  • Treating organic waste with Cambi THP

    ABSTRACT This paper describes how the Cambi Thermal Hydrolysis Process (THP) treats biodegradable organic waste and converts it to renewable energy and pathogen-free and bio-fertilizer. The interest for the process is expected to increase due to new environmental legislation as well as increasing demand for renewable energy. The implementation of the European Landfill Directive 1999/31EC and the ...

  • THyPAD – From Pilot to Full Scale Application at Hamar WWTP

    During 2001-2003 the city and county of San Francisco completed a two-year pilot study of pretreatment processes to mesophilic anaerobic digestion for improved biosolids stabilization and production of biosolids suitable for unrestricted reuse (class A biosolids). The pre-treatment options investigated included:   1. A thermophilic (55 °C; TP) process with 5 days hydraulic retention time (HRT).   ...

  • Anaerobic model for high-solids or high-temperature digestion – additional pathway of acetate oxidation

    Current anaerobic digestion models cannot properly simulate processes that are operated under high solids concentrations or high temperatures. A modification to existing models has been implemented by adding important missing degradation pathways, to accommodate these systems without artificially recalibrating the model parameters. Specifically, we implemented the alternate acetate oxidizing ...

  • Trends in biosolids handling technologies: economics and environmental factors

    Changes in activated sludge technology, with a much greater focus on nutrient removal instead of removal of organics, together with relatively long sludge mean that the primary sludge stream has been lost, and the sludge produced is less degradable. At the same time with the growing importance of sustainable solutions, beneficial agricultural use is being increasingly used. This changes quality ...

  • Food waste – global warming potentials of the options

    Food waste (FW) is a problem and an opportunity. This paper will review the alternativen routes for its management. In the UK, the majority of FW is still landfilled. Traditionally, FW has been fed to pigs but part of the reaction to the 2001 outbreak of foot and mouth disease in the UK was to ban this “swill feeding” and introduce stringent requirements for treating FW that later was the basis ...

  • Energy Recovery from Residual Waste by Means of Anaerobic Digestion Technologies

    ABSTRACT Anaerobic digestion (AD) is a natural process, spontaneously taking place in natural surroundings, such as marshes,bogs, paddies, or in cesspits, landfills, and dedicated digesters, used for the conversion of organic waste into a rich gas. Typical AD substrates are: manure, sewage sludge, high BOD wastewater, and – more recently - the organic fraction of Municipal Solid Waste (MSW), ...

  • Pilot-Scale Biofilter Test for Treating Zimpro Odors

    The thermal sludge conditioning process of U.S. Filter/Zimpro Corporation, Rothschild, Wisconsin (Zimpro process) is primarily used to improve dewatering characteristics of the waste sludge. The process entails a partial breakdown through oxidation and hydrolysis of complex, high molecular weight organic compounds, such as, proteins, fibers, carbohydrates, and fats. The partial breakdown of ...
