Real-Time Ammonia Monitoring Articles

Why are we monitoring nutrients at different depths?

Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

Real-Time Control Optimizes Extended Aeration Processes

The population of Hillsborough County, Florida has doubled since the Valrico advanced wastewater treatment plant (AWTP) was built in 1990 to treat the sewage of several small communities west of the City of Tampa. When it began operation, the Valrico AWTP capacity was only 4 MGD; small when compared to Tampa's 96 MGD Howard F. Curren AWTP located not far to the east. But Valrico serves as a very ...

Real-time monitoring of membrane bioreactors with 2D-fluorescence data and statistically based models

The application of membrane bioreactors (MBR) for wastewater treatment is growing worldwide due to their compactness and high effluent quality. However, membrane fouling, mostly associated to biological products, can reduce MBR performance. Therefore, it is important to monitor MBRs as close to real-time as possible to accelerate control actions for maximal biological and membrane performance. ...

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 ...

Ammonia sanitization of blackwater for safe use as fertilizer

Source-separated blackwater from low-flush toilets contains plant-available nutrients and can be used as a fertilizer. The aim of the study was to evaluate the impact on pathogen inactivation when treating blackwater with urea and/or lime. Blackwater was spiked with Salmonella typhimurium, Escherichia coli O157, Enterococcus faecalis, and Ascaris ...

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 ...

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 ...

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 ...

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 ...

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 ...
