Wastewater Features

  1. Is Stormwater The Industry’s Red-Headed Stepchild?
    8/14/2018

    The National Municipal Stormwater Alliance recently released the 2018 State of Stormwater Report on municipal separate storm sewer system (MS4) permits under the NPDES permitting program — the first-ever in a series that will publish annually. The Alliance also explained the somewhat distressing reason why the report is necessary: Stormwater is being largely ignored.

  2. Septic Systems: The Good, The Bad, And Hyperbole

    Sorting through practical, legal, and environmental considerations related to Michigan House Bills 5752 and 5753 — proposed oversight for onsite wastewater treatment systems

  3. Evaluating The Effectiveness Of Vacant Lots As Green Infrastructure In Buffalo, NY
    8/3/2018

    Rainfall replenishes water supplies and keeps our urban landscapes looking green, but even small storms can cause localized flooding and inundate sewer systems. It’s a problem that the City of Buffalo, New York, knows all too well. Buffalo has a combined sewer system that is designed to collect both wastewater and stormwater in a single pipe and send this combined flow to a treatment plant. As in many cities, stormwater reduces the capacity of the sewer system, and this often causes what’s called a combined sewer overflow (CSO).

  4. EPA’s ENTACT Study Breaks New Ground With Non-Targeted Research
    8/1/2018

    EPA scientists are leading a multi-phase project to evaluate the ability of non-targeted analysis laboratory methods to consistently and correctly identify unknown chemicals in samples. EPA’s Non-Targeted Analysis Collaborative Trial (ENTACT) was formed in late 2015 and includes nearly 30 academic, government, and industry groups. Non-targeted analysis involves analyzing water, soil and other types of samples to identify unknown chemicals that may be present, without having a preconceived idea of what chemicals may be in the samples.

  5. Ceramic Membranes Offer High Performance, Long Life, And Lower Operating Costs For Water Treatment
    7/23/2018

    Microfiltration and ultrafiltration have become mainstays in the water treatment arena. These processes remove contaminants from water by passing it through a low-pressure membrane. Membrane filters are constructed with a variety of materials with various pore sizes. The challenge is determining which best suits the application with regard to performance, cost, and ease of operation.

  6. California — A State Ready And Willing To Embrace Recycled Water
    7/13/2018

    Water has never been more in demand, and innovative approaches to improving water security have never been more imperative. As our global population grows exponentially, cities and towns expand to accommodate new inhabitants, providing the resources and services they need. Rapid agricultural and industrial development continues apace.

  7. Pride And Prejudice: A Philadelphia (Water Department) Story
    7/12/2018

    Recently, I had the opportunity to tour a unique and innovative facility, the Bureau of Lab Services (BLS), the “water quality heartbeat of the Philadelphia Water Department” (PWD), as described by BLS director Gary Burlingame.

  8. Benefits Of Remote Access To Primary Wastewater Treatment
    7/12/2018

    A real-world, industrial application of remote process monitoring proves that a little technology can go a long way in terms of cost savings and process improvement.

  9. Innovative Water Use In An Urban Setting
    7/12/2018

    Rather than waiting on water scarcity and reacting to a crisis, the San Francisco Public Utilities Commission is forging its own future, and that of others, by blazing a trail of water-reuse practice and policy.

  10. Integration Of CFD Modeling In Wastewater Treatment Design
    7/12/2018

    This overview of computational fluid dynamic (CFD) modeling for wastewater treatment plant design reveals how it is applied to different system components, as well as why (i.e., the benefits) and when (in the design process) it should be applied.
