  • Polyfluroalkyl substances, commonly known as PFAS, are man-made chemicals found in many everyday items. You can find them in products such as fast-food wrappers, stain-resistant fabrics, non-stick cookware and firefighting foams, among others. 

    PFAS, including perfluorooctanoic acid (PFOA) and perflurooctane sulfonate (PFOS) - collectively known as PFAS, has been detected in rivers, lakes, streams, aquifers, municipal and private wells, impacting drinking and process water. 

    Based on the newly proposed EPA PFAS National Primary Drinking Water Regulation, Xylem’s MitiGATOR™ mobile system and our permanent treatment systems are capable of meeting the updated requirements. Additionally, the EPA pre-publication notice recognizes granular activated carbon (GAC) and ion exchange resin as Best Available Technologies (BAT) for PFAS treatment.  

    Proven Solutions for PFAS Mitigation

    We are solutions-based, whether you are a municipal customer or an industrial partner. That means we focus on treating PFAS in water rather than selling you a specific product. We provide the most effective solutions based on your water and treatment goals. Whether you need permanent, emergency, mobile, and/or rental solutions, we offer flexible financing options to meet your needs. 

    Municipal Drinking Water Producers
    We offer comprehensive PFAS removal for municipal drinking water applications. From initial discovery and consultation through installation and ongoing operational support, we leverage our expertise and proven success to achieve targeted treatment goals for communities of all sizes nationwide.  

    One notable example is our collaboration with a New Hampshire community, where we worked with the town from testing through installation to ensure their treatment objectives were met. 

    Whether you serve millions or hundreds, we can offer assistance and expertise from the moment you discover PFAS in your water. After reviewing water quality testing results, we can design and deploy pilot tests or rapid small-scale column tests (RSSCT) using the best media suited for your specific water chemistry and treatment goals. 

    What rapid response solutions does Xylem have to mitigate PFAS? 

    • Emergency mobile solutions like our MitiGATOR™ mobile system
    • Short-term rental units 
    • Long-term rental units and lease-to-own 

    If you can’t shut down your contaminated water source, we can respond quickly with emergency mobile units. These can be purchased for long-term use or provide contaminant removal while a more permanent solution is being designed. We also offer short-term mobile units for rent, which can be used on-site for a specific duration, or longer-term mobile placements for projects on a contract basis. 

    As a technology-agnostic provider, we can design the most effective systems to meet or exceed your treatment goals, utilizing a wide variety of media and vessel options. Xylem can partner with municipalities directly and/or engineering firms to seamlessly integrate our solutions into existing systems, tailoring our designs to meet site-specific requirements such as footprint and height. 

    Airports and Military Bases
    Airports and military bases are actively working to remove PFAS and other contaminants from groundwater and soil left from decades of firefighting training exercises. Some states are even awarding grants specifically for PFAS testing and cleanup at airports. We have successful installations on airfields, military bases and within the aerospace industry. Additionally, our soil remediation solutions can be implemented alongside groundwater remediation efforts ensuring
    we meet maximum contaminant levels (MCLs) and other treatment goals.

    Construction and Commercial Dewatering
    For short-term or project-based site remediation related to contaminated groundwater, we offer proven mobile solutions. We can schedule for planned projects or respond to emergency needs with our fleet of mobile assets. From mitigating high water tables to removing contaminants such as PFAS from site groundwater we provide expertise and proven solutions.

    Industrial Water
    Industrial wastewater often requires treatment for PFAS and other contaminants prior to municipal discharge. Among a wide variety of industrial wastewater solutions, we provide ion exchange media and services which mitigate metals and other inorganics as well as contaminants like PFAS. 

    With one of the nation's largest and most versatile mobile fleets, and a wide array of permanent vessel systems we can meet or exceed both treatment goals and expectations across a wide range of municipal and industrial markets.

  • U.S. Pipe’s TR-XTREME® pipe is engineered for seismic resilience, providing the first domestic ductile iron pipeline capable of expansion, contraction, and deflection within a single restrained bell joint.

  • Speed your time to the clinic and create a more potent CAR T-cell therapy with NB-ROC, a xeno-free, serum-free T-cell culture media that can significantly boost transduction efficiency.

  • Access, interact with, and even adjudicate clinical trial imaging from the same platform where you manage all other study data.

Instrumentation
The science of measuring and controlling variables is termed instrumentation. As the name suggests, the process involves using a wide variety of instruments. These are classified as any device that can measure amounts that are physically quantifiable. These instruments do not have to be extremely complex in design. For example, the ruler is an instrument to measure distance, and a simple thermometer measures temperature.
Instruments specific to petrochemical processing include platinum Resistance Temperature Detectors (RTD’s), P/I Converters, many types of level meters, chromatographs, and continuous gas analyzers. These instruments are essential to the day to day instrumentation at petrochemical plants, as it is impossible to gauge to the necessary extent by estimation alone. Human error is inevitable, but an instrument can easily be calibrated or replaced.
Now that you understand the definition of and tools used in instrumentation, you should also understand the necessity of it. Temperature and pressure meters serve to ensure that the environment stays safe for both the chemicals being processed and the employees of the plant. Heat is a very well-documented activator in chemical reactions. If the temperature rises to unusual levels, this could spark an undesired chemical reaction that could prove catastrophic. The flow meter must measure how much oil is leaving the refinery, as it is a very volatile substance. Analytical instruments, such as the chromatograph, analyze the chemical make-up of the refined oil. This allows for the opportunity to make sure that the chemical make-up is correct, giving evidence that the process was correctly completed at all stages of refinement.
