Figure 1: Percentage removal of all responses with different grade of magnetic cellulose Higher amount of magnetite powder compared to cellulose also reduced the flocculation efficiency.
Selection of Reagents. Four general classes of reagents selected for the investigations included, polyelectrolytes, as well as trivalent, divalent, and monovalent electrolytes. Polyelectrolyte flocculants were used because of current interest in such reagents in mineral beneficiation. Table 3 contains a list of the flocculants studied in detail.
The floccule generated during flocculation process is called flocculate, which exists in loose reticular aggregated state. Main applications of flocculant are as follows: (1) It is used as flotation flocculant that realizes selective flocculation, so the fine particles of target mineral are aggregated and then collected by a collector so that they rise, which …

Fenugreek (Trigonella foenum-graecum) and okra (Abelmoschus esculentus) were utilised as natural coagulants and flocculants respectively for the treatment of palm oil mill effluent (POME).
treatment industry are powder flocculants, emulsions, and water-based dispersion flocculants. Combined, powder and emulsion flocculants probably comprise around 98% of the market. However, the recent innovation of water-based dispersion polymers is proving to be an exciting alternative to these more traditional flocculant formats.
Chances are, if a large amount of water is being cleaned, a larger amount of flocculant is needed. The most effective dose may also change depending on the flocculant type, which is often dictated by the available charges or size of the flocculant. Additionally, the water's pH can affect the performance of a flocculant.

Section snippets Synthesis of the chitosan-based flocculant. The grafting reaction was initiated by a radical initiator, potassium persulphate. Since the deprotonated C-2 amino group in chitosan is a powerful nucleophile (pK a . ≈ 6.5) (Ashmore and Hearn, 2000), it could react with electrophilic reagents readily.. Such a reaction process is …
