  • Musing on Master Data Management, the New York City Water Supply… and Madonna?!

    MY DAD WAS A CIVIL ENGINEER for the New York City water department for 35 years, and when I was a kid it was fun to go to work with him when I was off from school because I got to see publicly inaccessible areas, buildings and underground spaces where the guts of the water supply system existed. I learned all about how massive amounts of water from many different sources were ...

  • Improvement on algae and turbidity removal in an integrated flotation and sedimentation unit using side flow-inclined plate settlers: evidence from a full-scale field experiment

    Operation of conventional drinking water treatment plants (DWTPs) is limited by seasonal variations in the characteristics of raw water, such as algae levels and turbidity. In this study, an integrated flotation and sedimentation unit (IFSU) with side flow-inclined plate settlers (SFIPS) was applied to enhance the removal ratio of algae and turbidity in a full-scale field experiment. To ...

  • Plastic as a Persistent Marine Pollutant

    Abstract Synthetic organic polymers—or plastics—did not enter widespread use until the 1950s. By 2015, global production had increased to 322 million metric tons (Mt) year−1, which approaches the total weight of the human population produced in plastic every year. Approximately half is used for packaging and other disposables, 40% of plastic waste is not accounted ...

  • Weir Maintenance Tips and Tricks

    devices are self-cleaning and require very little maintenance. However, in some applications, measuring flow with a weir is a much better choice. While weirs are also very accurate, they do require regular maintenance in order to function properly. If you’ve never had to perform weir maintenance before, you should learn about a few of the most common maintenance tasks and their ...

  • Scaling of nanofiltration membranes used for chromium(III) ions recovery from salt solutions

    The effect of membranes' structure on the efficiency of chromium(III) ions recovery from salt solution at low pH and the efficiency of chemical cleaning of these membranes were analyzed in this work. The nanofiltration membranes (DL and HL) used in this study were provided by GE Osmonics. The DL membrane had an irregular, dense support layer structure, while the HL membrane had a loose one. In ...

  • Great Lakes restoration is under threat. Here’s why that matters

    Degraded by decades of pollution, the North American Great Lakes are finding new life through cleanup efforts now threatened by proposed federal budget cuts. The St. Louis River, which flows into Lake Superior — the greatest of North America’s Great Lakes — has a long and turbulent history. Once a portal for Native American trade and a garden for wild ...

  • Nitrogen removal in a shallow maturation pond with sludge accumulated during 10 years of operation in Brazil

    Accumulated sludge in polishing (maturation) ponds reduces the hydraulic retention time (smaller useful volume), and this could potentially lead to a decrease in performance. However, settled biomass, present in the sediments, can contribute to nitrogen removal by different mechanisms such as nitrification and denitrification. This study investigated the influence of the bottom sludge present ...

  • Combination of novel coalescing oil water separator and electrocoagulation technique for treatment of petroleum compound contaminated groundwater

    In the present study a combination of a novel coalescing oil water separator (COWS) and electrocoagulation (EC) technique was used for treatment of petroleum product contaminated groundwater. In the first phase, COWS was used as the primary treatment. Two different types of coalescing media and two levels of flow rates were examined in order to find the optimum conditions. The effluent of COWS ...

  • Impact of surface maintenance on BioSand filter performance and flow

    The BioSand filter (BSF) is a household scaled, intermittently operated, slow sand filter. The BSF requires maintenance to remove trapped sediments. This study evaluated the effects of maintenance on the filter's flow rate and performance. Four concrete BSFs received three styles of maintenance: surface agitation (SA), stirring method (SM), and sand removal (SR). Effluent water was collected ...
