  • Co-digestion of press liquids of source-sorted municipal organic waste in anaerobic sludge treatment of municipal wastewater treatment plants

    This paper describes a semi-continuous laboratory-scale investigation of a potential co-substrate for mesophilic anaerobic sludge digestion in a municipal wastewater treatment plant. A feed liquid produced from source-sorted municipal organic waste by pretreatment with a screw press was subjected to the investigation. Quantities produced in press trials as well as the composition of the feed ...

  • Demonstration of DeconGel at Oak Ridge National Laboratory building 2026

    Challenge In 2003 an area behind the hot cells in Building 2026 at the Oak Ridge National Laboratory (ORNL) was flooded with highly contaminated liquids when a liquid low level waste pipe became clogged. The main contaminants of concern are uranium and plutonium. Transferrable contamination levels are in the 1,000,000 disintegrations per minute range. The area is posted as an airborne ...

  • The effect of quench on Quantitating Alpha Radionuclides by Liquid Scintillation Counting

    Detecting and quantitating alpha emitting radionuclides are routine tasks in nuclear energy and environmental monitoring. For this purpose, liquid scintillation counting (LSC) is an excellent method because alphas are counted with nearly 100% counting efficiency with low backgrounds, even with severe quenching. Quenching agents such as inorganic acids, organic acids, and extractive scintillators ...

  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • Fluid Waste Management and Disposal Practices

    Prior to the early 80s and the introduction of AIDS into our society, infection control practices were designed almost exclusively to protect the patient from developing a nosocomial infection - an infection acquired after admission to the hospital. Protocols were focused on protecting the patient, with little or no ...

  • In-Situ thermal treatment of MGP waste and creosote

    Abstract: Remediation of coal tar at former Manufactured Gas Plant (MGP) sites, and creosote associated with wood preservative sites is challenging due to the viscous nature of the dense non-aqueous phase liquid (DNAPL) and the modest solubility and vapor pressure of the contaminants of concern (COCs). DNAPL seepage into surface water bodies, as well as groundwater plumes formed by the most ...

  • Digester Developers Target Mixed Organic Waste Streams

     emerging group of commercial companies see a viable business opportunity in North America around building, owning and operating larger scale anaerobic digestion (AD) facilities to process mixed organic waste streams. In some instances, the projects being proposed and constructed only include anaerobic digester operations. In others, there is a combination of digestion with back-end ...

  • Recycling Waste Products from Molasses Fermentation: CSR Distilleries

    CSR’s Sarina ethanol distillery has changed from an environmental pariah in the local community into a welcome industry. Through a world-first plant design, it has reduced steam and water consumption, improved plant productivity and product quality, and turned a pollutant into a saleable, import-replacing product. Instead of closing down in the face of community opposition to its environmental ...


  • CH#830 - Bioaugmentation Improves Performance of Brewery Waste Treatment Plant

    Introduction This packaging plant finishes 'heavy' beer, a liquid concentrate, into the well-known canned and bottled products. The plant handles 50,000 barrels per week and generates over 350,000 gallons of wastewater per day. Wastes are treated at the plant's 0.5 MGD waste treatment facility which operates under a standard discharge NPDES permit. Waste beer is the main constituent of ...

  • Simple design criteria and efficiency of hydrodynamic vortex separators

    Vortex separators still draw attention from specialists investigating the process of removing particles suspended in liquids. The devices are locally applied for waste water treatment in different systems – from storm waste water sewerage to water circulation in fish ponds. However, the methods for separator design presented in the literature are questionable. The paper presents two ...

  • Biosolids sampling and handling approaches for microbial analyses

     ABSTRACT The protection of human health and the environment while making the use of biosolids products more practical is a joint goal of utilities and regulatory agencies. Assuring the safety of biosolids is paramount to gaining wide public acceptance of this waste-to-beneficial use product. Making effective decisions about the safety of biosolids use relies on quality data. Satisfying ...

  • Recovery of Phosphorus from Sewage Sludge

    In the following, a method to recover phosphorus from sewage sludge as MAP (magnesiumammonium- phosphate, also called struvite) is to be presented. The process uses sulfuric acid to leach phosphorus out of digested sewage sludge. After solid-/liquid-separation, interfering metal ions in the liquid phase are inactivated through complexation. For the subsequent precipitation of the phosphorus, ...
