Are flocculants the same as drilling fluids?

Interestingly, the flocculants applied are the same PHPA polymers used in drilling fluids. Flocculation is readily achieved in mineral processing applications, but residual PHPA concentrations in these slurries are exceedingly low even after dosing; contrast this to drilling fluids, with PHPA concentrations at least five orders of magnitude higher.

Does encapsulation of cutting particles based on PHPA polymers prevent flocculation?

Conclusions The effective encapsulation of cutting particles suspended in drilling fluids based on PHPA polymers severely limits (if not prevents) subsequent flocculation by dosing similar anionic flocculants.

Can ionic polymers be used as flocculants?

Anionic polymers used as flocculants can also carry cutting in exploration drilling. These polymers are expected to encapsulate particles, making flocculation unlikely. Centrifuging cuttings-laden fluids struggles to remove fines prior to fluid return. Anionic flocculants are ineffective, but nonionics are shown to induce aggregation.

Can a flocculant reduce the concentration of solids suspended in drilling fluid?

Achieving ∼ 50 % reduction in the concentration of solids suspended in the drilling fluid after centrifugation by pre-dosing with a flocculant was considered a good outcome for applications involving full-face diamond drilling, contributing to better properties of the fluid returned down the borehole.

Can cationic polyacrylamide be used for oily wastewater treatment?

Zhao C, Zheng H, Gao B, Liu Y, Zhai J, Zhang S, Xu B (2018) Ultrasound-initiated synthesis of cationic polyacrylamide for oily wastewater treatment: Enhanced interaction between the flocculant and contaminants.

What is Pam flocculant treatment technology?

The core of this treatment technology is the selection of flocculants. As an important flocculant, PAM has the advantages of low required dosage, high flocculation efficiency, high adaptability, and simple post-treatment. It is the most widely used organic synthetic flocculant, with the highest overall efficiency.
