  • BM Respirometry Study Toxicity & Biodegradability of a Refinery polymer stream, when treated in the activated sludge process of the plant - Case Study

    This “batch system” respirometer consists of: a single thermostatically controlled vessel, divided into two interconnected compartments with closed recirculation loop between the two. A constant air flow is supplied via a ceramic diffuser in the conditioning compartment, and a combined oxygen/temperature sensor in the reaction compartment controls the DO and temperature. Both ...

  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...
