Drying Out The Water Cycle

The global demand for goods is placing greater pressure on our available water reserves, with water scarcity an issue that an increasing number of regions already have to cope with. Coupled to this demand are projected climate changes to our rainfall, snowfall and temperature patterns.

Maintaining Integrity in Sample Preparation

Environmental samples comprise a wide range of matrices, each presenting the laboratory with analytical challenges. Analytical techniques and guidance documents exist to direct the laboratory to use the most appropriate sample preparation technique, but it is also crucial that the end user of the analytical data generated is aware of the preparation techniques which may be employed, and those that may be inappropriate for the sample matrix or test.

Waste Water Treatment

Biogas is once again a hot topic in Europe with an impressive range of projects deriving renewable energy from animal and farm wastes to MSW (Municipal Solid Waste) and industrial effluents1. The process of Anaerobic Digestion or Biogas technology as it is popularly referred to, has long been a treatment system of choice for industrial effluents and sewage even without the generation of excess biogas as valuable additional benefit. However, it is not only in Europe that biogas is making an impressive impact, but across Asia, novel large scale biogas plants are putting European systems in the shade.

Waste Water Treatment [Mar 2012]

To predict the efficiency of water treatment processes in the removal of protozoa cysts and oocysts, it is necessary to detect the parasites, measure their concentration in water and determine whether they have the capability of being infectious.

Wastewater Sample Stability

Analyte concentrations can change with time. Sample degradation through bacterial activity, volatility, chemical interactions and exposure to air or light can all cause changes to the composition of a sample. Consequently, establishing the length of time that an analyte remains stable, without statistically significant changes in concentration, is extremely important. It is essential to analyse the sample within the stability timeframe, or to highlight any samples that have deviated from this target.

A New Era for Sewage Sludge Management

The survival of civilisation is probably dependent on the outcome in the next 25 years of how humankind tackles the three challenges - namely energy supply, climate change and waste management.

Water - Our Vital Resource

Dr Graham Rideal, former Chairman and currently Science Correspondent for the Filtration Society, discusses our dependence on clean water, some of the steps we need to take to ensure its availability and the impact of new filtration techniques.

Environmental Laboratory Testing

The market for environmental testing laboratories has changed enormously over the last three years as a result of a seismic shift in the UK market and numerous changes in legislation. In order to survive, analytical companies have had to be adaptable, far-sighted and innovative in their provision of the comprehensive service that their clients require. The reduction in market size, particularly with respect to soil testing (as this is heavily dependent upon a thriving construction industry), has raised the level of competition in the market and laboratories need to focus on efficiency and excellent customer service.

Monitoring of Sea Water Desalination

Sodom and Gomorrah, lying in the desert heat, were the cities to which God sent Abraham in order to find righteous men in the heart of evil. It was where Lot and his family were living, and from whence they emerged into the world. The area has always been rich in drama and emotions. And, indeed, the project of bringing water from the Red Sea to the Dead Sea has always been controversial. On one hand, it may benefit the residents of the area and promote peace in the Middle East and around the world; on the other hand, the radical ecological upheaval may cause unpredictable and irrevocable damage.

Metal - Monitoring West African surface and ground water systems

This paper provides an initial assessment of metal concentrations in West African freshwater systems and proposes some preliminary environmental quality standards that could be used to assess impacts of development schemes in the region. In addition, some ideas to resolve the challenges encountered during the collection of samples are suggested.

Wastewater Analysis

Advancements in Wastewater Analysis: new EU directives and subsequent regulation on environmental protection continue to place technical demands on analytical laboratories.

Environmental Water Quality Testing

Water is critical to life, and water quality is critical to health. Not just human health, but all animals, plants and microbes - in fact, the whole global ecosystem. If water supplies, rivers and lakes become contaminated, then this impacts on the complete life cycle, often with devastating results, as demonstrated by the continuing health effects from the Bhopal incident 25 years ago, due to residual contamination in underground water sources. Less high profile, but more far reaching, is the issue of eutrophication of rivers or lakes - that’s the increase in nutrients due to agricultural run off. This is a common cause of algal blooms, leading to loss of oxygen, and the death of other species.

Analysis of Water Samples

As part of the procedures called for by the directive, a list of substances (priority substances) are specified and there is an essential requirement to perform large numbers of routine, trace determinations of these substances in surface water samples. Although some of the details of the WFD’s analytical requirement are still to be settled, it is clear that, as a result of this directive, water laboratories will have to analyse significantly more samples in the coming years.

Biological Treatment of Produced Water

Produced water, also known as drilling water, is waste water formed during the process of petroleum extraction from underground reservoirs. To better understand what produced water is, it is important to take a closer look at the actual oil drilling process. Drilling for oil, referred to in the industry as the ‘upstream mining process’ frequently involves pumping large quantities of high pressure, extremely hot water into the petroleum reservoir beneath the ground. The water pressure forces the petroleum upwards, and the heat of the forced water lowers the viscosity of the petroleum. The fluid that returns to the surface is known as produced water and is comprised of hot petroleum, water that was trapped underground, as well as the pumped water, along with earth and debris.

