  • Features of Sanitary Butterfly Valves

    The disc and the sanitary butterfly valve body can be in spheroidal cast iron or in steel. At this valve, when it is in the open position, small localized losses of pressure occur, while strong turbulence and vibrations are created in case of partial closure. Therefore, it is not very suitable for regulation. The maneuvers of the small diameter butterfly valves can be done ...

  • What too much water can do to your collection systems

    In areas with a high water table, or for cities more prone to flooding, your underground infrastructure can become inundated with groundwater and stormwater. And despite stormwater systems being built for this type of collection, there are a number of things that can go wrong for both types of collection systems underground—and above ground—that can lead to contamination or degraded ...

  • Urban waste- and stormwater management in Greece: past, present and future

    Urban wastewater and storm management has a long history which coincides with the appearance of the first organized human settlements (ca. 3500 BC). It began in prehistoric Crete during the Early Bronze Age (ca. 3200 BC) when many remarkable developments occurred in several stages known as Minoan civilization. One of its salient characteristics was the architecture and ...

  • Application of batch tests to assess antibiotic loads in anaerobic processes

    The presence of antibiotics in drinking water and wastewater has not been widely studied because the sanitary engineering sector mainly focuses on the removal of organic matter and nutrients. There is a lack of environmental regulations for pollutants like antibiotics. Batch tests analyse biodegradability to measure the anaerobic degradation potential of the substrate, or they can be used as ...

  • Nutrient recovery from airplane wastewater: composition, treatment and ecotoxicological assay

    For the 2014 World Cup and the 2016 Olympic Games, Brazil has expanded its airport infrastructure. This will lead to an increase in wastewater generation from aircrafts. This wastewater is traditionally taken from the aircrafts and disposed in the public sewage collection system. However, this residual water may have a different composition than the usual sanitary sewage. Therefore, it is ...
