Micro Carbon Technology~®: A Powerful and Proven Technology to Improve Wastewater Treatment Efficiency

摘要

Bioremediation is an efficient method for treating pulp and paper wastewaters. Essential to successful bioremediation is that microorganisms have the specific bioavailable nutrients they need. Phosphorus, a key macronutrient for microorganisms, is typically not sufficiently available in pulp and paper wastewater and must be supplemented. Because poorly performing wastewater treatment systems can become a significant factor in pulp and paper mill profitability, delivering bioavailable microorganism nutrition can have a significant impact on mill efficiency and profitability. Probiotic Solutions~® has developed a phosphorus product, Super Phos~® (SP), which is complexed with a proprietary carbon source as a nutrient carrier, Micro Carbon Technology~® (MCT). This technology provides very small carbon particles that have low molecular weight, greater specific surface area, and high cation exchange capacity. When complexed with micro-carbon, nutrients are adsorbed and become more chemically active and available to microorganisms. Four case studies are presented in which mills in the United States and China replace traditional phosphorus sources with SP (and micro-carbon). Results demonstrate that SP can replace much larger quantities of traditional phosphorus in bioremediation settings while maintaining or improving the health and diversity of beneficial microorganisms. This leads to system efficiencies, operational stability, and cost savings.
