- What is a flocculant used for?
- Previously, mainly inorganic compounds (such as aluminum sulfate and iron chloride) were used for water and wastewater treatment, owing to their high availability and low price, but currently polymers (both synthetic and natural) are increasingly popular flocculants.
- What are coagulants flocculants in wastewater treatment?
- In wastewater treatment, coagulants and flocculants chemically enhance primary treatment to reduce suspended solids and organic loads from primary clarifiers. This stage combined with secondary treatment helps in achieving treated water quality that is easier to reuse or to meet discharge norms with minimal further treatment.
- Are plant extracts a useful flocculant?
- Coagulation/flocculation studies were carried out on water samples taken from local drinking water sources. The results show that the plant extracts effectively remove water turbidity and are disinfecting, therefore may be a potential useful flocculants in near future.
- Can chitosan be used as a flocculant?
- The amphoteric chitosan-based polymer was prepared by adding 3-chloro-2-hydroxypropyl trimethyl ammonium chloride to the Chito-CTA solution, which improves polymer solubility and increases its applicability as flocculant in water treatment [ 92 ]. Examples of novel, environmentally friendly flocculants were described by Sun and coworkers [ 95 ].
