Improve slurry quality with environmental compliance

Defoaming slurries in the face of strict environmental regulations proves challenging with the use of chemical antifoaming fluids. SlurryAirSeparator mechanical cement slurry defoamer replaces chemical antifoaming fluids to enhance mixing effectiveness and improve slurry quality while minimizing environmental impact.

The SlurryAirSeparator defoamer uses the hydrocyclone principle to separate entrained air from the cement slurry during the mixing process. By mechanically removing entrained air in the cement slurry, the system eliminates foaming problems and decreases the risk of pump cavitation problems. Cement mixing is improved, and the cement job experiences better density control and optimized mixing rates.
