Misinformation about WirelessHART networks prevails among many instrument engineers in the process industries. This article attempts to set the record straight by debunking seven myths about these networks.
Well on the way to becoming a total environmental monitoring solutions provider, Alam Sekitar Malaysia Sdn. Bhd. has applied its expertise in air and water quality monitoring to aid the Malaysian government in safeguarding the nation's water supply. A broad contract between ASMA and Malaysia's Department of the Environment partners the two entities in a highly efficient system that gathers long-term trend data on water quality while also maintaining an early warning system to alert officials and water treatment operators of pollution discharges in key reaches of the country's river 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.
In February of 2014, due to severe drought conditions, the Federal Bureau of Reclamation informed central California farmers that they would receive no irrigation water from the lakes, canals and reservoirs under the Bureau’s control.
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 municipal wastewater treatment facility located in Louisiana was having problems with a clamp-on ultrasonic flowmeter that was supplied by a Siemens competitor.
Water is a precious resource! Now, more than ever, businesses and facilities must take charge of their water usage to help with water conservation and lower water bills.
Through the implementation of a WAGES (Water, Air, Gas, Electricity and Steam) monitoring solution, a brewery was able to optimize energy and resource usage while boosting capacity to meet the demands of U.S. customers. Water usage costs were reduced by 28%; the brewery’s carbon footprint was reduced creating a savings of $2 million/year from CO2 recovery; compressed air usage was reduced by 15%; and fuel oil costs were reduced by $34,000.
Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.
The amount of insoluble matter present in drinking water is an essential quality indicator. Silt, sand, bacteria, spores, and chemical precipitates all contribute to the cloudiness or turbidity of water. Drinking water (DW) which is highly turbid can be unpalatable and unsafe. Consumption of even low concentrations of certain bacteria and other microorganisms can cause serious health effects. Consequently, an accurate and sensitive measurement of turbidity is vital for ensuring that drinking water is free of these contaminants.
Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
Electrical conductivity is the most convenient method for testing RO water quality and membrane performance. Pure water is actually a poor electrical conductor. The amount of ionized substances (salts, acids, or bases) dissolved in water determines its conductivity. Normally, the vast majority of the dissolved minerals in tap, surface or ground water
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.
Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.
Though they all must support routing functionality, some devices do it better than others.
Routing consumes more energy, so the lifetime of the battery will be affected. Therefore, a device with a battery that is inexpensive, has a long lifetime, and is easy to change would be ideal. With all this considered, a WirelessHART temperature transmitter is a suitable option to operate as a repeater.
Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.
The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.
What’s the right flow measurement method for your operation? A leading independent lab breaks down the options and considerations.
Last week, a two-inch thick, ductile iron section of a water main broke and flooded a densely populated part of downtown Boston — sparking manhole fires, deluging businesses, and snarling traffic while utility crews rushed to repair the ruptured main.
A new initiative will test the theory that some of the next great water technologies are right under our noses, without us even realizing it.
DNA sequencing can provide more information on water and wastewater than traditional methods. Is it time for treatment operations to adopt the method?
The U.S. EPA lends advice on how small systems can combat increasingly troublesome PFC contamination.
