  • TOC analyser improves lab efficiency

    Leading instrumentation company HACH LANGE is helping a number of key customers save valuable time and costs with its new IL550 TOC-TN analyser. TOC analysis is vitally important in applications ranging from power generation, wastewater, drinking water, surface water and ultrapure water, to agricultural soils, contaminated land and food. HACH LANGE analysers therefore offer a range of options ...


  • Comparison of the water purification efficiency of two different flocculation-sediment-filtration (FSF) processes in Chaohu Lake in China

    A novel biofilter (BF) with the potential to improve pollutant removal when used as a substitute for sand filters in water purification processes is presented. To investigate BF's pollutant removal performance, a flocculation-sediment-biofiltration (FSBF) process was compared with a flocculation-sediment-sand filtration (FSSF) process on a lab scale, with water collected from Chaohu Lake. The ...

  • A Case for Point-of-Use RO Ultrapure Water Systems

    ULTRAPURE WATER CRITERIA - AN OVERVIEW 'Pure water' is a relative term. Practically speaking, no water, naturally occurring or treated by man, consists solely of H2O molecules. Forever in pursuit of achieving equilibrium with its surroundings, water has unique characteristics that result in its ability to dissolve most matter. This property of water to dissolve and transport materials is ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Spiral-Wound Elements for Potable Water Treatment

    Introduction Any new technology must overcome perceptions of the marketplace, which are not accurate. As a technology moves into new areas of application, new misconceptions also arise. Crossflow membrane technology is no exception. The first man-made, pressure-driven 'crossflow' membranes were made in flat sheet form. This membrane had to be configured in a device, and was first made in ...


  • Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

    Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...

  • Ultra-Pure Proof with Mass Detection

    Before joining the newly formed Reach Separations in February 2012, I spent five years at AstraZeneca in analysis and purification (latterly as group lead in reversed phase and chiral purification). This experience gives me a good perspective of both the needs of “big pharma” and, more recently, the needs of a specialist separation solution provider. My ...

  • Transformer oil quality control

    It is impossible to ensure reliability and longevity of energy systems without controlling the quality of transformer oil. Recent experience shows that approximately 30% of transformer oil, filled in power transformers, has deteriorated to the point when it becomes a risk factor. This is caused both to natural degradation of oil in operation due to thermal oxidation aging, and contamination with ...

  • What are the best companies for Zero Liquid Discharge Equipment and Technology?

    With an increasing push for environmental protection, many industrial facilities and effluent regulators are making decisions that lessen their impact on the environment and human health. Changes and implementations are constantly being discussed and met both nationally and internationally to change the way industrial facilities discharge waste, and it is important to know which companies are the ...

  • Chemical Air Pollution in the Clinical Research Environment

    There has been a revolution in awareness of chemical air pollution in research laboratories. I could tell you several 'horror stories' of casual exposure to mercury vapour, benzene and chromic acid (the ultimate glassware cleaning agent) among innocent biomedical PhD students (including myself) in the 1970s. But researchers in hospitals, and other laboratories can never afford to be complacent ...

  • Microfiltration and Ultrafiltration Membrane Systems: Common Problems and How to Fix Them

    Microfiltration (MF) and Ultrafiltration (UF) are membrane-based filtering technologies that use thin layers of semipermeable material to separate out contaminating particles, such as organic material, bacteria, suspended solids, and other pollutants. In industries such and dairy, pharmaceutical, and chemical, the separated material may be a product they are recovering, and more facilities ...

  • Belgian egg processing

    Between 3 and 4 million eggs are broken daily, 5 days a week, to produce egg-white, egg-yolk, and some mixed egg products for a total of 900 - 1000 tons of end-products per week. All is done under the highest hygienic standards. The wastewater treatment plant was built 10 years ago, when the egg breaking capacity was at 1.5 million eggs per day and was engineered for handling an expansion up to 3 ...

  • Activated Carbon Applications Excel at PCB Removal

    TIGG’s GAC adsorption equipment is used to remove PCBs from groundwater. For more than 50 years, polychlorinated biphenyls (PCBs) were commonly used in industrial materials including, caulking, cutting oils, inks, paints and as dielectric fluids in electrical equipment such as transformers and capacitors. Concerns over health effects led to a North American ban of ...
