DRILLING WASTE TREATMENT – DEWATERING

Dewatering is the art and science of chemically enhanced centrifuge separation. Dewatering is the final step of a closed loop system and follows the separation process after shale shakers, hydrocyclones, and centrifuges. While high-speed centrifuges remove particles 2 to 3 microns and larger, dewatering can remove all colloidal particles down to clear water.

MINIMIZING DRILLING WASTE

Drilling waste minimization or reuse of resources that can become waste are key strategies in waste avoidance and a sound waste management plan. Two general approaches to waste minimization have developed. They can be called total fluid management (TFM) and environmental impact reduction (EIR).
