A local pump & tank contractor teamed up with a reputable environmental consultant for a large(r) dewatering and processing contract. Process flows of 50 GPM and high VOC’s meant 600# of Granular Activated Carbon (GAC) per day, plus the labor. You do the math.
We suggested air stripping prior to GAC, with a calculated efficiency of 95%; ie. the carbon will last 20X longer. The reduced material & labor costs have MORE THAN paid for the rental / permitting / oversight / sampling for the project.
The client (as of this date) is please as more than 200,000 gallons have been pumped in April and no GAC changeouts have been required (based on samples from the primary GAC).
The tank-crew is pleased since the job is proceeding; the consultant is pleased as the on-site services are cleaner and more profitable; ReRem is pleased to add value and reason to the job.

Thursday, April 15th, 2010It’s only a decimal point..
Sunday, March 28th, 2010A 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.
