	Boost Capacity and Efficiency, While Minimizing Upgrade Costs in Water Treatment Plants Many Water and Waste Water Treatment Plants (W/WWTP) are facing increased demand, but are limited by capacity and/or input power. Also, the cost of electric power is a major portion of operating expense in these facilities. This paper covers two related topics. First is a case study ...
	How Payment Technology Can Improve Cash Flow Utilities and municipalities today want to simplify bill payment for customers. One way to do this is to make it easier for customers to pay with cash. Until recently, many of us thought cash would eventually be replaced by electronic payment methods. Yet there are still an estimated 68 million a...
	Heavy Metals Water Testing - Powered by DNA Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants -- such as uranium, lead, copper and mercury -- are one prevalent type of water pollutant. They are persistent in the environment once discharged and removal from source waters is n...
	The Effectiveness of Total Organic Carbon (TOC) as the Defining Test for Wastewater Treatment Plants As urban communities continue to grow, wastewater treatment facilities must grow with them. To meet the demands of the 21st century, quicker, more accurate testing with fewer sources of error must be employed. Traditionally, carbonaceous biochemical oxygen demand (CBOD) has been the defining test...
	How Larger Flowmeters Speak Volumes Water is money and the price of water is increasing all over the world. As a result of these price increases, it is necessary for the water industry to have the most accurate methods of flow measurement available. In large distribution networks flow meters over 48 inches in diameter m...
	Remote Diagnostics Will Reduce Service Costs and Increase Uptime of Filtration Systems Productivity is more reliable when equipment can be monitored to detect incipient failures and take corrective action before the plant goes down. But many devices, such as analog control valves, pneumatic valve terminals and field sensors, often do not offer diagnostic feedback, or it is not bein...
	Why mix? How active mixing maintains water quality in potable water storage tanks Drinking water treated with either chlorine or chloramines will normally remain stable and safe for a few days in storage. Operators typically rely on normal cycling of water in and out of the tank to keep the water mixed to limit aging and deterioration of disinfectant chemicals. However, this “...
	BioGas Flow Measurement Challenges and Solutions KROHNE has successfully deployed its flowmeter solutions for many applications throughout the world to deal specifically with the growing demands for accurate biogas flow measurement in a wide and seasonally varying operational range. This paper presents two specific stories that highlight ...
	Smart Water Networks Every time your utility gathers, treats, and distributes water — every time a pump starts, every time a tank is filled, every time a tap is opened — you are also generating and distributing data. In general terms, each and every water management activity creates data that can reveal valuable netw...
	Control and Consequences: Reduce Consequences, Reduce Risk, Save Money America's aging water systems are in need of repair and replacement. Indeed, the American Water Works Association estimates replacement needs of $526 billion over the coming years, while the EPA estimates over 240,000 main breaks each year. The cost of system replacement places extensive financia...
	GRAND RAPIDS SAVES 15% WITH THE RTC-NITRIFICATION SYSTEM The city of Grand Rapids is saving energy and money for its residents after installing a Hach Real-Time Control System in its wastewater treatment plant, receiving a $58,728 rebate check in 2013 from their local public utility, after upgrading the wastewater treatment plant’s aeration system, inc...
	What Makes an Effective Odor Control Cover System Design? A common side effect of wastewater treatment processes is the unpleasant odor that can linger near the plant. Neighbors, offended by the odors, expect a resolution. This white paper examines potential solutions to the odors produced by wastewater treatment plants and presents specific considerat...
