- Model QR (Quick Release) - Soluble Electron Donor for In Situ Bioremediation

0

Newman Zone QR is a blend of food grade electron donors, nutrients, cofactors and vitamins designed to stimulate rapid microbial growth. In microcosm studies, Newman Zone QR reduced PCE to ethene in half the time compared to sodium lactate. Common applications include anaerobic bioremediation of chlorinated solvents, nitrated explosives (RDX, HMX, TNT), selected toxic metals (Chrome VI), perchlorate, and nitrate.

A Complex Blend of Soluble Electron Donors

Newman Zone QR is a complex blend of food grade electron donors, nutrients, cofactors and vitamins. It is used as a rapidly utilized electron donor for enhancing the in situ bioremediation of chlorinated solvents, nitrated explosives (RDX, HMX, TNT), selected toxic metals (chrome VI), perchlorate and nitrate. Newman Zone QR provides microbes with a variety of soluble electron donors, vitamins, minerals and cofactors that stimulate microbial growth in ways that simple electron donors cannot.

Application

Newman Zone QR is diluted with water and injected below the water table to stimulate in situ bioremediation. Active within days the carbohydrates and lactate donors promote rapid biodegradation. The complex sugars, phospholipids and soluble protein can extend fermentation longer than simple substrates like lactate or sugars. For projects that need to stimulate biodegradation for years, rather than months, Newman Zone QR should be combined with a slow release donor such as Newman Zone ® or Newman Zone HRO.

Benefits – No Added Sodium

Unlike 60% sodium lactate, Newman Zone QR contains no sodium salts. The lactate content is provided by potas - sium salts providing potassium as a microbial nutrient as well as avoiding regulatory concerns over sodium content.

Benefits – Easily Used in the Field

Newman Zone QR diluted with water has a low viscosity similar to water. The Newman Zone QR blend provides everything needed for optimal microbial growth in one easy to use, cost-effective package, and eliminates the need to blend donors, vitamins, yeast extract or other additives in the field.

Benefits – Better Performance Than Simple Electron Donors

Newman Zone QR is designed to stimulate rapid microbial growth. The formulation is optimized for anaerobic dechlorinating bacteria such as Dehalococcoides through a blend of electron donor, nutrients, cofactors and vitamins. In laboratory microcosms with the KB-1 culture and 10 mg/L of PCE, a simple 60% sodium lactate donor had converted only a small portion of PCE to ethene during the first 28 days of incubation. In contrast the Newman Zone QR amended microcosm exceeded the performance of the 60% sodium lactate in half the time. After 28 days Newman Zone QR had produced complete conversion of 10 mg/L of PCE to ethene.
