  • Assessment of treatment capabilities of Varthur Lake, Bangalore, India

    Manmade waterbodies have traditionally been used for domestic and irrigation purposes. Unplanned urbanisation and ad-hoc approaches have led to these waterbodies receiving untreated sewage. This enriches and eutrophies the waterbody. A physico-chemical and biological analysis of sewage-fed Varthur Lake in Bangalore was carried out and its treatment capabilities in terms of BOD removal, nutrient ...

  • Flavour Industry Wastewater Management Case Study

    This study is carried out to propose an appropriate treatment technology for wastewater discharged from a flavor production factory. Industrial wastewater discharged from this factory ranges between 50–70 m3/d with an average value of 60 m3/d. The major source of pollution in this factory is due to cleaning of the vessels therefore the treatment has been carried out on the end-of pipe wastewater. ...

  • Mixing To Enhance Facultative Wastewater Lagoon Treatment

    SolarBee® & GridBee® Are Leading The Way In most lagoons, sunlight causes a hard stratification at 12 to 18 inches of depth.  The top water is warmer and thick algae populations are producing supersaturated dissolved oxygen (DO).  The DO gasses off at the surface and is not readily available deeper in the pond for use by BOD-reducing bacteria. Meanwhile new ...

  • Performance evaluation of 388 full-scale waste stabilization pond systems with seven different configurations

    Waste stabilization ponds (WSPs) and their variants are one the most widely used wastewater treatment systems in the world. However, the scarcity of systematic performance data from full-scale plants has led to challenges associated with their design. The objective of this research was to assess the performance of 388 full-scale WSP systems located in Brazil, Ecuador, Bolivia and the United ...
