At present too much emphasis for emission control from vehicles and furnaces is placed on monitoring and cleaning the exhaust gases. This means dealing with large volumes of hot gases at low pressures. This may be unavoidable in the case of coal but the adoption of gaseous and liquid fuels allows a different approach. Gases and low boiling hydrocarbon liquids contain relatively simple sulphur compounds and may also contain mercury. This allows a fresh approach for emission control. Gases are...

Mercury has been elevated to the status of a pollutant of global concern owing to some of its unique toxic properties which pose environmental and health risks. A chemical element, mercury is found both naturally and as an introduced contaminant in the environment, mainly from high-temperature industrial processes such as alkali and metal processing, incineration of coal and oil in electric power stations, foundries, waste combustion and oil and gas processing. Mercury rapidly moved up the...

The EPA Issued the Mats rule ( Mercury Air Toxic Standard ) February 16, 2012 for all the coal & oil fired power plants in the USA and then the EPA issued the Portland Cement Mact on Feb 12, 2013 for the cement kilns operating in the US as well. When these rules were issued the US had almost 1,350 coal & oil fired units operating and a 100+ cement kilns running as well. So the plants had to make a choice as to which technology they were going to adapt for mercury monitoring compliance unde...

Gas chromatography/mass spectrometry is a workhorse for the analysis of semivolatile organic compounds in environmental samples. The Agilent Intuvo 9000 GC represents a significant advancement in gas chromatography and provides a number of advantages for semivolatile analysis. In this presentation, the performance of the Intuvo GC is demonstrated for the analysis of semivolatiles based upon the specifications of USEPA method 8270D. Included in this study is an evaluation of the Intuvo during...

Best Practices for Environmental Sample Preparation and Testing Abstract: Environmental laboratories adhere to strict procedures to ensure that they remain certified and that their test results meet regulatory standards. During this session, Matt Groff, a veteran representative to environmental labs from GE Life Sciences, will discuss ways in which environmental sample preparation and testing can be run more efficiency and accurately, while meeting all the necessary requirements.  With o...

In addition to being the largest water and wastewater utility in England with nearly 1,900 DMAs, Anglian Water's drive for innovation spurred an ambitious vision for leveraging Big Data to streamline operations to better service its 6.4M customers today and for future years to come. This vision dubbed the IRIS programme is a five-year project that came to fruition in 2015 with the completion of the cornerstone project, the replacement of one of the UK's oldest telemetry systems. This system c...

This work evaluates UV-Vis spectrometry as a tool to estimate nitrite in a continuously operated urine nitrification reactor. The need for such a tool originates from the sensitive urine nitrification systems which need control for stable operation. At this time, the LASSO model identification method which selects a small number of UV-vis absorbance wavelengths proves sufficient to capture the most important dynamics of the nitrite concentration. This is likely sufficient for stabilizing cont...

Emerging contaminants, such as pharmaceuticals, are a growing environmental concern.  These contaminants have been detected in environmental waters (such as surface water, ground and wastewater flows) at concentrations ranging from µg L-1 to ng L-1 level.  The majority are unregulated in the environment and as a result the risk assessment and ecotoxicological effect of the contaminants, their metabolites and/or transformation products are relatively unknown. To meet the prerequisite o...

Oxygen transfer in biological wastewater treatment represent the most energy demanding step of aerobic processes. Submerged aerators are designed to maximize the available surface for exchange by generating as fine bubbles as possible. Potential effects of process water characteristics on bubble sizes are too often not considered in wastewater treatment, while, liquid properties are known to have important effects on bubble size distribution (BSD) and transfer capabilities. The use of appropr...

Non-Revenue water is more a management issue than an infrastructure and Engineering challenge in Africa. Poor management and decision are the result of 65% of total non-revenue water. While the cost of reducing non-revenue water is very little compared to the economic and political cost of loss, very little has been done to address it. Nairobi City water and Sewerage company has in the last five years been proactive in managing the loss of water related to management and decision (Referred to...
