WATER INDUSTRY FEATURES, INSIGHTS, AND ANALYSIS

  • Supporting Innovations To Reduce Nitrogen Pollution From Septic Systems

    Septic systems are common in coastal marine communities on the East Coast of the United States. Septic systems consist of subsurface wastewater treatment structure and use a combination of natural processes and technology to treat residential sanitary waste and greywater from bathrooms, kitchen drains, and laundry. Partially cleaned wastewater is discharged from septic tanks into drain fields, where the water is further treated through biological processes as it travels through gravel, soil, and can eventually reach groundwater. Groundwater linkages with surface waters can then transport any nutrients and contaminants that are present in discharge directly into coastal waters.

  • AFFF Contamination — A Precursor To Long-Term Environmental Hazards

    Although aqueous film-forming foam (AFFF) has been used to save lives, it may be impairing the health of many more. The persistent and pervasive nature of PFAS is again the culprit.

  • Cyanotoxins Treatment Strategies For Water Utilities

    The last couple of years, many newspaper headlines were reporting animal poisonings and deaths, particularly concerning seizure in dogs following drinking from, or just swimming in, water sources contaminated with cyanobacterial blooms. Epidemiological evidence has proven the issue does not limit only to animals, as symptoms of poisoning were detected in humans following consumption of drinking water containing cyanotoxins (cyanobacterial toxins).

  • Plastic Micro- And Nanoparticles In Drinking Water And Foods

    The prospect of plastics working their way into humans is a rising concern for the public, with information presented to them from various, and sometimes suspect, sources.

    Scars from large mining operations are permanently etched across the landscapes of the world. The environmental damage and human health hazards that these activities create may be both severe and irreversible.

  • 4 Benefits Of Electrocoagulation For Arsenic Removal From Water

    In water and wastewater treatment, arsenic is classfied as a heavy metal. It is well known for its toxicity and it can cause numerous health problems in humans if consumed at high enough doses. Arsenic can affect the skin, liver, kidneys, bladder, and prostate as well as the nervous, respiratory, cardiovascular, immune, and endocrine systems. Due to the many health risks associated with arsenic, the U.S. EPA has set the drinking water standard at 10 ppb as the maximum allowable concentration in drinking water. Therefore, this is the goal of all treatment systems for arsenic removal from water.

If not, act quickly, because time to register constructive feedback before the February 12th deadline is running out. Less than three weeks before the end of the comment period, the EPA’s webpage for feedback displayed only 131 public submissions regarding the proposed regulations.

  • Understanding PFAS’ Impact On Remediation Strategies

    For more than 16.5 million water-utility customers in 33 different states, contamination caused by per-and polyfluoroalkyl substances (PFAS) is a source-water issue that will not go away for a long time. What are the practical options for community water systems currently confronting this challenge? Here is an overview of several treatments and their relative successes against a wide variety of PFAS compounds.

  • Preparing To Tackle The Hydra Of LCR Revisions

    As a journalist serving the water industry — but not yet a seasoned technical veteran — I attended a recent Lead In Drinking Water Forum sponsored by AWWA NJ to learn about the challenges of complying with the proposed Lead and Copper Rule Revisions (LCRR). What I heard impressed upon me the technical, administrative, and logistical challenges of delivering safe, lead-free drinking water all the way to user taps. Here are my takeaways.

  • New RO And Other Techniques Lead To Improved Performance

    For water utilities facing various water contamination issues, there is no single catch-all treatment. That is why in this recent Water Talk interview Ronit Erlitzki and Doug Craver of AdEdge Water Technologies share treatment options that can be used alone or in combination to address diverse challenges. They introduce a new reverse osmosis (RO) treatment technique capable of raising recovery rates by 20 percent and reducing concentrate volume up to 70 percent vs. conventional RO (depending on water quality). They also explore biological processes for removing nitrate, VOC, ammonia, etc. and treating high brine concentrations in wastewater, plus techniques for resolving ammonia problems in water with high TOC concentrations.

  • Forward-Looking Technology Anticipates Compliance Needs

    When a company stakes its reputation on delivering innovative technologies, products, and services, the specter of a changing regulatory landscape is considered more an opportunity than an obstacle. In this Water Talk interview, Mirka Wilderer, CEO of De Nora Water Technologies, discusses varying topics such as pharmaceuticals and nutrients in wastewater, the synergy of the company’s new MIOX and Neptune acquisitions, and how to address the growing concern over chlorate disinfection byproducts (DBPs) in drinking water. For example, De Nora’s new ClorTec Gen III onsite hypochlorite generators generate up to 3,000 lbs./day of chlorine-based disinfectants while reducing chlorate formation and cutting operating costs by 15 percent as compared to previously available models.

  • Minimum Liquid Discharge – The Best Bang For Your Buck

    Fresh water sources around the globe are becoming increasingly stressed due to population growth, industry use, and changing climate patterns.  These stresses drive the need to make the most out of every drop of water available.  Water treatment systems inherently produce a waste stream that contains contaminants removed during the treatment process.  This waste stream can often constitute 20-30% of the total water fed to the treatment system, representing a significant loss of a precious resource both in human and economic terms.  Minimizing this waste stream is a key part of the solution to solving the water crisis for both industry and people.
