  • 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 ...

  • 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, ...

  • 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 ...

  • 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 ...

  • 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 ...

  • NEO Monitors conquers the Quasi-impossible

    China is a world factory powered by its abundant coal resource. China is facing a huge environmental challenge brought together with the fossil-fired power plants. China has therefore been conducting technical retrofit to the engines of its economy, by introducing emission control facilities. Selective Catalytic Reduction (SCR) technology is one of the most widely applied emission control ...

  • 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 pH and ORP in a SHARON reactor

    This paper analyses the valuable information provided by the on-line measurements of pH and oxidation reduction potential (ORP) in a continuous single high ammonia removal over nitrite (SHARON) reactor. A laboratory-scale SHARON reactor equipped with pH, ORP, electric conductivity and dissolved oxygen (DO) probes has been operated for more than one year. Nitrogen removal over nitrite has been ...

  • 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 ...

  • 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 ...

  • 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 ...

  • A preliminary review of gas-to-particle conversion monitoring and modelling efforts in the USA

    Ammonia and inorganic acid gases emitted from livestock and poultry operations, manure treatment, handling and application can affect air quality by the formation of secondary fine particles. The process of gas-to-particle conversion (GTPC) of relatively short-lived gaseous ammonia to more persistent fine particles can affect local and regional air quality far away from the agricultural sources. ...

  • 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 ...

  • Online Process Analyzer Installed at F.J. Horgan WTP to Monitor Chloramination

    Construction was completed on the City of Toronto's F.J. Hor-gan Water Treatment Plant in 1979, more than 60 years after chloramine had first been used to disinfect drinking water in an Ottawa plant. By then there was little debate about the benefits of chloramination and it was incorporated into the new plant's design as part of the disinfection process. Chloramine is more stable than free ...

  • 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 ...

  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...
