In Situ Chemical Oxidation

ISCO system design is an ever-evolving process.  Remington has spent nearly a decade refining this process, and is able to offer state-of-the-art injectates and delivery methods to its clients.

 

Newly Redesigned System

We’ve made some changes to the way we prepare and inject materials.  With our new equipment setup, we’ve tried to address the following goals:

Multiple Point Injection Better Materials Compatibility Improved Safety Large Capacity Small and Large Project Capability Improved Secondary Spill Containment Improved Internal Solution/Colloid/Slurry Maintenance New External Mixing Capacity and Zero Spill Point Transfer

 

Other Recent improvements:

 

Inside the injection trailer, there are noise hazards, as well as compressed air and chemical hazards present. We responded by moving all injectate mixing operations outside of the injection trailer. With this new design, the prepared fluids are transferred via dedicated external fill ports.

Material Compatibility

 

It is common for us to use the same injection system with completely different injectate compositions with little turnaround time in between.  It is our policy to maintain 100% material compatibility throughout this process.  As such, instead of mechanically decontaminating tanks between tasks, we have designed the system for complete tank and plumbing replacement.  We now maintain an inventory of identically constructed tanks, each of which is dedicated to a particular chemical solution. With the new design, all six tanks and the associated plumbing can be safely removed and replaced in a matter of minutes.

 

Spill Containment

Due to the nature of our injectate solutions, it is important to adequately control any spillage that might occur for any reason. To achieve this goal, we have mounted our 2,000 gallon tank array inside a large, custom constructed, secondary containment basin, which terminates in a holding tank.  This fluid can then be recovered and injected, or treated and released.  For  incompatible chemical combinations, the tanks can be individually isolated via spill pallets above the secondary floor containment. Also, secondary spill containment has been developed for the external mixing facilities.

In addition, the vacuum unit is made available to quickly remove any material that may migrate to the surface via fractures, old borings or adjacent injection points. We have packer plugs with two seperate designs. One is designed to plug adjacent holes or old boring points. The other is designed to plug adjacent monitoring wells when the injectate/groundwater threatens to rise to the surface.
