Micron-Size ZVI Field Suspensions

Field suspension of ZVI powder in TASK™ Sweep Efficiency Agent  The chemistry used allows shear-thinning properties that improve its capability to be adequately distributed in the subsurface.   Tersus also provides an “activation” step after injection. When injecting ZVI in a biodegradeable polymer suspension, the ZVI reactions will not occur until the polymer degrades.  We can supply an enzyme breaker designed for fluids having a pH of 6.0 or higher.  The enzyme breaker is added to the chase water following the injection of the ZVI suspension.
