Officials from a Pennsylvania county besieged by perfluorinated-compound (PFC) contamination are vowing to take steps to clear the chemical contaminant from their water system.
Just north of Philadelphia, two former Navy sites have been linked to drinking water tainted by harmful chemicals. Since 2014 almost half of public and private drinking wells in Horsham, Warminster, and Warrington, PA, have been shut down because of contamination.
For over 40 years, the Clean Water Act (CWA) has been a primary force protecting our waters and dictating the work of treatment professionals. And, for just as long, samplers have been the tools that allow this work to be carried out. Many plants, however, have yet to embrace the advances in technology that are transforming one of their most fundamental tools. To help usher those plants into the modern age, Water Online spoke with Endress+Hauser about how samplers have evolved to meet changing needs,
A natural gas-fired combined cycle power generation facility located in Idaho contacted QUA to find a solution to improve the performance of a water treatment system used to recycle the plant’s cooling tower blow down water.
The city staff of Buckhannon, West Virginia, recently ran into a situation that didn’t add up. A flow meter at one of the city’s booster stations was indicating a flow rate higher than the capacity of the station’s pumps. The staff contacted the applications team at McCrometer about its flow meter accuracy problem.
Early in 2003, the City of Rome, Georgia, decided to upgrade their Blacks Bluff Waste Water Treatment Plant screening equipment.
Cutting off service to a customer who hasn’t paid their water bill can be a controversial move for many utilities. But a new product that integrates a shut off valve with an ultrasonic meter may make what has traditionally been an all or nothing decision a little easier.
A rural water treatment plant in the Southwestern U.S. treats, stores, and distributes 325,00 gallons per day of water to the village it serves. The village consumes an average of 125,000 gallons a day and can store up to 1 million gallons. Unfortunately, the treatment plant was also losing 210,000 gallons a day due to an unknown leak.
In a time of pervasive drought throughout the Western United States, combined with the relatively newfound ability to account for every ounce of water treated and distributed, it’s no surprise that huge emphasis has been placed on smart, data-savvy metering.
Neptune Benson makes the strong commitment to solve the water treatment challenges faced by our customers.
Due to their critical role in protecting the health of customers, drinking water treatment systems require a high degree of care and oversight.
The Water Research Foundation has released the results of a study testing the most effective method for treating PFOA and PFOS in drinking water.
Here in the post-Flint era of municipal water operations, and for the foreseeable future, the loudest mandate for utilities will be to "get the lead out" of our distribution systems. Until such time that all lead lines are replaced, control strategies will need to be employed.
In the midst of this U.S. presidential race, a thought about Ronald Reagan (apolitical, I promise): Known as the “Great Communicator,” it’s certainly no coincidence that Reagan was an actor before becoming president; and honed communication skills, especially in times of trouble, are vital to effective leadership.
While it took a series of egregious bungles on several different levels to plunge Flint into the crisis, perhaps the most unforgivable lapse has been government officials’ negligent water testing.
This one's not on you, plant operators. Rather than a charge for utilities to aim higher in performance, the latest regulation to impact water treatment operations, as well as others, falls on equipment manufacturers — those who make pumps.
The City of Gordon Texas’s drinking water facility was struck by lightning. Thinking long term, and desiring the latest technology available, the City took this opportunity to upgrade their on-line instrumentation with a range of new continuous monitoring on-line instruments including chlorine analyzers, pH monitoring, temperature monitoring, and turbidity monitoring.
The City of Geneva is located on the Seneca Lake in the wine-producing area of New York known as the Finger Lakes region. The drinking water facility, a Pall 2-train custom Aria™ membrane system, is operated by a team that prides itself in serving the clean water needs of its constituents. Integral to those efforts is the leveraging of tablet technology for maximizing plant operating efficiencies and minimizing downtime.
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.
Monitor for continuous measurement of Ammonium, Nitrate or Fluoride in potable water.
Complete monitoring system for the automatic, continuous measurement of the specific conductivity, concentration of CIP solutions, salinity and TDS in surface water, potable water and cooling water.
The JCS Industries Model 4200EC Gas Vacuum Chemical Feeder mixes and feeds gaseous chemicals commonly used for water and wastewater disinfection accurately, reliably and safely. The system is comprised of a vacuum injector to safely introduce the gas into the feed-water stream, a reversing servo motor coupled with a V-notch valve to regulate the chemical flow rate, and a control module for complete electronic control and communications.
The TETRA LP Block dual parallel lateral underdrain system delivers distribution of air and water during backwashing to enhance filter cleaning and extend run times. TETRA LP Blocks were developed to overcome problems with air/water distribution experienced with other systems.
A food manufacturer in Washington state had a source of well water contaminated with vegetable and fish oils. A five gallon sample was was sent to Kaselco for testing via our electrocoagulation process.
When Flint Michigan discontinued purchasing water from the Detroit Water Authority and began using the Flint River as their raw water source they unfortunately did not consider the potential impact on lead and copper corrosion and the impact on the public.
Process, instrument and plant engineers are challenged continuously by productivity and plant operating efficiency objectives as well as ensuring plant compliance with an ever expanding list of regulations. By Gerardo Vargas, Sr. Member Technical Staff, Fluid Components International (FCI)
A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.
Chlorine dioxide (ClO2) is effective as both a disinfectant and an oxidant in water and wastewater treatment.
It is believed that the legendary Greek physician Hippocrates invented the first bag filter in 500 BC, using it to trap sediment and remove foul tastes and odors from water. Since then, we’ve taken leaps and bounds in our understanding of filtration and how to take specific particles out of water for its many uses.

When machine builders partner with subsystem specialists to simplify and streamline their equipment design, engineering, production, and support, they can save large amounts of time and, in many cases, up to 50 percent of costs — helping to boost profitability and customer satisfaction.
A suburban township in the upper Midwest U.S. buys their drinking water from a major municipal water district. The municipality has many customers and has implemented contracts with each of its wholesale customers that limit the peak flows and the time of day in which they may occur. If the wholesale customer exceeds the limit, they are assessed significant surcharges.
