  • WWTP Air Handling Control Philosophies: Do’s And Don’ts

    Without an appropriate control strategy, even the best wastewater treatment plant (WWTP) equipment can struggle to deliver maximum efficiency. Because energy costs represent up to 60 percent of WWTP plant operating expense, air distribution designs and changing loading (biochemical/biological oxygen demand [BOD]/chemical oxygen demand [COD], ammonia) demands require control strategies designed to adapt to all eventualities efficiently. The following checklists, plus important Do’s and Don’ts, can help in identifying an underperforming control strategy and developing a better one.

  • 15 Steps To Identifying Your Best WTP & WWTP Flow Metering Options

    There’s a lot to be said for the old adage, “Use the right tool for the job.” When it comes to flow meters for municipal or industrial water treatment plant (WTP) and wastewater treatment plant (WWTP) operations, however, the sheer number of choices can be overwhelming. That is where using a process of elimination to winnow out styles that don’t fit the performance criteria of an application can make it easier to compare the few remaining options. Here is a checklist of considerations to accelerate that process.

  • The Data Influx: Transforming Data Overload Into Business Insights
    The Data Influx: Transforming Data Overload Into Business Insights

    “We have too much data” is the refrain we continually hear from water utilities. It’s no surprise that managing data from multiple sources and turning it into business insights presents a daunting challenge; however, data influx does not have to be a burden. When managed well, there’s no such thing as too much data, especially if your business is implementing a big data strategy — a topic that has implications and reach beyond the scope of this paper.

  • Effective Utility Management Starts With Data
    Effective Utility Management Starts With Data

    Over the past decade, there has been a considerable effort in the water sector to address industry shortcomings through collaboration. And perhaps there’s been no greater initiative to try to help water utility managers in their day-to-day and future planning than the Effective Utility Management (EUM) Initiative.

    Big Data is more than a marketing buzzword. It’s become an essential tool for helping utility operators prioritize capital investments, manage network assets, and provide a higher level of service to customers.

  • Using Flow Meters To Reduce Non-Revenue Water

    Utility managers are continually challenged to run water systems in the most efficient manner. Reducing non-revenue water (NRW) is an important component for system efficiency. In many states, regulators are placing caps on NRW or requiring reductions in the amount of NRW. Accurate and well-planned flow measurement can be used to locate areas of water leakage and reduce NRW.

    In the Semiconductor industry, raw water is treated in two steps; the first treatment is used to produce “make-up water” and the second phase involves turning make-up water into ultrapure water. This ultrapure water is then used for the final rinsing of fabricated wafers.

  • Peaking Factors And Hydraulics In Wastewater Screen Sizing

    Dealing with fine particulate matter, nutrients, and pathogens is essential for wastewater treatment plants (WWTPs) striving to meet Clean Water Act (CWA) effluent standards. Before that stage, however, come important considerations about removing larger debris that can clog pumps, overload clarifiers, or disrupt other downstream processes — especially during periods of elevated flow and debris loading.

    Fine Tune Your Lab Testing Accuracy With Compliant Proficiency Testing (PT)

    Proficiency Testing (PT) is the name used by the International Standards Organization for a procedure also known as “inter-laboratory study” or “external quality assessment” or “ring test”. Proficiency testing, in simple terms, comprises a sample sent to a group of laboratories for measurement. The labs know what might be in the sample, but they don’t know exactly what is there or the concentration. Their results are compared with the known or true value and the lab is assigned a “Z” score to show how closely their result came to the target.

    Smartphone App Delivers Reproducible And Precise pH Analysis

    Traditionally when it comes to analysis, there have been two ways to measure pH. The first is the inexpensive method of using test strips, which requires little time or training. The second requires the use of a pH electrode or probe and because it requires more training, time, and equipment, is far more expensive. However, a hybrid application is now available that brings together the ease of use of test strips with technology to ensure preciseness.

    Zero Liquid Discharge — Maximum Recovery And Why It Finally Makes Sense

    Our planet continues to become increasingly more crowded.  Pollution and waste are showing irreversible impact on a global scale, and it has become necessary to come up with solutions in all industries.  It is widely known, though perhaps not publicly thought of, that the process of purifying water creates waste.  As we remove the minerals and impurities from water, we inherently condense those impurities into a smaller body of water.  This waste affects the environment in various adverse ways.  The solution lies in a concept known as Zero Liquid Discharge (ZLD).
