Microscopic Particulate Analysis
Introduction In 1989 the EPA promulgated the Surface Water Treatment Rule (SWTR) in response to the 1986 Amendments to the Safe Drinking Water Act (SDWA). The overall goal of the SWTR is to protect consumers from pathogens. The SWTR recommends a multiple-barrier approach including source water protection, filtration and disinfection when surface water is used as source water for drinking. The ...

Element patterns for particulate matter in stormwater effluent
Particulate matter in stormwater deteriorates the quality of receiving water and sediment. Characterization of stormwater particulate matter by means of its particle-associated element pattern provides an aid to determining its impact on receiving surface waters. During a 6 month measurement campaign, we determined particle-associated concentrations of major pollutants and rare earths for three ...

LaserNet fines Q230 technology
The LNF Q230 offers a patent-pending, completely unique, coordinated analysis of particulate via imaging and magnetic sensing. This capability enables this device to do things that none before it have done. We can characterize BOTH the image of a 20-micron or larger particle AND determine if the particle is magnetic. We can bin the size and compare both the image-based and magnetic particle ...

Global solution: Gas and particulate analysis in Cement industry
Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

Physicochemical analysis of rainwater and suspended matter from Toluca city and Salazar, state of Mexico
Physicochemical analysis of rainwater collected from two sites in the State of Mexico, Toluca city and the Instituto Nacional de Investigaciones Nucleares (ININ) in Salazar, was carried out. The pH was measured twice at the sampling site and in the laboratory within five minutes following the sample opening. The SO42- was quantified by a turbidimetric method. The concentration of neutralising ...

Connecting Elemental Analysis to Particulate Count: A New Technique to Detect failures
Particle count and elemental identification answers two of the most important questions in oil analysis: "How many?" and "Where is it coming from?" These two measurements are the most critical in any machine condition monitoring application. Using current technologies, the particle count is often a pre-screen for conducting root cause analysis using SEM/ EDX. XRF and in some cases ferrography. ...

Fate of organic matter during moderate heat treatment of sludge: kinetics of biopolymer and hydrolytic activity release and impact on sludge reduction by anaerobic digestion
Temperature-phased anaerobic digestion with a 50–70 °C pre-treatment is widely proposed for sludge. Here, such a sludge pre-treatment (65 °C) was studied against the physical, enzymatic and biodegradation processes. The soluble and particulate fractions were analysed in terms of biochemical composition and hydrolytic enzymatic activities. Two kinetics of organic matter ...

Air Quality Monitoring
Why monitor air quality? Well, to monitor is to know. Everything else is just more or less qualified guesses. International, national and local air quality targets and limits are also tied to monitoring results. What is Air Quality? How is air quality characterised? It is quite common to find air quality indexes, where the ranges are divided in sections indicating “good”, ...

Time series analysis for the sulphur dioxide and particulate matter concentrations in the Aegean Region of Turkey
Air pollution has temporal and spatial variability. Time series analysis is commonly used to evolution of air pollutants in time. The sulphur dioxide (SO2) and particulate matter (PM10) concentrations in the cities of the Aegean Region for the period of 1990–2009 have been modelled by using autoregressive (AR) and autoregressive moving average (ARMA) models for the yearly, monthly, and winter ...

Characterisation for some emission sources in CMB calculation for Mae Moh area, Thailand
Particulate samples of agricultural waste burning, straw burning, forest leaf burning, heavy duty truck emission, paved road dust, soil, agricultural soil, coal, electrostatic precipitator ash, and emission from stack power plant were collected from the Mae Moh area. Chemical compositions of sampling filters were analysed to determine the particulate matter source profiles. The analysis included ...

Analysis of Trace Elements and Ions in Ambient Fine Particulate Matter at Three Elementary Schools in Ohio
ABSTRACT The results from a chemical characterization study of fine particulate matter (PM2.5) measured at three elementary schools in Central and Southeast Ohio is presented here. PM2.5 aerosol samples were collected from outdoor monitors and indoor samplers at each monitoring location during the period of February 1, 1999, through August 31, 2000. The locations included a rural elementary ...

Source apportionment of urban particulate matter using hourly resolved trace metals, organics, and inorganic aerosol components
Abstract Source apportionment analysis of hourly resolved particulate matter (PM) speciation data was performed using positive matrix factorization (PMF). The data were measured at an urban site in downtown Toronto, Canada during two campaign periods (April-July, 2013; November, 2013-February, 2014), and included trace metals, black carbon, and mass spectra for organic and inorganic species ...

Inside the Particulate Monitor – Filter Samplers
Some time ago, OPSIS published descriptions on how some well-established types of gas analysers work, namely those based on spectrometers, interferometers, and tuneable diode lasers. They all utilize absorption of light to determine the concentrations of gaseous pollutants such as nitrogen oxides (NOX), sulfur dioxide (SO2), hydrogen chloride (HCl), ammonia (NH3), and many more. The same ...
