  • 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 ...

  • 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 ...

  • CBio provides round-the-clock safeguard against illegal levels of ammonia case study

    A market leader in biomass engineering has launched a 24-hour biological safeguard system to protect organisations operating treatment plants against discharging illegal levels of ammonia. North East-based Cleveland Biotech (CB) has seen an increase in enquiries for its Amnite NS5000 product from companies which are obliged to prove to authorities they adhere to legal constraints over their ...

  • 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, ...

  • FAQ - Ammonia Gas Detection Systems

    Please view the full article to find the answers to these questions: Where might hazardous levels of ammonia occur? What ammonia gas detectors are available from CETCI? At what height should ammonia gas detectors be mounted? Where on the ceiling should the ammonia gas detector be located? How many ammonia gas detectors are required? What is a bump test and why should they ...

  • Syntrophy of aerobic and anaerobic ammonia oxidisers

    Deammonification is known as an efficient and resource saving sidestream process option to remove the nitrogen load from sludge liquors. The transfer of the intermediate product nitrite between both syntrophic groups of organisms – aerobic and anaerobic ammonia oxidizers (AOB) – appears very sensitive to process conditions such as temperature, dissolved oxygen (DO) and operating nitrite level. ...

  • Scrubers with a level head

    The available methods for removing pollutants from a gas stream are numerous, to say the least. A popular method, scrubbers allow users to separate gases and solids by allowing the gas to come into contact with a liquid stream. In the end, the pollutants are washed away in the effluent, and the gas exits the system to be used in later processes or to be released into the atmosphere. For many ...

  • 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 ...

  • Nitrifying Bacteria - Koi Carp Ammonia Removal

    A range of nitrifying bacteria - Nitrosomonas (NS) and Nitrobacter (NB). NS converts Ammonia to Nitrite, NB converts Nitrite to Nitrate.

  • Mathematical models and bacterial communities for ammonia toxicity in mesophilic anaerobes not acclimated to high concentrations of ammonia

    In this study, we evaluated ammonia toxicity in mesophilic anaerobic digestion at various pH values and total ammonia nitrogen (TAN) concentrations. We performed anaerobic toxicity assays (ATAs) to evaluate the toxicity effects of TAN and pH on mesophilic anaerobic digestion. Modeling based on the results of the ATAs indicated that the specific methanogenic activity (SMA) decreased by 30% at a ...

  • Time-resolved ammonia measurement in vehicle exhaust

    The objective of this study was to identify the influence of sampling and analytical approach on the quality of NH3 emission data of a gasoline-fuelled three-way catalyst vehicle. NH3 concentration measurements have been performed in the tailpipe and in the diluted exhaust after a constant volume sampling (CVS) system during five different test cycles. Chemical ionisation mass spectrometry ...

  • Innovative system reduces ammonia at Hawick Sewage Treatment Works

    Hawick Treatment Works has reduced its ammonia discharge thanks to an innovative aeration system installed by market leaders Suprafilt. Aeration experts Suprafilt designed a highly efficient system using MF1100 plate diffusers, which increased the amount of oxygen to the site providing an instantaneous reduction in ammonia levels. The company, who are market leaders in designing and ...

  • Banding of urea increased ammonia volatilization in a dry acidic soil

    Volatilization of ammonia following application of urea contributes to smog formation and degradation of natural ecosystems. The objective of this study was to evaluate the impact of (i) incorporation and banding of urea and (ii) surface broadcast of slow-release urea types on NH3 volatilization in a dry acidic soil. Volatilization was measured using wind tunnels for 25 d after standard urea (140 ...

  • 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 ...

  • In-toilet disinfection of fresh fecal sludge with ammonia naturally present in excreta

    A simple treatment method, Safe Sludge disinfection, was developed to disinfect pathogens in fresh fecal sludge using the ammonia naturally present in excreta. In the first step, urea is hydrolyzed to ammonia (NH3/NH4+). In the second step, Ca(OH)2 is added to raise the pH level such that NH3, a known disinfectant, is the dominant form of ammonia; ...
