We know why technologies sometimes fail – there has been a trend in the industry to skip  the pre-design engineering prior to implementation. XDD Environmental’s treatability testing laboratory allows our clients to gather critical design information for their in and ex situ environmental remedies. Why is this helpful?

• Increased Certainty – The ability to identify undesirable outcomes (rebound) and avoid technology failures prior to design and full-scale implementation.
• Technology Selection – The flexibility to effectively evaluate multiple applicable technologies simultaneously.
• Determining Reagent Quantities – An understanding of the type and quantity of reagent required to meet your site objectives. Under-dosing can result in additional unanticipated applications, while over-dosing is the equivalent to pumping capital down a well.
• Cost Estimation – As reagent costs can make up a significant component of the full scale application costs, an understanding of the applicable reagents and costs can refine/confirm budget estimate.

Real World Example:

Many in the industry are turning to “tech support” to provide remedial designs. In this example, skipping the independent design engineering would have resulted in a final application cost that was more than five times the initial estimate.

XDD performed treatability testing to confirm reagent dosing requirements that were recommended by several product vendors for a bioremediation project.  Comparison of oxygen release products:

Comparison of oxygen release products:

• Treatability testing evaluated several oxygen release compounds (A, B, and C)
• Manufacturer’s recommended dosing was based on achieving complete degradation of target compounds
• Provided manufacturers with site specific data and requested recommended dosing
• Tested all products at maximum recommended dosage
• Select vendors recommended that the dosage estimate be confirmed via testing

Results?

• Maximum recommended dose from manufacturers reduced target compounds by only 11% to 18%
• Second and third dosing were still unable to reduce target compounds below project goals
