  • 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.

  • Engineers use Autodesk InfoWater® Pro software to model water distribution systems in an easy-to-use GIS interface.

  • Setting a New Benchmark for Ease of Operation

    The NP-255 is a robust tablet press that was built to meet even the most demanding needs of the mid-sized tableting industry. The press has features and options designed to increase production, improve tablet quality, reduce waste, and set a new benchmark for ease of operation. Designed, engineered, and manufactured in the USA, this unique machine has a maximum production speed of 192,000 tablets per hour.

    With a hardened steel die table, a gravity feeder that is interchangeable with a two-paddle forced feeder, and our industry-leading intuitive Natoli AIM™ ProPluscontrol system, the NP-255 is the new standard for value in the mid-sized tableting industry.

  • Ideal for small batch sizes, many format changes, or a wide variety of packaging materials – the BE4 reliably meets all requirements. It enables a highly efficient process thanks to the two-lane operation with a very small footprint. Thanks to the 100% modular concept of the Blister Expert platform, the BE4 can be upgraded to a high-speed solution at any time.

  • World's first real-time drinking water quality monitoring sensor for smart water meter. Online membrane integrity monitoring sensor for every vessel.

About Nutrient Removal

Nutrient removal from wastewater consists of treating wastewater to remove nitrogen and phosphorus before it reenters natural waterways. High levels of nitrogen and phosphorus in wastewater cause eutrophication, a process where excess nutrients stimulate excessive plant growth such as algal blooms and cyanobacteria. The decomposition of the algae by bacteria uses up the oxygen in the water causing other organisms to die. This creates more organic matter for the bacteria to decompose. In addition, some algal blooms can produce toxins that contaminate drinking water supplies.

As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program regulates point sources, such as municipal wastewater treatment plants, that discharge pollutants as effluent into the waters of the United States. In recent years, many of the States’ environmental bodies have lowered nutrient limits to arrest eutrophication. Maryland’s effort to protect the Chesapeake Bay and its tidal tributaries is perhaps the most notable example of nutrient removal in the US. Nutrient removal continues to be a growing area of focus for wastewater treatment throughout the world.   

The removal of nitrogen and phosphorus require different nutrient removal processes. To remove nitrogen, the nitrogen is oxidized from ammonia to become nitrate through a process called nitrification. This process is then followed by denitrification where the nitrate is reduced to nitrogen gas which is released to the atmosphere and removed from the wastewater.

Nitrification is a two-step aerobic process which typically takes place in aeration tanks. Denitrification requires anoxic conditions to encourage the appropriate biological conditions to form. The activated sludge process is often used to reduce nitrate to nitrogen gas in anoxic or denitrification tanks.

Phosphorus can be removed biologically using polyphosphate accumulating organisms (PAOs) which accumulate large quantities of phosphorus within their cells and separate it from treated water. Phosphorus removal can also be achieved by chemical removal. Once removed as sludge, phosphorus may be stored in a land fill. However, many municipalities and treatment facilities are looking to resell the biosolids for use in fertilizer.
