Top 10 Reasons To Choose A Diaphragm Actuated Control Valve

Every water system typically consists of piping networks that distribute water from a source or storage reservoir to the end users. This usually will require some form of a valve that will have to be controlled.

China Power Plant Reduces Capital Costs, Energy Use With New Integrated Membrane System
As engineers come under increasing pressure to reduce maintenance and operating costs, inefficient combination double-pass reverse osmosis and electrodeionization (RO/EDI) water treatment systems have begun to lose popularity as a means of providing ultra-pure water. Integrated membrane systems (IMS), on the other hand, combine multiple membrane-based water treatment processes into a single system. In this case study, find out how a heat and power plant in Northeast China lowered capital costs and energy use by adopting an IMS to replace its conventional water treatment system.
Feeling The Pressure To Reduce Leakage?
Water is a resource that is often taken for granted. As we see the effects of climate change and population growth, the challenges we will face regarding water supply and availability will only increase. Examples of this are beginning to surface extensively in many areas of the world. In Adelaide, Australia, the Murray River has long supplied Adelaide with its source of water however the Murray River has seen extensive overuse for potable, agricultural and industrial use and now combined with changing weather patterns, Adelaide is in trouble. By Brad Clarke, VP of Marketing & Sales, Singer Valve
The Future Of Water Supply In Florida
A majority of water utilities in Florida have historically relied on groundwater for their drinking water supply. In 2010, Florida water utilities used 2.2 billion gallons per day (BGD) of freshwater for public water supply compared to a total of 6.3 BGD used. Groundwater represented 89% of the 2.2 BGD freshwater used for public water supply (USGS, 2013). Fresh groundwater sources at shallow depths have historically been available in abundance By Gerardus Schers, Philip Waller, and Michael Condran, MWH Global

In California, Come Rain Or Shine, Upfront Efficiency Is Always In Style
Caught between a withering drought and floods from winter storms, California faces the worst of both worlds—dealing with scarcity as well as stormwater. America, and much of the world, is watching to see how this trendsetting state handles those challenges. After generations of setting America’s style, from cowboys to Beatniks to Beach Boys to Silicon Valley billionaires, California can set perhaps its most important trend yet—it can lead the way to a more water-efficient America. It has to. The good news is that it can. By Jim Lauria, Senior Vice Director-Water Treatment, Bilfinger Water Technologies
White Paper: Impact Of HTA Dosing On Vent Stream Acidity Of An Acid Dosed MSF Plant As a part of the HTA dosing trial, a vent and distillate sampling system was designed to monitor acidity due to carbon dioxide in the MSF plant. This paper will discuss the results of the HTA dosing trial with respect to the effect on venting and corrosion.
How Larger Flow Meters Speak Volumes
As the price of water continues to increase, errors in flow measurement are magnified for distribution networks that transport large volumes of water. These systems often incorporate meters over 48 inches in diameter, which can be a challenge to calibrate. Learn how choosing the proper calibration method can ensure the most accurate measurements. By Richard Lowrie, Water and Wastwater Industry Specialist, KROHNE, Inc.
Theoretical Operation Of High-Efficiency Ultraviolet Water Treatment Chamber
The NeoTech Aqua ReFleX™ water purification chambers are the most efficient and compact units available today. They require an order of magnitude less energy and less than 25% of the system volume to achieve the same or better purification result as competing chambers. This is the first in a series of three white papers explaining the benefits of these systems. By J. R. Cooper, Ph.D, NeoTech Aqua Solutions, Inc.
Pre-Filtering Multi Media Systems With Automatic, Self-Cleaning Filters Riviera Water District provides potable water for a small community at Clear Lake in Northern California. This lake historically produces significant summer algae blooms and, as a natural lake, has creek sediment runoffs in the winter
Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon
Special precast box culverts were used for one of the most significant segments of the $25.8 million emergency water restoration project, designated by the NRCS, known as the Cache Water Restoration Project (CWRP). The CWRP project involved the reconstruction and improvement of approximately six miles of mostly open, unlined channels that make up the Logan and Northern, as well as the Hyde Park and Smithfield canals. The project incorporated new precast pipeline, box culverts, a section of pressurized pipe, metering systems, turn-outs, head gates, and improved maintenance access.

Application Note: Employing Best Water Quality Monitoring Practices To Reduce Runoff During Construction Under proposed EPA stormwater runoff guidelines, construction site operators will be required to actively monitor or sample stormwater discharges daily. The enhanced effluent rules take effect in August 2011 for construction sites that disturb 20 or more acres and February 2014 for sites that disturb 10 or more acres, and they may stipulate a strict numerical limit of less than 280 NTU for average turbidity (sediment in water) on any day.

Why Engineers Can’t Solve The Water Shortage With Supply-Side Solutions
We are at the point where there is precious little left to dig or dam or drain or pump, and we are going to have a problem explaining that us engineers don’t have all the answers.
Reflective UV Cuts Energy Use By 90%
NeoTech has created a new reflective ultraviolet (UV) disinfection technology that requires only eight lamps— roughly 1/10 of the number of lamps required in similar flow-sized conventional UV systems—and only about 2kw of power.
Decrease Membrane Treatment Capital And O&M Costs With Optimum Flux Rates
Despite a global effort to standardize units of measure to the metric system, the water treatment industry still follows the U.S. trend in resisting that directive by referring to water volumes in treatment plants as gallons per day (GPD). While achieving a specified permeate GPD is certainly important in overall membrane plant design, production capacity has absolutely nothing to do with determining optimal methods of treating site-specific feedwaters and offers no indication of potential membrane fouling rates and related maintenance costs. To evaluate these factors, knowledgeable professionals rely on membrane flux rates as the key consideration in achieving optimal system design and operation. By Harold G. Fravel Jr., Executive Director, American Membrane Technology Association and Karen Lindsey, VP, Avista Technologies, Inc.

The UV Uprising: How UV Disinfection Will Claw Its Way To Prominence
Chlorination in all of its forms — gas, liquid, or solid — has been the primary way for treatment plants to disinfect the treated wastewater. The treatment plants that use gas chlorination must face federal regulatory oversight in the form of a Risk Management Program (RMP). Liquid chlorine plants trade in the regulatory oversight for a more expensive and less effective product. While chlorine in its solid form is good for small treatment facilities known as package plants (named for their mobility). However, ultraviolet (UV) technology is rapidly altering the landscape of disinfection throughout the industry. By Sheldon Primus, MPA, COSS
Has Fracking Gone ‘Green’?
There are few topics more controversial these days than hydraulic fracturing ("fracking"). While the debate rages on as to whether fracking poses a risk to water quality, a new desalination technique addresses two other environmental concerns: water scarcity and greenhouse gas (GHG) emissions. Developed by researchers at the University of British Columbia (UBC), the breakthrough technology uses excess carbon dioxide created in the fracking process to desalinate the process water, making it available for water reuse. It also generates chemicals — hydrochloric acid and carbonate salts — that are valuable for many industrial applications.
