  • Accuracy of different sensors for the estimation of pollutant concentrations (total suspended solids, total and dissolved chemical oxygen demand) in wastewater and stormwater

    Many field investigations have used continuous sensors (turbidimeters and/or ultraviolet (UV)-visible spectrophotometers) to estimate with a short time step pollutant concentrations in sewer systems. Few, if any, publications compare the performance of various sensors for the same set of samples. Different surrogate sensors (turbidity sensors, UV-visible spectrophotometer, pH meter, conductivity ...

  • Water at the Beach - Hotel resort reuses its greywater with new treatment solutions - Case Study

    Greywater typically consists of shower water, sink water, dishwater and laundry water, which comprises 50% to 80% of domestic wastewater consumption in a hotel or resort property. Resort property owners and operators typically understand water conservation, as they feel the cost of excess water usage and water mismanagement on their financial bottom line. The use of recycled water can have a ...

  • Softener Plant Supplier in Chennai, Chennai

    Water is and will be the primal focus as the world evolves every day. We might be surrounded by large water masses, but those still need to be effectively utilized. Water, today is available in different formats or to be more modern, in different Avatars. The key question is how much can be made effective for human consumption. The resolution lies in treatment of water fit enough for consumption ...

  • The mystery of electronic water treatment unveiled

    The problems of scale are well known to those living and working in "hard" water areas. Scale is the undesirable consequence of water supplies becoming super-saturated with dissolved minerals.  These problems are of greater significance if found in industrial water systems and commercial buildings. Scaling problems commonly occur, even in "soft" water areas, when a fluid stream is ...

  • RO monitors and Controllers: pros and cons

    A look at a range of devices for watching TDS. One major question a potential customer may ask before they purchase a point-of-use/point-of-entry (POU/POE) water treatment system is, “How often will I need to change the filter?” Maintenance and service are directly related to two of their major concerns: money and health. People don’t want to spend money unnecessarily, yet they ...

  • Hart`s E&P: Optimizing production, economics in mature fields

    To generate cash flow in low-price markets, operators have historically turned to the resource they can count on most—fields that have proved they can produce. But optimizing production from mature fields presents its own set of challenges that have the potential to offset the benefits of improved production with higher capital expense. Increasing production while lowering lifting costs and ...

  • 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 ...
