ShaleFlow™ Mobile Water Treatment System for Reuse Aaron Poon Business Developer, Veolia

Conventional Treatments for Reuse Single treatment using lamella clarifiers Commonly known as “Floc and Drop” Heavy chemical treatment Simple, gravity only separation Legacy technology that anyone can offer

Disadvantages Non-optimizable, only variable that can be adjusted is the chemical regime. Lacks flexibility across all water types seen in shale oil (may not work for all water types). No oil recovery Incomplete removal of TSS and residual bacteria

Ineffective treatment leads to long term problems. Poor water quality, pond fouling, well fouling, and odors. 2
