  1. Three Post-Peak Projects To Improve DC Operations
    8/1/2017

    Now that the peak season dust has completely settled, it’s the perfect time for a tune-up in your warehouses and DCs. Here, are some DC improvement ideas.

  2. Ozonia M and FiltraFast Provide New Options For Treatment Facilities
    11/20/2017

    If you don’t need the performance of an ultrafiltration membrane but also want to avoid the large footprint of a conventional media filter, you might want to consider FiltraFast extreme rate compressible media filters. As Ryan Hess, Director of Advanced Separation with SUEZ Water Technologies suggests in this Water Talk interview, “They provide roughly ten times the hydraulic loading rate of conventional media filters.”

  3. EPA Integrates Emergency Response To Help Make Informed Mission-Critical Decisions
    5/14/2018
    The EPA and Tetra Tech have iteratively developed a robust emergency response solution over time, by learning from individual site-specific cleanup activities that occur every day and scaling these activities during significant response events.
  4. Water And Food: One Man’s Vision
    10/2/2017

    Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.

  5. Greenhouse Gas Flow Monitoring
    12/27/2017

    Last year the EPA implemented new regulations entitled “Mandatory Reporting of Greenhouse Gases.” The new regulations called for certain facilities emitting 25,000 metric tons or more per year of specified GHG’s to provide an annual report of their actual GHG emissions. 

  6. The Duperon® Flexrake®: Inventing A Product That Defined A Segment
    2/23/2018

    In 1993, the Duperon® FlexRake® entered the market as the first multi-rake wastewater screen to operate without a lower sprocket, bearing or track. Designed by Duperon Corporation founder Terry Duperon, the patented equipment reflected his belief that mechanics should operate as simply as possible. The result was a mechanically-cleaned bar screen that consisted of just three main components — screen, raking device and drivehead. Despite its simplicity, the unit quickly proved to be far more reliable than other, more complicated designs. Paired with the industry’s first five-year warranty in wastewater, the Duperon® FlexRake® soon became a benchmark for low maintenance and ease of operation. 

  7. Water Agency Welcomes The Future With Ignition
    12/23/2017

    While many water/waste water facilities stick with outdated supervisory control and data acquisition (SCADA) systems, Aguas de Saltillo in Mexico is taking a different path and accelerating toward Industry 4.0 — and is seeing numerous benefits today.

  8. From Drought To Flooding: California Struggles With Turnaround
    2/15/2017

    In a drastic about-face, California has gone from historically desperate drought conditions to an inundation of water that has brought its own set of problems.

  9. A More Efficient Approach To EPA Stage 2 DBP Compliance
    4/20/2018

    Everyone wants pathogen-free drinking water, and adding chlorine is a great way to get it. Unfortunately, the dirtier a water treatment plant (WTP)’s raw water inflow — in terms of natural organic matter (NOM) or microbial organisms — the more disinfection byproducts (DBPs) the chlorination process will generate in the form of trihalomethanes (THMs) and haloacetic acids (HAAs). Those DBPs increase the risk of non-compliance with the U.S. EPA’s Disinfectants and Disinfection Byproducts Rules. Choosing the right instrumentation to measure NOM through spectral absorption coefficients (SACs) can have a big impact on treatment strategies — in terms of both costs and compliance performance.

  10. Biosimilar Producer Relies On Flexible Development Platform
    2/15/2017

    For AlphaMab, adopting the latest production technologies were driven by two other interrelated reasons: manufacturing flexibility and time to market.
