    Calgon Carbon Initiates Emergency Response To PFAS Detection

    Blades, Delaware, a small town in Sussex County, provides drinking water to more than 1,300 residential and business locations throughout the community. In 1981, the citizens of Blades voted to improve their water and sewage facilities by establishing a central water supply and tying all properties into the nearby Seaford Sewer System. By February of 1982, the project was complete and since then the town has had a clean and safe municipal water supply.

    WRF Hosts Capitol Hill, State-Of-The-Science Briefing On Harmful Algal Blooms

    To make informed decisions about how to limit exposure to cyanotoxins, utilities need information to select and implement a comprehensive and technically sound management approach. The Water Research Foundation (WRF) has been actively involved in developing effective innovative solutions to help utilities address this challenge and protect public health.

  • Analyzing Water Quality Parameters When Choosing AOP Systems For Water Treatment
    Analyzing Water Quality Parameters When Choosing AOP Systems For Water Treatment

    In water and wastewater treatment, chemistry is king. Treatment options are evaluated depending on the quality of water to be treated and the treatment application. Treatment systems including AOP systems, are designed to specifically target certain contaminants and remove or reduce them from the water. This takes places through the power of chemical reactions. Even biological treatments involve chemistry at their core.

  • Benefits And Disadvantages Of The Advanced Oxidation Process
    Benefits And Disadvantages Of The Advanced Oxidation Process

    In many water and wastewater treatment applications, there are a number of pollutants that are difficult to reduce by physical, chemical, or biological means alone. In more recent years, there has been a growing concern regarding pharmaceutical drugs in drinking water and aquatic environments. Pesticides get caught in runoff from farms into freshwater supplies.

    Disinfection Tech Trials: How Calcium Hypochlorite Feeders Won Over Long Beach Township WTPs

    In 2012 Long Beach Island, New Jersey, was pummeled by the catastrophic storm surge of Hurricane Sandy. Three of the town's four water plants were badly damaged. Plans were made to rebuild the facilities to higher standards to withstand potential storm impacts. 

  • EPA Outlines Possible Solutions To Looming Perchlorate Limits
    EPA Outlines Possible Solutions To Looming Perchlorate Limits

    The U.S. EPA is gearing up to limit perchlorate in public drinking water systems, so municipalities should start preparing to adopt the appropriate testing and treatment technologies. In a recent report, the agency identified several technologies as the best available to address the perchlorate problem.

  • The U.S. Drinking Water Supply Is Mostly Safe, But That's Not Good Enough
    The U.S. Drinking Water Supply Is Mostly Safe, But That's Not Good Enough

    Most Americans take clean drinking water for granted as a convenience of modern life. The United States has one of the world’s safest drinking water supplies, but new challenges constantly emerge.

  • Ridgway WTP Saves 20-30% With Real UV254 Analyzer
    Ridgway WTP Saves 20-30% With Real UV254 Analyzer

    The Ridgway Water Treatment Plant (WTP) in Elk County Pennsylvania uses a Real Tech Real UV254 online analyzer to achieve a 20-30% savings in annual coagulant use in their conventional water treatment process. Beyond operational cost savings, the Real UV254 system helps the WTP consistently produce high quality drinking water for the town’s 1700 customers.

  • Granular Activated Carbon System Provides Emergency Solution To Combat Algal Toxins
    Granular Activated Carbon System Provides Emergency Solution To Combat Algal Toxins

    Nestled in the Finger Lakes region in upstate New York, the town of Owasco is a popular vacation spot. With about 4,000 residents, the town, along with the nearby community of Auburn, relies on Owasco Lake for its drinking water. In 2016, Owasco and Auburn detected algal toxins in their finished water for the first time. With the busy summer tourist season quickly approaching, GHD contacted Calgon Carbon.

  • On-Site Sodium Hypochlorite Generation Maintains Consistent Chloramine Disinfectant Residual At A Remote Tank
    On-Site Sodium Hypochlorite Generation Maintains Consistent Chloramine Disinfectant Residual At A Remote Tank

    Purissima Hills Water District (PHWD), a county water district, provides chloraminated water service to two-thirds of the town of Los Altos Hills, adjacent to the city of Palo Alto in Northern California. With remote tank locations, low population density (6,800 people) and low water demand (1.61MGD), PHWD is constantly challenged to maintain consistent disinfectant residual levels while simultaneously balancing the safe delivery of chemicals to its tank site at an affordable cost.

  • Oxelia Oxidation-Enhanced Biologically Active Filtration For Drinking Water

    In the battle with hard-to-treat contaminants, drinking water just got a powerful new ally. Leopold Oxelia™ oxidation-enhanced biologically active filtration system.

  • SMART Disinfection

    Over 70% of the Earth’s surface is covered with water, about 60% of water makes up a human being. One single person consumes more than 30,000 gallons of fresh water a year on average.

  • SORB 33® ARS Series Arsenic Removal Systems – Pre-engineered For Faster Delivery And Simple Installation

    De Nora’s SORB 33® arsenic removal adsorber systems use our proven and effective arsenic removal media that removes arsenic to non-detect levels. Systems are pre-engineered for faster delivery times and simple installation.

  • WEDECO LBX e Series UV System

    WEDECO LBX e UV system is a compact closed vessel UV reactor for drinking water, wastewater, water reuse, and WEDEO’s MiPRO Advanced Oxidation Processes (AOP) applications. Equipped with WEDECO’s low-pressure, high output amalgam ECORAY® UV lamps and OptiDose sensor based control, the LBXe provides the highest operating efficiency with low life-cycle costs. Additionally, the LBXe reactor’s extensive validation envelope ensures disinfection performance over a range of UV transmittance (UVT) values, flowrates, and a variety of target organisms.

  • 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).

A Tradition Of Advanced Disinfection Continues (Video) A Tradition Of Advanced Disinfection Continues (Video)

Trojan Technologies has been providing treatment solutions for the water/wastewater market for four decades, but 2018 stands out as the year Stephen Bell joined as its new president. Water Online had opportunity to catch up with Bell at WEFTEC, where he talked about the company's culture, philosophy, and drive to innovate. One particular innovation is the TrojanUVFlex, a drinking water disinfection and advanced oxidation system for both potable and non-potable reuse applications, as well as the destruction of chemicals such as 1,4-dioxane. Tune in for an introduction to Bell and a summary of Trojan's unique technology.
