In 40 years, Endress+Hauser has become market leader in electromagnetic flow measuring technology
In today’s economic environment when profits are reduced due to rising costs, it is necessary to find ways to save time and money.
A study was conducted by an environmental engineering firm to design a suitable treatment system for the groundwater currently used as the potable water supply for DVI. Reverse Osmosis (RO) was determined to be an effective technology in meeting the applicable standards for water quality.
YSI created this document to address some common problems that are encountered when conducting Biochemical Oxygen Demand (BOD) testing.
Thermal dispersion switches use similar principles as thermal mass flow meters. Fluid carries heat away from the probe tip reducing the temperature difference between a heated resistance temperature detector (RTD) and a reference RTD.
Operations management for a municipal direct water filtration plant reports achievement of a reliable and cost-effective change in chlorination systems that has continued to provide for effective disinfection, while better meeting safety and efficiency criteria. By Cliff Lebowitz
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.
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.
Oxidizing antimicrobials, such as chlorine, are common disinfectants used to treat water. Test strips, DPD kits, and colorimeters are currently the most popular methods for determining the relative disinfecting power of oxidizing antimicrobial agents in these applications. By Myron L Company
Bristol-Myers Squibb (BMS) is a global pharmaceutical and related health care company with the mission to extend and enhance human life. One of the company’s oldest and largest facilities was built in 1943 in East Syracuse, New York, when BMS was one of 12 companies chosen by the federal government to mass produce penicillin.
Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).
Phosphorous promotes eutrophication in surface waters and helps create conditions for algal blooming and oxygen depletion. Some phosphorous removal can occur naturally in a conventional biological wastewater treatment facility, but the result is not reliably compliant with increasingly strict limits on permissible phosphate levels in effluent discharged to receiving streams, ponds and lakes.

Now compatible with the Hach sc100 Controller, the FilterTrak 660 sc Nephelometer connects as a ‘plug and play’ sensor with the universal, dualchannel controller that features an inherent power supply.
The Riviera Grise drains water from the Cul-de-Sac watershed, Haiti, which covers most of the rural areas along the flood plains and areas that extend into steep hillsides. It also covers urban areas of Port-Au-Prince, the capital city of Haiti.
Harmsco® Filtration Products is pleased to offer a solution to the ever increasing blue-algae blooms in water sources. A multi-barrier approach is necessary to physically remove intact (algae and cyanobacteria) before they rupture in the treatment process and then remove extracellular cyanobacteria through adsorption.
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.
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.
Our nation’s record of progress in advancing public health under the Safe Drinking Water Act is significant.
As critical gateways to the Internet of things (IoT), sensors are sure to have a massive social and economic impact globally within the next decade.
Water 4.0 is a concept that has recently been raised as the “future” of the water industry …possibly. Apart from being a paraphrase of Industry 4.0, the questions have to be asked: What is it, and what does it have to do with the way the water industry operates in its current state?
Get to know the basics, best practices, and importance of flow meter calibration from an industry expert.
Part three in our series on the “Pow! emPowering Opportunities in Water” competition from Veolia, The Water Council, and the Wisconsin Economic Development Corporation takes a closer look at winning company WAVVE Stream Inc.
While many companies and investors have struggled to make sense of an entry point into the massive water industry, seeds are consistently being sown for those that know how to monitor and enter intelligently.
Drinking Water Treatment involves the removal of pathogens and other contaminants from source water in order to make it safe for humans to consume. Treatment of public drinking water is mandated by the Environmental Protection Agency (EPA) in the U.S. Common examples of contaminants that need to be treated and removed from water before it is considered potable are microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals and radionuclides.
There are a variety of technologies and processes that can be used to decontaminate or treat water in a drinking water treatment plant before the clean water is pumped into the water distribution system for consumption.
The first stage in treating drinking water is often called pretreatment and involves screens to remove large debris and objects from the water supply. Aeration can also be used in the pretreatment phase. By mixing air and water, unwanted gases and minerals are removed and the water improves in color, taste and odor.
The second stage in the drinking water treatment process involves coagulation and flocculation. A coagulating agent is added to the water which causes suspended particles to stick together into clumps of material called floc. In sedimentation basins, the heavier floc separates from the water supply and sinks to form sludge, allowing the less turbid water to continue through the process.
During the filtration stage, smaller particles not removed by flocculation are removed from the treated water by running the water through a series of filters. Filter media can include sand, granulated carbon or manufactured membranes. Filtration using reverse osmosis membranes is a critical component of removing salt particles where desalination is being used to treat brackish water or seawater into drinking water.
Following filtration, the water is disinfected to kill or disable any microbes or viruses that could make the consumer sick. The most traditional disinfection method for treating drinking water uses chlorine or chloramines. However, new drinking water disinfection methods are constantly coming to market. Two disinfection methods that have been gaining traction use ozone and ultra-violet (UV) light to disinfect the water supply.
