Case Study: Blackhawk's Anchor Pump® For Tough DNAPL Recovery

Gentle Pumping Action Eliminates DNAPL Emulsification and Pump Corrosion

BLACKHAWK ENVIRONMENTAL COMPANY'S Anchor Pump®, positive displacement piston pump, effectively cleans up and recovers Dense Non-Aqueous Phase Liquids (DNAPL). Typically DNAPL is found in 20' to 120' deep wells with DNAPL often residing in the bottom few feet or inches of the well. These viscous, heavy, sticky and corrosive liquids are difficult to successfully recover. Many types of pumps, including "Pneumatic Passive Fill Air Displacement Pumps" and "Electric Submersible Pumps" are used without much success because they do not suck liquid from the bottom of the well, corrode the pumps and emulsify the DNAPL, making the product difficult to treat once recovered.
