Typical Installation



A. C. Sipper



Geotech Solar Sipper

• The Geotech Solar Sipper is a solar powered remediation system, designed for remote applications where electrical power is either not available or not economically feasible to provide. The compact, easy to install features make this unit an industry favorite!

• Unlike other solar powered pumping systems, which use a standard bladder pump operated by an air compressor, the Solar Sipper uses a unique vacuum/pressure canister pump to recover hydrocarbons through a floating oleophilic/ hydrophobic intake filter. When the pump canister is filled, the pump reverses, pressurizes the system and pumps the recovered fluid to the surface and into a storage vessel.

• The Geotech Solar Sipper can effectively extract fluids from depths to 180 feet below ground surface and recover viscous hydrocarbons such as 90 weight oil when a fixed intake is utilized.



Dissolved Phase:• Grundfos Electric Pumps• Geotech Control Probes• Geotech Pressure Transducers• Geotech Pneumatic Pumps• Geotech Air Strippers• Oil Water Separators• Carbon Vessels• Geotech Plume Eaters

Air Strippers

LOPRO II LOPRO III



LOPRO Air Strippers• Multi stage counter-flow aeration design provides up 99.99%

removal• Vacuum induced draft provides greater efficiency and

eliminates leaking between trays• Lightweight modular polyethylene trays• Stainless steel bubble plates• Highly effective on BTEX, MTBE, and Radon• Supplied with controls for a complete system• 2 sizes available, 20 GPM and 60 GPM



Oil/Water Separator



Oil/Water Separators• Removes 99.9% of oil droplets 20 microns or larger• Compact design, high surface area• Gravity feed effluent or pump out compartment

option• Product storage tank optional• Solids storage• Removable cover for easy cleaning• Clarifiers



Geotech Plume Eater• In-Situ remediation system• Oxygen delivery system creating a density driven convectional or

re-circulation cell• Pulls the contaminated water TOWARD the top section of the

well• Air lifts groundwater above static to aid in re-injection of

oxygenated water into the subsurface• Enhances microbial growth in the aerobic bio-degradation

process• Available for 2” and 4” wells



LIQUID PHASE CARBON VESSELS



Carbon Treatment

• Liquid Phase Vessels• 100 lb up to 20,000 lb vessels available• Reactivated carbon, virgin carbon, coconut

shell media and other types of media available depending on your application

• Low pressure and high pressure units• 50 lb bags for media replacement available



Plume Eater benefits• In well air stripping• Air Sparging technology• Dissolved oxygen enhancement to accelerate bio-remediation• Groundwater recirculation-soil flushing with oxygenated

water• Pump & treat technology in a single energy efficient product• No net change in groundwater volume-No permits for water

treatment, extraction-water never leaves the subsurface.• No subsurface moving parts



Plume Eater “Rules of Thumb” for application

• Permeability & porosity of intended zone recommended to be 10-5 or greater hydraulic conductivity

• Minimum recommended water column profile is 8 feet• Dual well screen construction with 3-5 feet minimum of blank casing between top

screen and lower screen to prevent short circuiting of water re-circulation• 5-10 CFM @ 80 PSIG air source per well• pH conditions suitable for microbiological growth, IE: between pH6 and pH8• Low amount of oxygen scavengers in the water/formation, DO needs to be greater

than 2 mg/L for biological growth• Pilot test for 3-12 months to verify ROI, reduction in VOC concentrations, increased

biological growth• Collection of baseline data prior to pilot test for comparison: Geochemical &

Microcosm analytical recommended



Vapor Phase Treatment
