Provect-CH4® Methane Inhibitor
Provect-CH4® is a food-grade, natural source of Monacolin K (otherwise known as Lovastatin) that is used to prevent methane (CH4) production by inhibiting the growth and proliferation of methanogenic Archaea. In environmental remediation applications, it is a formulation component to Provectus technologies Provect-IR and Provect-IRM for reductive dehalogenation (ERD) and in situ chemical reduction (ISCR) amendments rendering them safer and more effective. Provect-CH4 is the only ERD/ ISCR technology component that will rapidly improve remedial performance while simultaneously reducing or significantly minimizing the production of methane. The benefits are notable:
- More Efficient = More Cost Effective: Production of methane is a direct indication that the hydrogen generated from the organic carbon amendments was used by methanogens and the amendment has been wasted because it was not utilized by acetogens or dehalorespiration. By inhibiting the growth and proliferation of methane producing Archaea, chlororespiring bacteria can become the more dominant bacterial populations.
- Safer: Methane is explosive with an LEL of 5% and an UEL of 15%. Production of methane will result from the addition of any conventional ERD or ISCR amendment: excessive and extended production of methane can result in elevated in groundwater concentrations (as high as 1,000 ppm have been reported) which can lead to accumulation in soil gas subsequently impacting indoor air. State specific regulations for methane in groundwater have been promulgated, with others pending for soil gas and indoor air.
- Ease of Use: Green and sustainable. All components integrated in a single package. Logistics with no surprisess.
- Patented Technologies: Technology end users and their clients are fully protected from all Patent and other legal issues.
With widely varying degrees of success, other approaches such as managing pH and using slower-release, cellulose based carbon sources (lignolytic bacteria are not commonly thought to produce methane) have attempted to manage methane production during remedial applications. However, Provect-CH4 is the only reagent designed to actually inhibit the production of methane in a safe, reliable and predictable manner (US Patent No. 9,221,669 B2).
Provect-CH4® Advanced Methane Inhibitor
Provect-CH4® Advanced represents our latest development in the science of applied antimethanogenic reagents (AMRs) for controlling excessive methanogenesis during in situ remedial action. Provect-CH4® Advanced is a proprietary mixture of plant extract oils/saponins in combination with red yeast rice extract that prevents methane (CH4) production by controlling the growth and proliferation of methanogenic Archaea. This advanced AMR formulation offers the benefits of:
- Expanded Mode of Action = More Effective
- Extended Release = Increased Longevity
- Ease of Use = Oil-Based Reagents More Compatible with Certain ERD/ISCR Amendments Supplied by Provectus Environmental Products: EZVI, ERD-CH4, ERD-Ole, and SRA.
With widely varying degrees of success, other approaches such as managing pH and using slower-release, cellulose based carbon sources (lignolytic bacteria are not commonly thought to produce methane) have attempted to manage methane production during remedial applications. However, Provect-CH4® and Provect-CH4® Advanced are the only reagents designed to actively control the production of methane in a safe, reliable and predictable manner (Mueller and Booth, 2016; US Patent Office Scalzi et al, 2013, 2014; US Patent No. 9,221,669 B2). In addition to the safety issues, associated with elevated methane in groundwater, soil gas, and indoor air, this effect also promotes more efficient use of the hydrogen donor.
