Achieving consistent water pressure is a challenge for geographical areas that have grown faster than the development of infrastructures to accommodate water demand and for businesses such as fast food restaurants and strip malls.
When I look back at 2016 one of the most significant trends I observed was the growing acceptance of ORP measurements, especially for monitoring disinfection. With one caveat, the ORP value measured in a solution provides an unambiguous measure of the disinfection efficacy.

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.
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
Employing roughly 5,000 workers in 12 countries, Vandemoortele bakery and production plant owes its success to high standards of quality, innovative production technologies, and a flair for finding economic alternatives. The latest example is the SITRANS FC430 Coriolis flow meter.
A WWTP sought solutions to improve process control, as high centrate solids caused plant inefficiencies such as high wasting rates, inefficient capacity and loading, and stress on centrifuges. Read the full case study to learn how the RTC-SD solution controlled polymer dosing in real time, allowing the WWTP to improve solids capture and increase throughput.
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.
Wastewater treatment can be a dirty job — but someone has to do it. At a Canadian wastewater treatment plant (WWTP) serving around 75,000 citizens, between 240 and 300 cubic meters of digested sludge are treated each and every day!
The Rahway Valley Sewerage Authority (RVSA), which operates a large wastewater treatment plant in New Jersey, embarked on a green co-generation waste-to-energy project to power a portion of its operations. The plant’s management team became interested in pursuing the gas-to-energy power co-generation system for both environmental and cost reasons.
A municipal wastewater treatment facility located in Louisiana was having problems with a clamp-on ultrasonic flowmeter that was supplied by a Siemens competitor.
A large east coast water supplier faced a number of challenges with one of its pumping stations. It was built more than 35 years ago on a 25’ earth mound (“ant hill”) to protect it from flooding, the pumping station was becoming very expensive and inefficient to operate.

Process instruments are used widely in water and wastewater treatment plants to monitor the effluent quality. However, their applications are not limited to monitoring effluent quality. These water and wastewater quality monitoring devices can be applied throughout the network of collection, treatment, and disposal
Instrumentation can give guarantee of proficient treatment processes of water quality parameters such as turbidity, pH, ORP, conductivity and dissolved oxygen. Instrumentation is done in the following aspects.
Measurement Techniques include, Gravimetric analysis or, simply, weighing, Colorimetry or spectrophotometry, Titration, and Mass Spectrometry:
Platforms on which instrumentation can be carried out include
Some of the instruments used in water management are:
