IronGEL™

By DeltaNova S.r.l.

Engineered to be field effective In our quest for high-performance and sustainable in-situ remediation, we have developed cutting-edge products incorporating nano and microparticles of ZVI (nZVI and mZVI) in engineered formulations, which are directly injected in the contaminated subsoil, forming reactive zones that effectively remove pollutants. DeltaNova’s designed cutting-edge nanoremediation solutions enhance treatment effectiveness while minimizing the costs and time needed for restoration. The reactive agents, in fact, are directly injected in the contaminated subsoil, forming reactive zones that effectively remove pollutants. The inclusion of engineered, eco-friendly biopolymers in IronGEL’s formulation allows the creation of a viscoelastic gel that exhibits shear-thinning behavior upon dilution in water. The unique formulation of IronGEL results in high colloidal stability, quick mixing, and smooth injection with wide subsurface distribution. Mixes instantly. Stays stable. One smart solution, infinite benefits Broad-spectrum reducing action with high reactivity towards contaminants ✓ Proven effectiveness in treating a wide range of persistent organic compounds and inorganic contaminants. Targets: - chlorinated ethenes - chlorinated aliphatic compounds - pesticides - PCBs - heavy metals - and many more Optimized stability and mobility Engineered biopolymers give IronGel its viscoelastic, shear-thinning properties, ensuring high colloidal stability, easy injection and broad distribution in the subsoil. Optimal for in field-application - Stable concentrated suspensions (45-50% ZVI) for easy on-site preparation. - The enhanced radius of influence (ROI=3÷7m) allows for a substantial reduction in the number of injection points Maximized coverage. Minimized disruption. Stimulation of the biodegradation The injection of IronGel enhances microbial activity and supports co-injection with organic substrates and for long-lasting biodegradation Composition: microparticles of ZVI (<10 µm) Rapid initiation of reductive process Quickly lowers aquifer REDOX potential down to -350 mV or less for effective ISCR of chlorinated solvents and redox-sensitive metals High reactivity for fast contaminant breakdown Proven and rapid dehalogenation of chlorinated solvents, treating from DNAPL hotspots to diffuse plume zones Full dechlorination and long lasting eremediation effect Validated long-term effectiveness, with over a year of field-proven results. POST INJECTION MONITORING Significant production of ethane (final product of the reductive dehalogenation process) also after 20 weeks from the injection
