  • Analysis of reconstruction of the composition of liquid radioactive waste released into the Techa River in 19491956

    An analysis of archival data of liquid radioactive waste samples and Techa River bottom sediments was made, taking into consideration the radiochemical methods for extraction and beta-emitting radionuclide activity measurements existing in the early 1950s. It was stated that the radionuclide composition of the routine and accidental liquid radioactive waste releases in 19491951 corresponded to ...

  • Decontamination of a natural multicomponent aqueous liquid waste by titania photocatalysis

    The aerobic photocatalytic degradation of municipal dump-site leachate at 300 K has been carried out in a pilot-scale bubble column reactor. The leachate feed is a complex mixture of various organics and nitrogenous compounds. Runs were performed over a 48-hour period at atmospheric pressure. Compositional analysis of aliquots from the reactor revealed simultaneous total organic carbon removal ...

  • Environmental analysis of management systems for organic waste

    Organic waste is generally easily degradable and has a high nutrient content. Thus the risk is large that the handling of such material will generate emissions that affect the environment. New systems have been introduced for managing organic waste fractions from households and industries. These systems are based on source separation and biological treatment, e.g. composting and anaerobic ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Measurements of nanomaterials in environmentally‐relevant water matrices using liquid nebulization / differential mobility (LN/DMA) analysis

    A liquid nebulization‐differential mobility analysis (LN/DMA) methodology was evaluated for the measurement of the size distribution and quantitative mass concentration of nanomaterials in environmentally relevant aqueous media. The analysis time is 8 min, the method requires little routine sample preparation and less than 8 mL of sample. The method can be used for rapid, direct analysis of ...

  • Production of propionic acid-enriched volatile fatty acids from co-fermentation liquid of sewage sludge and food waste using Propionibacterium acidipropionici

    Volatile fatty acids (VFA), derived from sludge fermentation, have been used as one effective carbon source for biological nutrient removal, especially favorable with VFA containing with high levels of propionic acid. In this paper, a new fermentation method was employed to significantly produce the propionic acid-enriched VFA from the co-fermentation liquid of sewage sludge and food waste: ...
