  • Microbiology: The Key to Wastewater treatment case study

    The biological treatment of wastewater relies mainly on a consortium of heterotrophic and autotrophic bacteria. The fecal bacteria that are constantly introduced into the collection system are not the optimal bacteria for degrading the contaminants present in wastewaters. The soil bacteria that are introduced through inflow and infiltration are more effective at degrading the wastes and can ...

  • Water management in cities of the future using emission control strategies for priority hazardous substances

    Cities of the future face challenges with respect to the quantity and quality of water resources, and multiple managerial options need to be considered in order to safeguard urban surface water quality. In a recently completed project on ‘Source control options for reducing emissions of Priority Pollutants’ (ScorePP), seven emission control strategies (ECSs) were developed and tested within a ...

  • Rainwater harvesting: An untapped resource

    The collection of rainwater as a source of relatively clean water has been a common practice of humankind since the dawn of civilization. Before the development of any treatment processes, it was the primary source of potable water for those people without access to other sources of water (rivers, lakes, etc.) As cities developed, infrastructure became more centralized. Municipalities took over ...

  • Understanding the True Cost of Water

    Overcoming Barriers to Corporate Water Stewardship For companies pursuing corporate water stewardship strategies, a common barrier to action is the perceived low cost of water “at the tap.” Water reduction, reuse, and recycling projects often do not meet investment hurdle rates or compare positively to other investments. This also acts to limit community and watershed ...

  • Understanding the True Cost of Water - Overcoming Barriers to Corporate Water Stewardship

    For companies pursuing corporate water stewardship strategies, a common barrier to action is the perceived low cost of water “at the tap.” Water reduction, reuse, and recycling projects often do not meet investment hurdle rates or compare positively to other investments. This also acts to limit community and watershed engagement actions outside of the fence line as well. Our water and ...

  • Sewage Pump - Klargester is the market leader for small and medium-sized domestic treatment plant and waste water treatment systems in the UK

    There are a variety of solutions on the market for properties in the UK that are unable to connect to the main sewer by gravity. However, UK building regulations dictate that pumping stations must be used whenever possible. As a result, pumping stations are the most commonly specified solutions for off-mains developments, ahead of sewage treatment plants, such as the Biodisc, and septic tanks. ...
