ZVI Solutions
Terra Systems’ ZVI solutions combine emulsified vegetable oil (EVO) or quick-release carbon substrates with zero valent iron (ZVI) to support both biotic and abiotic degradation pathways. These technologies are designed to treat challenging contaminants, including chlorinated solvents and DNAPLs, by enhancing reaction pathways and improving overall treatment performance.
Product Offerings
SRS®-ZVI Product →
Combined biotic and abiotic treatment with enhanced distribution
SRS®-ZVI is a shear-thinning emulsion that combines ZVI with emulsified vegetable oil, lactate, and nutrients. This formulation supports both abiotic degradation through ZVI and sustained biological activity through long-term carbon delivery.
Capabilities include:
+ Combines ZVI with EVO, lactate, and nutrients
+ Shear-thinning properties for improved injectability and radius of influence
+ Supports both abiotic and biological degradation pathways
+ Designed for broad distribution in the subsurface
SRS®-EZVI Products
Targeted treatment for DNAPL and
high-concentration zones
SRS®-EZVI is a micelle-based EVO/ZVI technology designed to treat dense non-aqueous phase liquids (DNAPLs) and high concentrations of chlorinated solvents. The hydrophobic exterior attracts contaminants, drawing them into a reactive zone for enhanced degradation.
Capabilities include:
+ Micelle-based delivery system with encapsulated ZVI
+ Hydrophobic exterior attracts chlorinated contaminants
+ Ideal for DNAPL and high-concentration source areas
+ Supports targeted, in-place contaminant destruction
QRS™-GLY-ZVI Products →
Rapid carbon and ZVI for accelerated treatment
QRS™-GLY-ZVI combines a quick-release glycerin substrate with zero valent iron to support fast-acting biotic and abiotic degradation. This formulation is designed for sites that require immediate reducing conditions and accelerated treatment response.
Capabilities include:
+ Quick-release glycerin for rapid carbon availability
+ ZVI for abiotic degradation pathways
+ Supports fast startup of anaerobic treatment
+ Ideal for sites requiring immediate impact and shorter timelines
Built for Flexible Applications
Terra Systems’ ZVI solutions can be used independently or as part of a treatment-train strategy,
combining rapid chemical reduction with sustained biological processes. This flexibility allows for more effective treatment of complex sites and improved long-term outcomes.
