How do cationic polyacrylamide type flocculants compare with reverse demulsifiers?

Three cationic polyacrylamide type flocculants were paired with reverse demulsifiers to assess the synergistic separation performance. Their main differences are the active component content, molecular weight, and charge density. The same OPW with the oil content of 665 mg/L was used for evaluation.

Why is polyaluminum chloride a good coagulant for water treatment?

Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .

Can polyacrylamide & poly Aluminium chloride be used in wastewater treatment?

Field applications indicate that polyacrylamide (PAM) and poly aluminium chloride (PAC) are capable of dealing with diverse types of wastewater [4, , , , ]. The flocs formed by applying PAC are small, loose, and unstable. Yet flocs generated by cationic PAM are tight and more stable .

Is polyamine a good reverse demulsifier for o/w emulsion?

Polyamine is a highly efficient reverse demulsifier in demulsifying O/W emulsion. The combined PA and CPAM-2 could remove up to 90 % oil and 85 % suspended solids. PA-PAC exhibits comparable performance as PA and both outperform than PAC-QAS. Demulsification plays a more significant role than the flocculation in treating OPW.

Is Pac better than aluminum sulfate & aluminum chloride for removing turbidity & nom?

Moreover, the performance of synthesized PAC was also very much higher as compared with aluminum sulfate and aluminum chloride for removing turbidity and NOM from synthetic water samples. The coagulant dose and the lime required of synthesized PAC were reduced more than two folds relative to aluminum sulfate and aluminum chloride doses.

How is monomeric aluminum chloride (hexahydrate form) extracted from Ethiopian kaolinite?

The monomeric aluminum chloride (hexahydrate form) was extracted from Ethiopian kaolinite using hydrochloric acid and its purity was >98 % . The PAC samples were synthesized from extracted aluminum chloride solutions using calcium oxide (90 %, Blulux Laboratories Private Limited, India) as basification agent.
