Organic load is one of the most important parameters for discharge control of municipal and industrial wastewater. Permissible limits are guided through regulations and must be monitored accordingly. However, further opportunity to optimize plant performance exists by monitoring organic loading in upstream treatment processes. The use of on-line controls allows limit values to be adhered to, products to be saved, and plants to be protected against unforeseen events. Total Organic Carbon (T...

The quality of wastewater generated from industrial operations and municipalities is highly regulated and closely monitored. Traditional “oxygen demand” methods of determining wastewater quality can be time-consuming, costly, and less accurate. Total Organic Carbon (TOC) analysis offers a highly sensitive, non-specific measurement of organics present in a sample. Plants monitoring for TOC are better equipped to adjust their processes, protect capital equipment and meet effluent regulation...

The measurement of compounds in air using passive (diffusive) monitoring is widely recognized especially for long term (averaged) information on air quality.  The promulgation of EPA method 325 by the US Environmental Protection Agency (EPA) validates this sampling technique.  This method is currently used in the investigation of compounds in air at the fenceline of selected industrial locations.   During development, EPA Method 325 (passive sampling) has been field tested including int...

The Medium Combustion Plant Directive as presented at the AQE exhibition at Telford in 2018.

Presented at AQE 2018 Conference in Telford. Implementation of the Medium Combustion Plant Directive and Specified Generator regulations, the monitoring requirements and how they will be regulated.

Extraction of hydrocarbons within shale oil and gas formations present different technical and environmental challenges when compared to extraction from conventional hydrocarbons formations. The main concern is related to the use of hydraulic fracturing processes to break apart the rock and release the hydrocarbons. One of the primary environmental issues in relation to this process is the underground water supplies which can become contaminated by chemicals used in the fracking process as we...

Nitrogen and phosphorus are essential elements for humans as well as flora and fauna. In addition to their role as a nutrient their presence can also give important information about a sample e.g. the practice of over-fertilization or the likelihood of heavy metals being present in water bound to phosphate. Consequently, the determination of these elements is indispensable for the evaluation of water quality. The analysis of Total Nitrogen (TN) and Total Phosphorus (TP) to estimate such ri...

Presented at WWEM 2018. Nowadays, the tight environmental regulations demand a close control of the water quality in rivers, sea or even in waste waters. The water quality control require a regular monitoring due to continuous changes in several key parameters, such as seasonal water chemistry, overgrowing of plants, industrial waste and other factors. The chemical, physical and biological properties of the water define its quality. Currently, monitoring analytical parameters like the pH, te...

Increasingly stringent legislation in the European Union has driven down SO2 emissions on many processes from the 100's mg.m-3 to the 10's mg.m-3, or in some cases even lower. Consequently, the measurement challenge to accredited providers of compliance measurements and EN 14181 QAL2 calibrations has become increasingly difficult, and meeting legislative uncertainty requirements far from a trivial matter. We take stock of current capability for measuring this important pollutant and present s...

Regulatory update on the Industrial Emissions Directive, including the Best Available Techniques Reference document (BREF) for Large Combustion Plant, and also the requirements of the Medium Combustion Plant Directive.

Hydrogen Chloride and Hydrogen Fluoride are among the most important pollutants monitored from waste incineration plants, cement kilns and power plants co-incinerating waste. Due to the reactive nature of these gases and their low Emission Limit Value (ELV), measuring these gases with the required low level of uncertainty has been a challenge. New standards for instrumental methods of HCl measurement and manual determination of HF are due to be published by CEN TC264/WG3 in the near future. T...
