  • 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, ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Nitrogen removal and ammonia-oxidising bacteria in a vertical flow constructed wetland treating inorganic wastewater

    Nitrogen removal performance and the ammonia-oxidising bacterial (AOB) community were assessed in the batch loaded 1.3 ha saturated surface vertical flow wetland at CSBP Ltd, a fertiliser and chemical manufacturer located in Kwinana, Western Australia. From September 2008 to October 2009 water quality was monitored and sediment samples collected for bacterial analyses. During the period of study ...

  • The Use of Oxidation-Reduction Potential as a Means of Controlling Effluent Ammonia Concentration in an Extended Aeration Activated Sludge System

    ABSTRACTThis study developed a strategy to control effluent ammonia from an activated sludge system, using oxidation-reduction potential. By controlling effluent ammonia concentrations, disinfection of treated wastewater is more cost effectively achieved by chloramination rather than break-point chlorination. The system under consideration was an extended aeration oxidation ditch. The study takes ...

  • Major waste management company and cleveland biotech combine resources to resolve a breach of ammonia consent in a large wastewater treatment plant case study

    The WWTP itself is located in the East Midlands, and treats dairy waste from a large processing plant, treating c1,500m3 of effluent per day. On 30th July the ammonia (NH3) levels in the permeate from the MBR at the plant began to increase. The effluent plant discharges to a river and as such, the consent limit is stipulated by the Environment Agency at 4mg/l. Within three days, the ammonia ...

  • 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 ...

  • 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 ...

  • 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 ...
