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.

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.

What is polyaluminium chlorides (PAC)?

Polyaluminium chlorides (PAC) has replaced a large part of traditional aluminous coagulants for water treatment in recent years because of low dosage, high efficiency, low cost and convenient usage.

Which reverse demulsifiers are used in oily produced water samples?

The properties of oily produced water samples collected from a SAGD plant. Three types of reverse demulsifiers were evaluated, including the compound of poly aluminium chloride and quaternary ammonium salt (PAC-QAS), polyamine (PA), and the compound of polyamine and poly aluminium chloride (PA-PAC).

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 .

What is the performance of compound flocculants composed of polyaluminum chloride and CPAM?

In the present study, the performance of compound flocculants composed of different concentrations of polyaluminum chloride (PAC) and cationic polyacrylamide (CPAM), the influencing mechanism of the flocculation process and the effects of temperature, settling time, and speed and time of stirring were investigated.
