  • Biodegradability of Dissolved Organic Nitrogen: Adaptation of the BOD Test

    To prevent eutrophication in receiving waters, many astewater treatment plants are being firected by regulatory agencies to achieve very low levels of total nitrogen (3-4 mg/L TN or lower) in the effluent. Dissolved organic nitrogen (DON) component is included within these total nitrogen limits. The regulations assume that DON is completely biodegradable, and therefore needs to be included in any ...

  • Microorganism inactivation by an ozonation step optimized for micropollutant removal from tertiary effluent

    This paper demonstrates the additional benefit of the microbicidal efficacy of an ozonation plant implemented for micropollutant removal from tertiary effluent. Due to the low amount of viruses and protozoa in the tertiary effluent, bacteriophage MS2 and spores of Bacillus subtilis were dosed as surrogates. At specific ozone consumptions of 0.6 and 0.9 g O3/g dissolved organic ...

  • PeCOD® Case Study #13 Airport De-Icing

    De-icing of aircrafts and airfield pavement is important to ensure the safety of passengers and cargo operators. These operations can have negative environmental impacts, due to the presence of ethylene glycol and propylene glycol, which contribute to high levels of BOD in surface water.  Regulations are in place to ensure that waste from de-icing operations are properly collected and ...

  • Evaluation of sludge properties in a pilot-scale UASB reactor for sewage treatment in a temperate region

    In this study, continuous operation of a pilot-scale upflow anaerobic sludge blanket (UASB) reactor for sewage treatment was conducted for 630 days to investigate the physical and microbial characteristics of the retained sludge. The UASB reactor with a working volume of 20.2 m3 was operated at ambient temperature (16–29 °C) and seeded with digested sludge. After 180 days of operation, when the ...

  • Greywater characterization and handling practices among urban households in Ghana: the case of three communities in Kumasi Metropolis

    Greywater management in Ghana receives little or no attention although untreated greywater is associated with environmental and public health risks. This paper assesses greywater characteristics and handling practices among urban households in three selected communities in Kumasi, the second largest city of Ghana. The study involved in-depth surveys (interviews and observations) with 90 ...

  • Effect of glucose on enzyme activity and color removal by Trametes versicolor for high strength landfill leachate

    This research was carried out to study the treatment of landfill leachate by immobilized Trametes versicolor BCC 8725. Leachate was collected from Nonthaburi disposal site of Thailand from a pipe as discharged from landfill to the stabilization pond. Batch experiments were conducted to determine the effects of carbon source (glucose) on the biomass growth of fungi and the treatment of leachate in ...

  • Treatment performance and microbial characteristics in two-stage membrane bioreactor applied to partially stabilized leachate

    A two-stage membrane bioreactor system was applied to the treatment of partially stabilized leachate from solid waste landfill in Thailand. In the system, an anoxic tank with incline tube for biomass separation from re-circulated sludge is followed by a second-stage aerobic tank in which a direct submerged hollow-fiber membrane module is used for solid–liquid separation. During steady operation ...

  • The increasing importance of assessing toxicity in determining sludge health and management policy

    The harm caused by toxic industrial effluents to sewage treatment works, has been recognised for many years. These can cause reduction in biodegradable efficiency, with an associated requirement for longer treatment time, and in extreme cases, toxic shock can kill off the secondary tanks. Currently, the presence of harmful industrial effluents is made evident by their effects ...

  • Post Lagoon Nitrification in Cold Climates

    A Submerged Attached Growth Reactor (SAGR) Demonstration Site has been in operation following a primary aerated lagoon in Steinbach, MB since August 2007. This system provides nitrification, with influent winter water temperatures (post lagoon) below 0.5 degrees Celsius. The performance objective of the system was to achieve effluent cBOD5 and TSS levels of less than 10 mg/L, and ammonia of less ...
