive injection forms flock particle that cause...
