optimizing the flocculation of powdered Poly aluminium chloride (PAC) 2ton

in the case of advanced wastewater treatment for micropollutant removal, flocculation is often implemented in parallel to pac dosage in a simultaneous adsorption and flocculation tank. the hydraulic retention time for pac flocculation ranges between 10 and 30 min, depending on the plant influent [29] , [14] .

the essential guide to flocculants,the preparation of flocculants can be challenging and time-consuming. for example, powder and emulsion flocculants must dissolve and mature for an extended period. access to equipment such as pumps and stirring tanks can, therefore, impact the flocculant you choose. application flocculant selection for different wastewater types

polymer based flocculants: review of water purification

after treatment, the water content of the flocs generated by the hybrid flocculant was considerably lower than that of the compound and monomer flocculants, which can reduce flocculation time. the hybrid flocculant had fewer settling flocs, whereas the supernatant has more water after flocculation and a greater turbidity removal rate.

What polymers are used in flocculation?
The polymers used in flocculation can be classified into coagulants, which are highly charged cationic polyelectrolytes with molecular weights in the 50 000 to 10 6 daltons range, and flocculants, with molecular weights up to 20 × 10 6 daltons.
What are the different types of flocculants?
Flocculants are divided into three categories: (i) mineral supplements such as PAC, synthetic organic polymers, and (iii) flocculants found in nature (Renault et al., 2009 ). Interestingly, recovered lignin from pulp wastewater can be used as a flocculating agent and fuel.
Which nonionic polymeric flocculants are used in the mining industry?
PAM and polyethene oxide are two of the most prevalent nonionic polymeric flocculants used in the mining industry.
How effective are polymers as flocculants?
The effectiveness of polymers as flocculants depends on their molecular weight, the sign of their charge (e.g. anionic or cationic), and the relative charge density (for polyacrylamides this is expressed by the degree of anionicity).
