When I look back at 2016 one of the most significant and most satisfying trends I observed was the growing acceptance of ORP measurements, especially to monitor disinfection. To insure the killing of pathogens the measured ORP value provides an unambiguous indicator. The same cannot be said of measuring free chlorine, whose measurement must be combined with pH to determine disinfection efficacy.
The estimated $30-million West Side Loop 48-inch Replacement Project is one of three capital projects being conducted by the Cobb County-Marietta Water Authority to provide additional water to western Cobb County and Paulding County in Georgia. For the project, a 48-year-old, 36-inch pre-stressed concrete cylinder pipe (PCCP) that recently failed is being replaced with 48-inch ductile iron pipe.
The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.
A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.
To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.
The EPA’s guidance documentation “3T’s for Reducing Lead in Drinking Water in Schools and Child Care Facilities: Training, Testing, Telling” recommends for schools to routinely test their facility’s drinking water, with a focus on lead levels in drinking water fountains.
Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.
As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. By Scott Rouse, VP Product Management, Sierra Instruments
Advancements targeting the challenges related to a flooded meter pit environment have occurred slowly over the years, with limited success.
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.
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.
The Siemens Channel Partner in Oregon, has a customer from an engineering firm who also volunteers for Engineers Without Borders (EWB). The Portland chapter of EWB took on a project in Les Anglais, Haiti, to restore their drinking water supply system that had been disrupted in the Fall of 2008.
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.
A municipal wastewater treatment facility located in Louisiana was having problems with a clamp-on ultrasonic flowmeter that was supplied by a Siemens competitor.
