How effective is coagulant & flocculant?

Results showed that the most effective impact of coagulant and flocculant was the treated wastewater in Jar 5 using only 16 mg/L of PAC and 0.04 mg/L of PAM were used as coagulant and flocculant, respectively, resulting the value of the turbidity, pH, COD, BOD, and TSS was 2.00 NTU, pH 6.22, 2.00 mg/L, 5.22 mg/L, and 2.00 mg/L, respectively.

Which flocculant is used to treat kaolin suspension with polyaluminum chloride?

For example, a cellulose-based flocculant C-g-PDMC (Li et al. 2018), which was prepared by methyl acryloyl oxygen ethyl trimethyl ammonium chloride grafted to microcrystalline cellulose, was used to treat kaolin suspension with polyaluminum chloride (PAC).

Can biopolymer based flocculants be used for sludge dewatering?

Flocculation is widely used for sludge dewatering (Wang et al. 2016a), which belongs to the category of chemical conditioning pretreatment of sludge (Wei et al. 2018a). Recently, the application of biopolymer-based flocculants in the flocculation for sludge dewatering is a hot research direction.

Do polymer flocculants promote solid–liquid separation in water and wastewater treatment?

Flocculation Mechanism 3. Determination of Flocculation Efficiency and Mechanisms 4. Factors Affecting Flocculation 5. Bio-Based Polysaccharide Flocculants for Water Treatment 6. A New Approach in Obtaining Flocculants 7. Conclusions Polymer flocculants are used to promote solid–liquid separation processes in potable water and wastewater treatment.

Does polyaluminum chloride coagulate with hydrolyzed coagulants?

Coagulation with hydrolyzing coagulants has been studied thoroughly, but the coagulation behavior of pre-hydrolyzed coagulants such as polyaluminum chloride (PACl), especially the coagulation mechanisms at various coagulant dosages and pH values of raw water, has not been systemically investigated and not been well understood , .

Which flocculant is best for sludge dewatering?

In the pH range of 5–6, the carboxymethyl chitosan-graft-poly (acrylamide-methacryloxyethyltrimethyl ammonium chloride) flocculant could achieve the best efficiency on sludge dewatering. After flocculation for sludge dewatering, the moisture content was 76.26%, and the SRF was 1.09 × 10 13 m/kg (Shi et al. 2019).
