A new client called inquiring about scaling the capacity of a NEEP Systems air stripper. During the discussion I discovered the issue: the designer had ASSUMED a flow-rate of 100 GPM at the loading rates from the hottest monitor well! Now, one year and $200k later the actual flow and loading are known; 15 GPM and 30% of the anticipated VOC’s. A unit with 1/8 the size will do.
ReRem recommended downgrading the air stripper to meet the site conditions. We swapped for an appropriate-sized NEEP, assisted with the mob / demob, saved the RP 90% in power and saved-face for the consultant.
Feasibility tests are inexpensive, especially compared to the electricity and efforts to backtrack and resize a system. Knowing the ACTUAL flow and loading range is the only way to size a stripper.

Sunday, March 28th, 2010Feasibility studies, or pilot-test services
Wednesday, February 4th, 2009Essential to any remedial action is a proper understanding of the site-specific geology as it related to fluid flow. Treatability studies, also known as: pilot-test, feasibility study (FS) or aquifer testing is recommended by EPA*.
Upon completion of the remedial investigation, which documents the extent and magnitude of the impact, a remedial action plan should include aquifer testing to assess appropriate technology application and establish equipment sizing. Common testing programs include: Sparging, Venting, Distance-Drawdown, Tracer, or LNAPL recovery. ReRem Equipment Corp. provides testing services for these technologies, including equipment, mobile power source, hoses & adapters, and on-site assistant. Our 54kW generator and variable frequency drives assure a viable dataset.
- Sparging: from 2 to 100 SCFM @ up to 100PSI
- Venting: 10 to 1600 SCFM @ upto 12″HG
- Pump-testing: potable or VOC impacted, including submersible pump, hoses, meters & loggers
- Vacuum Enhanced Groundwater Extraction (VEGE): constant drawdown at stepped vacuum
- Low-profile aeration: 10 to 250 GPM, ideal for pit dewatering & frac-tanks
Testing is inexpensive, especially when compared to a misdesigned remedial action plan. We are a supplement to the services of consultants / contractors / responsible parties. We are here to HELP.
