  1. Ephrata Borough Authority Battles Chronic Sludge Settling 7/29/2019

    Ephrata Borough Authority WRRF, located in the MidAtlantic region of the United States, has been battling chronic sludge settling issues since undergoing a BNR upgrade in 2011 to meet new permit limits. During the winter months, SVI values have reached as high as 300 mL/g.

  2. Production Of Recombinant Proteins Using A Scalable Metal Affinity Resin 11/7/2017

    Immobilized metal affinity chromatography (IMAC) is one of the most popular tools for the preparation of recombinant proteins in a single step.

  3. A Closer Look At Cost-Effective Filtration Technology 2/5/2021

    From the growth of contaminants of emerging concern — such as PFAS and 1,4-dioxane — to dwindling water supplies and tighter budgets for capital projects, the ability for municipalities and industry to generate clean, safe water has been a growing challenge across the country. 

  4. AOP Removal In Aquifer Remediation 4/15/2024

    In this case study, read about a successful pilot test in Long Island, New York, removing 1,4 dioxane from water. The technology used offers improved efficiency, reduced maintenance, and ongoing monitoring for reliable water treatment.

  5. PFAS Removal System Proven Effective In Removing Both Long And Short Chain PFAS 9/16/2025

    A new system removed all nine PFAS compounds from a municipality's water to non-detect levels in a single pass. Unlike traditional methods, it addresses both long- and short-chain PFAS while generating minimal waste.

  6. Instruments For Environmental Applications 10/29/2021

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

  7. Boost OEE And Find Smaller Metal Contaminants 8/26/2016

    ‘Product effect’ (a phenomenon where the type of product being inspected can itself hinder the inspection technology’s capability to identify a particular contaminant) has long been a problem for food manufacturers. In the case of metal detection, product effect can be caused by a number of factors such as high moisture or salt content, temperature variations, size and shape of the product, orientation through the detector and packaging material.

  8. Case Study: First Municipal-Industrial Water Reuse Project In Virginia! 7/3/2006

    Hampton Roads Sanitation District was created in 1940 to reduce pollution in the Chesapeake Bay. It currently serves a population of approximately 1.6 million with nine regional wastewater treatment plants in Hampton Roads and four smaller plants on Virginia’s Middle Peninsula. HRSD set the goal to reuse its treated wastewater for nonpotable purposes in the 1980s. An oil refinery located next to their York River Treatment Plant approached HRSD in 1996 to supply reclaimed water for the refinery’s cooling and process water. Previously, the refinery utilized increasingly expensive potable water and upgrading its own treatment facilities was too large an investment. In December 2000, HRSD signed a 20-year agreement to provide the refinery with 0.5 MGD of reclaimed water

  9. Identifying Food Contaminants: What Technology Is Best For Your Application? 7/5/2017

    Contaminants are a fact of life for food manufacturers, making contaminant detection systems a necessity. This article explains the process of calculating the ROI of foreign body detection systems.

  10. Saint Paul Regional Water Services Upgrades To Corrosion-Resistant Zinc-Coated Ductile Iron Water Main 8/22/2019

    It is no secret that a large portion of the drinking water infrastructure in the U.S. is near or past its intended design life. Our nation’s water infrastructure needs an overhaul, and the cost of doing so is climbing rapidly. ASCE’s 2017 Infrastructure Report Card graded the nation’s drinking water infrastructure a D. According to AWWA, an estimated $1 trillion is necessary to maintain and expand drinking water service to meet demands over the next 25 years.
