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.
It’s only a decimal point..

Too expensive?
January 11th, 2010When my clients change employers I usually follow. One such client, a VERY able and talented environmental engineer, switched companies and contacted ReRem for several feasibility studies for remediation design. The work was proposed and scheduled. At the last minute the management cancelled the studies citing costs.
Fast forward; this client just contacted ReRem to conduct a study at these same sites. The equipment deployed has proven ineffective, the plume is now offsite, and two years has been lost. The management must now explain the off-site and vapor-intrusion issues to an unhappy client. Significant additional capital will be required to retrofit the site with an appropriate technology.
The dollars required to provide a proper study and design is less expensive than recovering trust and reputation.
