Technological Innovation and Pioneering.

SGW Services maintains a constant training and technical updating program for all of its collaborators. The culture of sharing knowledge and significant investment in internal, external and international qualification, updating and new technologies courses guarantee that the team is always up-to-date with respect to procedures and technologies being used in the most developed countries, and ready to meet all the challenges that each project presents.

In the IT area, SGW Services is the pioneer in implementing in Brazil the use of the VSP (Visual Sample Plan) software, developed by the EPA – American environmental agency – and widely used in the USA for scientific calculation of multi-increment soil and groundwater samples.

CAD and GIS platforms and solutions for mathematical modeling and graphical design are also used. A geo-referenced environmental database system is in the implantation phase, which will permit the real-time management, consultation and assessment of projects information.

SGW Services was the pioneer in Brazil in using in remediation projects products especially developed for remediation of specific compounds of concern, with innovative technologies in the biotechnology area for remediation of highly hazardous compounds persistent in the environment. The company maintains close scientific collaboration with the American Adventus Group, offering crucial technical information for the development of efficient products under Brazilian climate and hydro-geological conditions. In return, the Adventus Group provides support for the SGW Services team in the conception of bioremediation projects with the best cost-efficiency.

The products that may be used in the SGW Services remediation projects are:

Reductive DARAMEND™ and aerobic TERRAMEND™.

They are products used for in-situ and ex-situ treatment of soil, muck and sediment impacted by chlorinated solvents, pesticides, herbicides, explosives, heavy metals (stabilization), nitrates and petroleum hydrocarbons. DARAMEND has been successfully used in the remediation of more than 3,600,000 tons of soil impacted by contaminants with difficult degradation, including sites at military facilities, besides a variety of industrial facilities.

EHC®

The patented EHC® uses the principle of in-situ chemical reduction (ISCR), which promotes extremely reductive environments (-600 mV) that destabilize and degrade the most persistent compounds, such as chlorinated solvents, pesticides, herbicides and explosives. Only the ISCR technology combines the force of biological and chemical processes that employ zero valent iron (ZVI) and carbon source. There are a variety of construction methods for application of EHC, such as direct injection, hydraulic fracturing, pneumatic fracturing, PRBs (Permeable Reactive Barriers), trenches, in addition to mixing directly into the soil.

EHC-M®

EHC-M® enables treatment of highly toxic heavy metals with persistence in the environment. EHC-M has the advantage of not mobilizing Arsenic and other heavy metals, a problem commonly found in the use of carbon sources such as oils, molasses, lactates and other sources of hydrogen.

EHC-O®

An Oxygen Releasing Compound, which supplies oxygen and nutrients in a controlled manner, to accelerate the aerobic bioremediation of petroleum hydrocarbons, PAHs (Polycyclic Aromatic Hydrocarbons), phthalates, MTBE (Methyl Tertiary Butyl Ether), and some chlorinated hydrocarbons such as Pentachlorophenol (PCP). It rapidly eliminates contaminants, guaranteeing a significant cost reduction in relation to other oxygen releasers available on the market, which are mostly high cost, low scientific quality and with deficient technical support for clients. Available as O-Sox™ and reusable containers for quick maintenance and easy application. Adventus products and technology optimize costs, speed up processes and solve problems definitively. The efficiency of Adventus products has been proved in the field in more than 2.500 remediation projects worldwide.
