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...

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.

In an earlier study in rural Guatemala, 257 households that received flocculant-disinfectant to treat their drinking water had 39% less diarrhea than 257 control households. Three weeks after completion of the study, national marketing of the flocculant-disinfectant was extended into the study communities. Six months later, we assessed frequency of and characteristics associated with purchase a...

OBJECTIVE To compare the effect on prevalence of diarrhoea and mortality of household based treatment of drinking water with flocculant-disinfectant, sodium hypochlorite, and standard practices in areas with turbid water source in Africa. DESIGN Cluster randomised controlled trial over 20 weeks. SETTING Family compounds, each containing several houses, in rural western Kenya. PARTICIPANTS...

To satisfy the requirement on solid-liquid separation in high-density waste drilling mud, prepare the nano-modified polyacrylamide (PAM) flocculant for high density waste drilling mud by in-situ dispersion method, direct dispersion method and simultaneous formation method. The result showed the flocculent effect of nano-modified polyacrylamide prepared by simultaneous formation method was the b...

This study investigated the effect of heat and ethanol on fermentable yeast cells. Fermentable yeast cells (Saccharomyces cerevisiae strains and non-saccharomyces species) were subjected to varying temperature (37, 40 and 44°C) and ethanol concentration (8, 10, 14 and 18%) respectively. In the research, 55.35% of the fermentable yeasts were highly thermotolerant, moderately thermotolerant (42.8...

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...

Synthetic polymeric flocculants are used extensively for wastewater remediation, soil stabilization, and reduction in water leakage from unlined canals. Sources of highly active, inexpensive, renewable flocculants are needed to replace synthetic flocculants. High kaolin flocculant activity was documented for bovine blood (BB) and blood plasma with several anticoagulant treatments. BB serum also...
