Automated metering systems (AMSs) or “smart meters” can provide valuable data for electric and water utilities. Data analytics can be used to improve customer service, boost conservation, monitor the system, and even forecast demand. An ultimate goal might be to eventually monitor everything from streetlight intensity to fire hydrants.
When looking for a way to reduce plant operating costs, one of the potentially simplest and often least expensive solutions is to measure liquid and gas flow more accurately. Plant upgrade projects that focus on the continuous improvement of flow measurement and control can trim overall production costs by eliminating waste and reducing maintenance costs.
In recent years, the debate about which technology is best suited for water and wastewater level measurement and monitoring is heating up. There are those who argue that ultrasonic level technology has been uncontested as the standard for level and open-channel measurement applications in the water industry.
Lead in drinking water has become a very visible issue of considerable concern over the last few months. While municipalities across America have been scrutinizing the quality of their drinking water, it should at least be some consolation that manufacturers of measurement instrumentation have taken serious steps to assure that they are not contributing to the problems that have been encountered.
Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant-Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), Cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public.
Pinnacle Ozone Solutions’ new generation of smart Ozone-On-Demand (OOD™) generator and control technology can help significantly reduce the cost and complexity of ozone water treatment.
Khabarovsk Municipal Unitary Enterprise “Vodocanal” (Khabarovsk Vodocanal) provides water supply and sewerage facilities for the city of Khabarovsk in Russia’s Far East Federal District. As part of a program to shift from surface to underground water sources, Khabarovsk Vodocanal constructed the RUB 10 billion Tunguska Groundwater Intake Facilities to deliver 106,000 cubic meters per day (m3/d) of water to the city of Khabarovsk.
A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.
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.
For a pH sensor to maintain an accurate reading, the sensor must remain clean. Specifically, the glass measuring electrode cannot become coated, and the reference electrode assembly must not become coated, plugged or otherwise contaminated by the process solution. Here’s how to clean pH sensors to ensure correct operation.
The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.
In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using MilliporeSigma water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated.
One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.
The water municipality at a mid-size city in the Western region of the U.S. serving a population of about 180,000 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.
The task of managing the quantity and quality of potable water is unimaginable without online instrumentation to help water utilities to measure, treat and deliver drinking water to consumers. ABB’s Aztec 600 colorimetric and ion-selective electrode (ISE) analyzers have been designed to measure the key parameters that affect water quality – aluminium, iron, manganese, phosphate, color, ammonia and fluoride.
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gaining an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas including supply planning, maintenance and resource deployment, leakage detection and rectification and the overall environment, in terms of controlling abstraction and reducing unnecessary draw on natural resources.
There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.
Disinfection is a very important part of the drinking water treatment process, and choosing between an amperometric and colorimetric chlorine analyser is a decision that depends on a variety of factors. Below you will find out why a colorimetric analyser was the right choice for our customer, given their specific situation.
For many utilities, failing pipelines and non-revenue water are atop the list of concerns. However, these issues can be greatly mitigated by leveraging readily available data in an intelligent way — through smart water management.
As manufacturing across the world further develops, new chemicals and contaminant threats are being introduced into the environment, creating new challenges for industrial and municipal treatment operations.
The 7th Annual Smart Water Systems Conference, presented by SMi Group, brought smart water experts from around the world to London for two days in April. As an event partner, Water Online had interview access to event speakers — including those from some of Europe’s largest water providers — who were surveyed on trends and challenges in smart water. Read on to hear the thoughts of four smart water experts on four key questions.
While point level measuring approaches are regarded as simple and user-friendly, they lack the capabilities of more sophisticated continuous measuring instruments.
