A role of flocculant chain flexibility in flocculation of

Flocculation is a physicochemical process in which fine solid particles in suspension are aggregated in the presence of a high molecular weight polymer. The role of the polymer (flocculant) is to simultaneously adsorb on several particles thus bridging them together to form larger flocs.

Flocculant - an overview | ScienceDirect Topics

Flocculants are the agents used to bring about flocculation. Chemical flocculants are highly effective and widely used. Inorganic flocculants or polymeric organic flocculants [1, 12, 17, 18, 24] may be used. For use in large-scale operations, as anticipated for production of microalgae biomass for fuels, a flocculant must meet certain key

role of alkalis in flocculation and viability of microalgae

ROLE OF ALKALIS IN FLOCCULATION AND VIABILITY OF MICROALGAE

flocculation at pH level of 11.3 for calcium hydroxide and KOH at 10.7 thus proving it. Using Potassium Hydroxide (KOH) as alkali, flocculation is observed at the range of (0.01 – 0.04 g) where the pH was 10.7. The clear flocculation in KOH is attained at 0.04 g of alkali. When KOH used as a flocculant 95% of flocculation efficiency was obtained.

roles of functional microbial flocculant in dyeing wastewater

Roles of functional microbial flocculant in dyeing wastewater

A functional microbial flocculant, MBF-g-P(AM-DAC), was prepared via grafting functional groups, amino group, ammonium group and acyloxy group, onto molecular chain of MBF. Preparation condition was optimized to achieve the high molecular weight and performance in the treatment of azo dyeing wastewater.

Improving the Efficiency of a Coagulation-Flocculation

The flocculation window in wastewater treatment by dual flocculation at pH 9 is displaced to higher flocculant dose (26.4 mg/L to 67.0 mg/L of flocculant). Unlike using NIPECs flocculation window, over 8.1 ppm interpolyelectrolyte complex is required to achieve approximately the same %RT compared to the optimum dose of the flocculant used in

Flocculants and tailings – Process productivity

A more promising alternative is in-pipe flocculation. Here flocculants are added at very high dosages (1-2 kg/tonne) to tailings already at underflow concentrations. When done right, further dewatering is then achieved on deposition. Even though the process remains poorly understood, its applied at a massive scale in the Canadian oil sands

polymer water treatment: how coagulants & flocculants clean water

Polymer Water Treatment: How Coagulants & Flocculants Clean Water

The next chemical reaction is called flocculation, which helps create even larger flocs or macro-flocs. In this step, a water-soluble polymer, or flocculant, helps bring together the coagulated particles to form longer and larger particle chains. As the flocculant chains become larger, they become heavier and even visible to the naked eye.

water soluble polymer flocculants: synthesis

Water Soluble Polymer Flocculants: Synthesis

Flocculants are partially soluble flocculants (e.g., polyacrylamide-grafted amylopectin). In that case, a portion of chains is lost in the GPC pre-injection filtration system. High molecular weight and bio-flocculants often experience chain scission in the GPC column, leading to invalid MWD results.
