North Carolina lawmakers are debating whether to use state or federal standards when deciding to alert residents about dangers in their drinking water.
Electricity is a major cost for industry operations, and the cost of meeting environmental regulations is right up there as well. At the same time, industries are compelled to improve sustainability and lower their carbon footprints.
As outlined in earlier articles, increasing public awareness or even seeking legal action are potential tools to help municipalities gain control of the wipes problem. However, many agencies have seen that these strategies are not completely effective in the long term, and they must also employ new technologies to permanently deal with the wipes epidemic.
On-site sodium hypochlorite generation is a proven, cost-effective, reliable and safe alternative disinfection treatment method. On-site generated sodium hypochlorite is stable and easy to feed, and less chlorine is lost to the atmosphere because of better mixing and retention in the treated water.
A contractor for San Jose Water Company in San Jose, California, has taken delivery of more than 3,000 feet of zinc-coated iron pipe from AMERICAN Ductile Iron Pipe, making it among the nation’s first utilities to install zinc-coated pipe.
Savannah Mitchell felt her heels sink into the moist, mushy ground and was glad she’d changed into her serviceable, waterproof wellies.
Ken Biele, CEO of JWC Environmental, discusses solutions to the growing problem of equipment-clogging disposable wipes.
The City of Bloomington’s water purification plant has been operating since 1929. The lime-treated water has high pH which can cause scaling and can eventually clog the piping and filters in the plant. So, the plant needs to re-carbonate the water thereby lowering and stabilizing the pH. CO2 is an effective and safe chemical that offers treatment flexibility for a utility doing pH control.
FCI’s NuTec FS2000 flow and LS2000 level insertion switches represent the first thermal switches designed with 2-wire (loop power) 4 mA to 20 mA. Using 24 Vdc input power, this design allows for retrofitting existing failure prone mechanical float and paddle switches without wiring modifications. An alarm with SPDT relay and input power of 100 Vac to 240 Vac, 24 Vdc or 24 Vac is also available. Fluid Components International
Siemens Process Industries & Drives Division is pleased to announce independent certification of performance for its Magmeter products in less than ideal mounting conditions.
Fire Rescue TV produced a video Mueller Co. that provides a rare look inside the company’s fire hydrant plant in Albertville, Alabama.
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.
Name a contaminant, any contaminant, and chances are that the U.S. EPA’s new reference tool has you covered — or at least soon will. The recently revamped Drinking Water Treatability Database is set to include more than 200 contaminants, with detailed information on what they are, where they come from, and how to get rid of them.
SCADA implementation or enhancement is a collaborative process. One of the hardest challenges is keeping up-to-date on the latest features available and determining whether or not the new benefits offset the cost of implementation.
This document presents the available options for variable connections of the Liqui-Flux® W – module types W08, W10 and W20. Download the datasheet to learn more.
Due to their critical role in protecting the health of customers, drinking water treatment systems require a high degree of care and oversight.
This edition of Disinfection Digest discusses the discharge limit of peracetic acid (PAA) into the environment and the incorporation of dilution factors in the assessment of a site-specific, risk-based residual PAA concentration in wastewater effluents.
The city of Yakima services approximately 19,000 accounts within 27 square miles in the Yakima Valley.
During the cold winter, the Quebec region enters a deep freeze, with temperatures often reaching -25 degrees Celsius.
A milk producer operates an evaporated milk production facility that generates an average of 58,000 gpd of contaminated water with spikes of 1,200 gallons up to 12 times per day. Two 2,000 gallon batch tanks are used for pH adjustment before discharge. Most of the flow goes through the tanks.
Accurate partially-filled pipe measurement is essential when dealing with variable stormwater flows or over-sized community systems built for future growth. In Europe, new stormwater regulations requiring treatment before release are driving a change in measurement that will likely be seen in the U.S. in the not-too-distant future.

This year at WEFTEC in booth #3648, Smith & Loveless continues its legacy of wastewater pumping innovation with the announcement of the EVERLAST™ Wet Well Mounted Pump Station series.
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.
Brazos Electric Cooperative Power Plant in Cleburne, TX is a nominal 258 MW combined cycle gas fired power plant operating on AGC (Automatic Generation Control) load requirements. The plant uses approximately 54 million gallons of water per year for boiler feed water and NOx control of its combustion turbine.
Living near water requires that we plan for situations when we have too much of it. Throughout history we have dealt with flooding when weather events exceed “normal” parameters.
Supervisory control and data acquisition (SCADA) systems are the digital pulse of water and wastewater treatment plants. Serving as the information hub, SCADA makes the most of the day’s cutting-edge technology and in turn uses it to make the most of the plant’s operations. But how to keep up with a system that evolves as quickly as the greatest minds in the field will allow?
It has been named one of the Seven Modern Wonders of the World with about 14,000 cargo ships passing through its two locks every year. In 2016, its wonder will expand as a third set of locks opens and Post-Panamax ships pass between the Atlantic and Pacific Oceans for the first time.
