    Primary and secondary sewage treatment are designed to improve the quality of wastewater. These processes reduce bacteria, suspended solids, biodegradable organics, and other materials to improve effluent quality.

  • Lessons Learned From Flint
    Lessons Learned From Flint

    We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly  desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.

ETS-UV™ For Water Reuse ETS-UV™ For Water Reuse

Given the critical shortage of drinking water in many regions, advanced treatment and reuse of wastewater is becoming increasingly common as municipalities address water demands and shrinking supplies.

Veolia Water Technologies has hundreds of power generation references worldwide. Learn more about specific applications for the power industry.

Ultraviolet Disinfection ETS-UV™ Systems Ultraviolet Disinfection ETS-UV™ Systems

Ultraviolet (UV) irradiation is used for multifunctional purposes.  UV is most commonly used as an environmentally friendly alternative to chemical disinfection. It’s one of the most effective methods for inactivating harmful pathogens such as Listeria, E.coli, Giardia and chlorine tolerant pathogens like Cryptosporidium.  UV is also used for removal of organic and inorganic contaminants, including chlorine, ozone and Total Organic Carbon (TOC).  UV used in conjunction with an Advanced Oxidation Process (AOP) will remove Compounds of Emerging Concerns (CEC's), Synthetic Organics (SO's), Endocrine Disruptor Compounds (EDC's) and Personal and Pharmaceutical Care Products (PPCP's), as well as various taste and odor compounds from water.

I-SO™ In-Situ Oxygenation System I-SO™ In-Situ Oxygenation System

What’s the best way to fight odors in the wastewater industry? Add a little oxygen. Adding Praxair’s pure oxygen to your existing process can raise the level of dissolved oxygen enough to reduce odors without further action. Even better, the use of a Praxair oxygen acetates treatment system will lower costs and help you meet your environmental goals. Our systems help you manage peak demand and increase capacity while reducing Volatile Organic Compound (VOC) emissions.

E33 Adsorption Systems E33 Adsorption Systems

In the adsorption process, contaminants break their bond with the water molecules and chemically adhere to a filter media. This is typically accomplished by directing the water flow through pressure vessels containing the filter media at a rate that allows enough contact time for adsorption to occur. AdEdge Water Technologies’ Bayoxide E33 adsorption media is the industry standard for arsenic removal. This granular ferric oxide media reduces up to 99% total arsenic, including both Arsenic (III) and Arsenic (V).

    ORP Sensors – Are They Really The Best Thing “Since Sliced Bread”?

    There have been many publications lately that claim universal appeal of the ORP sensors and their applicability across the board. This concerns me, because the authors sometimes forget to mention some well-known practical limitations of the method, let alone the realities of water treatment applications potentially influencing the sensor performance.

    What’s In Your Water?

    When is the last time you took a moment to stop, and smell your water? A continuous supply of clean and safe drinking water is something that most people take for granted. We rarely go to the tap doubting that the water will be clean and safe. Recently, the general population and water supply professionals have become concerned about the safety and protection of our drinking water supplies.

    Preparing For Algae Season

    For water treatment operators and utility officials, the summer months don’t just mean sunshine, pool parties, and barbecues. The season also brings the peak time for algal blooms, the toxic clouds formed in surface water thanks to increased nutrient contamination and rising temperatures. With rising instances of toxic algae around the country and increased regulations for eliminating it, utilities have had to keep pace.

    For years, I’ve been standing on my deck in San Francisco, looking south to Silicon Valley for innovation in water efficiency. But I’m starting to realize that I might have been gazing in the wrong direction. Maybe I need to turn around and look north, over the spires of the Golden Gate Bridge, toward the Emerald Triangle in Humboldt, Mendocino and Trinity counties, the hotbed of California’s newly legalized commercial cannabis production.

    How To Ensure Your Utility Complies With The LT2

    The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?

  • Carbon Adsorption & Reactivation
    Carbon Adsorption & Reactivation

    Chemical, petrochemical, and oil-refining plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product purification needs, find alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and profitably.
