PISTON PUMPS REPLACE AIR LIFTS AT DEEP GASOLINE-SPILL PLUME TO RECOVER PRODUCT, NOT WATER

When a large gasoline spill in the Eastern U.S. produced a toxic plume 140 feet below surface, 11 popular-model air-lift pumps were installed in 4-inch-diameter wells to recover the product. But when the pumps brought up groundwater along with the product, the remediation engineer instead specified Blackhawk electric and pneumatic piston pumps.

The Blackhawks proved to be the only pumps that could reach the depth, pump the product without disturbing the formation (emulsification) and provide controlled drawdown and pump rates, according to the staff engineer for the environmental management and consulting engineering company contracted for the cleanup.

More methane, lower risks

Abstract

As the number of landfill gas-collection systems has grown, suboptimal methane production is a significant financial issue for many operators under contract to provide gas. Unrelated but noteworthy is the threat posed to nearby groundwater from fugitive leachate and subsurface gas migration. A third issue is the cost of providing electrical and/or pneumatic power to new or closed landfill cells, particularly at remote sites.

The Cedar Rapids/Linn County Solid Waste Agency (Agency), which serves Iowa’s second largest county, determined in 2011 that leachate was negatively impacting gas production. As an ameliorant, contracted engineers suggested reducing liquid levels in gas-collection wells using low-flow pumps and testing the viability of employing solar-powered pumping for efficiency and cost savings. The firm conducted a four-month test at a 30-acre cell at roughly 42º North latitude during the winter of 2011-2012.

As the number of landfill gas-collection systems has grown, suboptimal methane production is a significant financial issue for this farmer.

Simple & Reliable Top-Head Driver Outperforms With Choice of Power Sources

GLEN ELLYN, IL — Blackhawk Technology’s Apollo piston pumps – versatile and popular choices for landfill leachate, gas-well dewatering, condensate pump and low-flow remediation pumping – are now available with either solar-panel or AC-electric power configurations.

Both Apollo Solar and Apollo-AC pumps feature a rugged, low-draw 3/8 hp motor and simple linear-rod Scottish yoke mechanism with newly designed stuffing box and cartridge seals. As with all Blackhawk piston pumps, the driver motor, power and connections are mounted safely above the wellhead for easy installation and faster servicing at surface grade, cleanly away from the liquid being pumped.