Premium Efficiency Wastewater Pumping - Optimising energy consumption and preventing blockages

There is no doubt that the pressures on a wastewater business have changed regardless of whether you are a publicly funded municipality, privately owned water company or a private operator of a wastewater collection system. We clearly see an increased focus on energy use with regard to cost and CO2 footprint, along with the demand to reduce the number of blockages and the associated risk of overflows.

Water Analysis

The potential risks to human health, wildlife and domesticated animals caused by the presence of chemical contaminants and pathogens in water is of significant concern to the Water Industry. Faecal pollution of water, resulting in waterborne diseases such as cholera and typhoid, has been linked to the deaths of millions of people around the world, although technological advances in water treatment have virtually eliminated these risks in developed countries. It is therefore, chemical contaminants that currently pose the highest risk to the safety of water supply, with surface waters and groundwater potentially containing thousands of these contaminants.

Groundwater Monitoring

Significant timesavings, improved sample process integrity, quality assurance and minimal quantities of potentially contaminated purge water to manage - are attractive as the focus on groundwater quality sharpens and economics demand best cost- benefit based methods.

Assessing, Sampling and Analysis Techniques

Do water samples collected routinely for monitoring programmes accurately reflect river phosphorus (P) and suspended solids (SS) concentrations? This paper examines several stages of standard sampling, preservation and analysis techniques (SSPAT) for water samples from two lowland UK rivers. Although universal analytical procedures are necessary for data comparison, this paper indicates that adopting a SSPAT approach alone may jeopardise sample representativeness. Therefore, preliminary surveys to assess whether SSPAT protocol is sufficient to quantify P and SS loads are highly recommended.

The Impact of Processes and Products

Over the past thirty years, the European Union has introduced a range of legislative measures aimed at improving the quality of the environment. More recently, EC Directives have particularly focussed on the discharge of contaminants into the aquatic environment. The implementation of these directives has delivered significant ecological benefits, but for these to be sustained, investigations into the impact of modern processes and products must continue. The laboratory plays a key role in better understanding these impacts and identifying compounds of detrimental effect to the environment.

Membrane Technologies and Resource Optimization

The role of water recycling and reuse is gaining immense importance. This is primarily due to the increasing disposal cost and the realisation that water is a valuable resource that must be used with great care. Fine chemicals, agro-chemicals and pharmaceutical industries have now products and processes which show a high degree of complexity resulting in effluents streams which are difficult to treat efficiently.

Approaches to Water Monitoring and Modelling

The population in certain areas of England has grown rapidly in the last few decades. As a result, additional water will be needed to meet predicted levels of customer demand in the next 10 years in several parts of the region. This expanding population is also creating a larger energy demand. It is inevitable that conflicts will arise between the pressure exerted on fluvial systems to meet these water and energy needs and more stringent environmental protection afforded by the Water Framework Directive (WFD) requirements (WFD UK TAG, 2007).

Source Tracing Techniques

The Environment Agency (EA) defines tracers as follows: “Tracers are substances which may be used to deduce the direction, destination and velocity of water or other substances”. Source tracing is a technique that uses tracers to track the movement of water to determine the relative contribution of various sources on its composition at specific points. For example, a tracer might be used to determine if faecal pollution from an effluent discharge pipe is passing out to sea or returning to the coast and thereby impacting water quality on the nearby beaches.

Controlling Parameters in Water Analysis

The COD (Chemical Oxygen Demand) is one of most important parameters in water analysis. In Germany as in nearly all European countries tax for indirect discharges is based on the COD. Using the oxygen consumption is reasonable in the case of tax because the delay time of waste water in a treatment plant depends mainly on its biological activity. The oxygen consumption again is a degree of biological activity. To determine the biological oxygen demand would be best suitable, but determination of this parameter is even more extensive compared to measurement of COD.

Water Quality Monitoring Below the Sea

Historically, water quality monitoring has relied on sampling or spot checking, however, the trend has been for process operators to move towards continuous monitoring. This, in turn, has created a need for sensors to be developed that are more robust and reliable and require less maintenance and ongoing calibration. At the same time, data collection and communication technologies have advanced considerably and it is now possible to view real- time water quality data at any time from anywhere. This article will outline some of the latest sensor technologies and examine the ways in which they are now able to resolve the problems traditionally associated with continuous monitoring.

Environmental Aspects of Concentrate Disposal

The amount of matter available on our planet is limited and final and has been so from the time of its formation (barring solar radiation and a few meteorites). Nature operates by the continual recycling of materials, including that of water. The water cycle is a slow one, taking thousands and even millions of years. In principle, each drop of clear water which we consume has passed through the whole cycle. The natural cycle involves three major energy consuming processes: evaporation with the aid of solar energy, evaporation with the aid of thermal energy and biological processes whereby membranes and biological pumps utilise chemical energy.

Environmental Laboratory Analysis

Remain up-to-date with changing legislation and technological advances. Recent technological advances within analytical instrumentation have meant significant enhancements can now be made in the methods of analysis within the Environmental testing market.

Where In the World Does Your Waste Go

Waste: the bottom line is that we produce too much of it. The reality is that millions of tonnes of it - from households, businesses and industry - still go straight to the bin and are, in turn, buried in landfill sites every year. And these sites are filling up; which is whythe EU has set a number of targets to ensure we look at other, more sustainable ways to manage our waste.
