We are celebrating EarthDay2015 with our freshwater friends! Water covers 70.9% of the Earth’s surface. However, the water found at the Earth’s surface in lakes, rivers, streams, ponds, and swamps makes up only 0.3% of the world’s freshwater sources.
The logo for Redwood City, California reads: “Building a Great Community Together.” Basing their teamwork on an innovative water conservation program, supported by the Sensus FlexNet® communications network, system, city officials and residents are working hand-in-hand to make sure water usage is consumed thoughtfully for the benefit of all residents.
The relationship between the wastewater treatment plant and the community it serves is a delicate one. Unfortunately, politics gets involved because many plant improvements are purchased with municipal bonds.
At a water treatment plant that provides drinking water for distribution to a large area of customers, a contractor decided to switch to SITRANS FM MAG 5100W flowmeters. A local representative saved a the contractor time and money by recognizing the need for the magmeter to be isolated from the piping protection before startup, which also saved the customer from added downtime.
Several years ago, Mueller began a journey to develop a user friendly and cost-effective technology to continuously and remotely monitor pressure at any point within a potable water distribution system. The technology involves threading a sensor onto a corporation valve to transmit pressure readings. The pressure sensor, typically installed two (2) per District Metering Area (DMA), reports at user-defined intervals via cellular service and a Mueller-hosted secure web server. Beginning with pressure monitoring, Mueller has created a communications backbone that utilities can integrate into its monitoring systems or use as a stand-alone monitoring platform. This technology is currently available in North America.
A metallically-pure, stress-free surface provides optimum corrosion protection for wastewater treatment plants. Here’s how to get there.
In 1974 the Congress of the United States passed Public Law 93-523; the Safe Drinking Water Act (SDWA) to protect public health by regulating the nation’s drinking water supply and protecting sources of drinking water. The SDWA first went into effect on June 24, 1977 and has been amended multiple times.
Infraserv Hoechst is a leading company for operating large-scale industrial and chemical production complexes. It is a complete service provider offering services such as purchasing, engineering, and facility management, and it has a full supply of products such as compressed air, steam, cooling water, purified water, technical gases, and energy.
A large gas utility installs a Sensus Auto-Adjust Turbo (AAT) meter for a commercial customer and discovers an unanticipated pile of leaves and other debris in the pipeline.
Xylem TotalCare Condition Audit, an inspection and recommendation program that helps plant operators find ways to lower maintenance costs by identifying inefficiencies in the operation of water and wastewater equipment, was elected to audit the American Canyon Wastewater Treatment Plant (WWTP) in California.
The City of Wilmington, Delaware is situated where the Christina River and the Brandywine Creek flow into the Delaware River.
Faced with aging meters of all kinds from multiple manufacturers, the Etowah Water & Sewer Authority, about an hour north of Atlanta, looked to implement a complete replacement program, one that would not simply replace all existing meters but would also favorably position the Authority for years to come. Specifically, they looked for an advanced metering infrastructure (AMI) solution from one vendor that offered improved accuracy, greater longevity and forward-looking capabilities that would allow them to grow and develop as the future warranted.
Located 30 minutes North-East of Montreal, Canada, the City of Terrebonne has the last drinking water intake of the many cities along the Rivière des Milles-Iles.
High levels of radionuclides (uranium/radium/etc.) in drinking water aren’t very common, but they are very dangerous. If you’ve long dealt with radionuclides, you’re familiar with the treatment requirements — but are you treating as cost effectively as possible?
Ken Krupa of Veolia describes the BIOSTYR DUO, a new technology that combines a biologically active filter (BAF) with a moving bed bioreactor (MBBR) to increase efficiency and reduce facility footprint.
Flow measurement instrumentation options abound, and the challenge of picking the right one for a particular application can be daunting.
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.
When a series of water crises in 2014 disrupted conventional utility services in the coastal Argentine city of Caleta Olivia, the city needed a way to ensure an uninterrupted water supply.
Achieving cost-optimised drinking water distribution, the need to deal sensitively with this valuable resource and to fulfill customer expectations, which include demands for smart metering solutions: the challenges facing water companies are on the increase.
Groundwater is the primary water source for most communities in North America. With an increasing need to provide treatment for a growing list of contaminants, limited support staff, and shrinking operating budgets, water utilities face many hardships. Fortunately, biottta leverages nature to offer an affordable and sustainable solution for wellhead treatment of inorganic and organic contaminants.
Efficient control of microbial populations in municipal wastewater using peracetic acid (PAA) requires an understanding of the PAA decomposition kinetics.
In many countries we take for granted the availability and reliability of safe drinking water. A recent trip outside of the US reminded me of this fact when I saw notices in the hotel rooms stating the drinking water met specific standards and was safe to drink however, my friends from the country emphatically warned me to not drink the water.
The European Commission’s Aerosol Dispensers Directive (ADD) legislation (UN ADR 2013, 75/324/EEC) mandates that aerosol dispensers and small receptacles containing compressed gas (gas cartridges) must pass a leak-proof test before they are transported. Cascade’s CT2211 leak detection system detects and rejects leaking aerosol cans up to a rate of 500 cans per minute. The system is contactless, ensuring minimal product damage or contamination.
Ken Biele, CEO of JWC Environmental, discusses solutions to the growing problem of equipment-clogging disposable wipes.
pH measurement plays an important role in virtually every industrial process and an equally essential part in environmental regulatory compliance. Many of the below questions pop up every day whether in chemical processing plants, power plants, water and wastewater plants or biopharmaceutical processing.
Craig Correia, process automation manager with Festo Corporation, talks about industry drivers for automated systems.
This is the second installment of a three-part series examining wipes in the waste stream. The first installment looked specifically at the growth of disposable wipes usage within the last decade. Now we’ll look at the public outreach campaigns and some of the ways pump manufacturers are adjusting their technology to try to reduce or prevent wipes-related clogging.
The water municipality at a mid-size city in the Western region of the U.S. serving a population of about180,000 people needed to address a chlorine disinfection system problem at one of its water treatment plants.
