  • Anglian Water selects Proam ammonia monitor

    Anglian Water (AWS) has selected the Proam ammonia monitor to provide continuous ammonia measurement on final effluent discharge where accurate and reliable measurement is required. One of the most recent installations is at Stanningfield WwTW situated near Bury St. Edmunds, in Suffolk. This is a small rural site receiving primarily domestic sewage. The site performs aerobic ...

  • The Wonders of Ammonia & Chlorine

    The two most common chemicals found in your home, office and commercial facilities in one form or another are Ammonia (NH3) and Chlorine (Cl2). They are also two of the oldest and most widely produced chemicals in commercial use around the world. Ammonia, a refrigerant by “nature” Refrigeration by mechanical means goes back to the 1800s and ammonia was among the earliest chemicals to ...

  • Detection of moisture in ammonia gas

    Problem Statement As technologies advance, so does the request for ultra high purity ammonia. Ultra high purity (UHP) ammonia is used in the semiconductor industries, production of flat panel displays, and a number of other applications. Due to this rising interest in UHP ammonia, manufacturers are having to battle ammonia’s most prominent and damaging impurity--moisture. For ...

  • Ammonia Vent Line Gas Detector

    The LPT-A Vent Line Ammonia Transmitter (P/N: LPT-A-VLT-NH3-S) is designed for continuous monitoring of ammonia levels in the vent lines of refrigeration systems caused by equipment failure or system over pressurization. Slow leaks of refrigerant can be costly over time and a dangerous situation could present itself if a high pressure release were to occur. The VLT provides continuous, ...

  • BUMP TESTING AMMONIA (NH3) SENSORS

    Bump testing a gas sensor involves flowing a concentration of gas that is slightly higher than the Low alarm setpoint of the gas detector for a short period of time (1-2 minutes or less). The purpose of a bump test is to confirm that the sensor responds to the presence of gas, the low alarm will activate and the gas detector overall ...

  • A short-term investigation using In-situ ammonia monitoring at a WWT, M Keown Severn Trent Water

    Summary: Two separate inlet streams are received for treatment at this works, one being predominantly domestic in origin and the other being predominantly industrial, arising from a local dye works. Their treatment is kept completely separate with municipal stream being subject to preliminary treatment, primary settlement, and secondary treatment in surface aerated activated sludge ...

  • Ammonia sanitisation of sewage sludge using urea

    The aim of the study was to develop a simple, low-cost treatment for sewage sludge using urea as a sanitising agent. Sewage sludge was spiked with Enterococcus faecalis and Salmonella typhimurium, treated with 0.5, 1, 1.5 and 2% w/w urea at laboratory scale, and the viability was monitored during 4 months of storage at 4, 10 and 22 °C (only 0.5%). A ...

  • Implementation of an automatic and miniature on-line multi-parameter water quality monitoring system and experimental determination of chemical oxygen demand and ammonia-nitrogen

    An automatic, miniature and multi-parameter on-line water quality monitoring system based on a micro-spectrometer is designed and implemented. The system is integrated with the flow-batch analysis and spectrophotometric detection method. The effectiveness of the system is tested by measuring chemical oxygen demand (COD) and ammonia-nitrogen in water. The results show that the modified system ...

  • Minimizing ammonia consumption in DeNOx plants – Case Study

    Flue gas denitrification Combustion processes result in emissions that can be harmful to the environment, in particular carbon dioxide (CO2), sulfur dioxide (SO2), nitric oxides (NOx), and dust. Therefore, measures are implemented in power stations and other plants comprising combustion processes to reduce emissions. For flue gas denitrification, besides front-end primary ...

  • Monitoring for the golden balance

    On Herøya in Porsgrunn, Yara has an ammonia plant, three nitric acid plants and a calcium nitrate plant. Together the plants produce a wide range of fertilizers that meet the requirements for fertilization ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Low-pH Ammonia Oxidation at a Biological Nutrient Removal Facility

    ABSTRACTMcAlpine Creek Wastewater Management Facility (MCWWMF), owned and operated by Charlotte Mecklenburg Utilities (CMU) of Charlotte, North Carolina, is permitted to treat 64 million gallons per day (mgd). Along with MCWWMF, three CMU treatment plants discharge effluent into the Catawba River just upstream of the South Carolina border. CMU worked with North and South Carolina regulators ...

  • Fast Response, Early Boost: Eliminate Ammonia Oxidizing Bacteria

    Potable water storage tanks in chloraminated systems endure water quality problems, particularly during warm weather. A simple approach can solve these problems, enhance a facility's mixing system, and save money. Historically, attempts to solve water quality problems in chloraminated systems that use water storage tanks have been minimally successful. Many storage tank facility managers have ...

  • How NoMonia Works to Treat or Remove Your Ammonia - Case study

    Most water utilities should have effective treatment methods for the filtration of arsenic, iron and manganese from drinking water sources. However, as ammonia becomes increasingly concentrated in groundwater throughout the U.S., many utilities around the country are searching for ways to successfully treat the contaminant, while also meeting U.S. Environmental ...

  • PureAire Universal Gas Detector Offers Protection Against Toxic Levels of Ammonia

    In March of 2016, an ammonia gas leak at a seafood processing plant in Boston left one worker dead. The fumes at the plant were so powerful that firefighters could not promptly enter the scene to mitigate the gas leak and try to save the staff member until much later. Reports show that 5,300 pounds of ammonia gas leaked out of the plant. If you work with ammonia at your facility, learn ...

  • Pollution monitoring in Cement Industry

    The rising use of waste based fuels in the cement industry, both for economic and Environmental objectives, combined with the strengthening of air emission regulations around the world is pushing many operators to face a wider list of pollutants to monitor this, with associated costs. The design of appropriate solutions meeting local regulation is the key to maximize the cost benefit of the fuel ...

  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...
