  • Potential health implications of water resources depletion and sewage discharges in the Republic of Macedonia

    Potential health implications of deficient sanitation infrastructure and reduced surface water flows due to climate change are examined in the case study of the Republic of Macedonia. Changes in surface water flows and wastewater discharges over the period 1955–2013 were analyzed to assess potential future surface water contamination trends. Simple model predictions indicated a decline in ...

  • Urine nitrification and sewer discharge to realize in-sewer denitrification to simplify sewage treatment in Hong Kong

    The chemically enhanced primary treatment works in Hong Kong will be upgraded for biological nitrogen removal. This study proposed a novel approach to waive the upgrading by urine source-separation, onsite nitrification and discharge of nitrified urine into sewers to achieve in-sewer denitrification. Human urine was collected and a lab-scale experiment for full urine nitrification was conducted. ...

  • An alternative to biological treatment for sewage

    Most sea-side towns discharge sewage into the sea, normally some distance off-shore, via an extended out-fall sewer. A town of 100,000 population will produce more than 14,000 cubic metres (3,000,000 gallons) of sewage every day of the year. No small problem. In some coastal locations the sewage used to receive only basic, simple treatment, usually  "screening" to remove any large ...

  • Cruise ship discharge assessment report

    Cruise ships operate in every ocean worldwide, often in pristine coastal waters and sensitive marine ecosystems. Cruise ship operators provide amenities to their passengers that are similar to those of luxury resort hotels, including pools, hair salons, restaurants, and dry cleaners.

  • Occurrence of glucocorticoids discharged from a sewage treatment plant in Japan and the effects of clobetasol propionate exposure on the immune responses of common carp (Cyprinus carpio) to bacterial infection

    Here we evaluated the environmental risks to common carp (Cyprinus carpio) posed by glucocorticoids present in sewage treatment plant (STP) effluent. To gather information on the seasonal variations in glucocorticoid concentration, we sampled the effluent of a Japanese STP every other week for 12 months. Six out of nine selected glucocorticoids were detected in the effluent, with clobetasol ...

  • Climate change a threat to sewage systems

    Many cities could face problems with their sewage in the future. A research study for Stockholm shows that a change in precipitation, combined with a population increase, could bring disruptions as early as the middle of the century. Climate change could put more pressure on the sewage systems in the future. Climate scenarios indicate critical factors such as increased volumes of rain and rising ...

  • Sewage Treatment – Small System in a Watershed

    ABSTRACT:Water purveyors, in examining their watersheds, have raised concerns over small community pollution sources, particularly over phosphorus, nitrogen, pathogens and suspended solids. As our population has increasingly moved further upstream in watersheds, the application of classic sewage treatment plants (STPs) have been pushed to their limit of design, especially in light of the need by ...
