Cationic starch: an effective flocculating agent - ScienceDirect

Jar test results in silica suspension with addition of various grades of cationic starches as flocculants. The major mechanism of flocculation by polymers is bridging. The bridging takes place by adsorption of a polymer molecule at more than one site on a particle or at sites on different particles.

Preparation and Flocculation Performance of Polysilicate

Abstract. A composite flocculant (PSAS-CS) consisted of cationic starch (CS) and polyaluminum silicate (PSAS) was prepared and used for the flocculation of simulated water samples. The morphology and structure of PSAS-CS were characterized by X-ray diffraction, scanning electron microscopy, and infrared spectroscopy.

The efficiency of cationic starch (CS) as the flocculating agent of silica particles in the presence of different surfactants was studied. Using such techniques as UV–Vis spectroscopy, surface tensiometry and electrophoretic mobility, it was established that cationic starch is an effective flocculant of the silica particles.

Cationic starch: an effective flocculating agent - ScienceDirect

Abstract. A series of cationic starches (Cat St) have been developed by incorporating a cationic moiety N- (3-Chloro-2-hydroxypropyl) trimethyl ammonium chloride (CHPTAC) onto the backbone of starch in presence of NaOH. The cationic starches are characterized by elemental analysis, FTIR spectroscopy and intrinsic viscosity measurement.

A Comparative Study on the Flocculation of Silica and China

Abstract Flocculation is still one of the most important and efficient processes for water treatment. However, most industrial processes, such as in water treatment plants, still use huge amounts of synthetic polyelectrolytes for the flocculation process.

Flocculation and antimicrobial properties of a cationized

A dual-function cationic starch-based flocculant (St-CTA) was prepared easily. St-CTA can remove turbidity and inhibit bacteria in water simultaneously. The effect of CTA content on the dual functionality of St-CTA was studied. Charge attraction plays an important role in the flocculation and sterilization.

Cationic starch: an effective flocculant for separating algal

The resultant cationic starch flocculants and cationic polyacrylamide (CPAM), a commercial flocculant, were tested in harvesting experiments involving live algae grown in fresh water or animal manure. The harvest efficiency was affected by DS of the cationic starch, flocculant dosage, pH, and flocculation time.

Cationic starch: an effective flocculating agent [2005]

The cationic starches are characterized by elemental analysis, FTIR spectroscopy and intrinsic viscosity measurement. The flocculation characteristics of these starches have been evaluated in 0.25 wt% silica suspension by jar test. It has been found that among the four cationic starches, the one with longer CHPTAC chains shows the best performance.
