  • UV LEDs making waves with clean water

    Oxford Instruments systems now facilitate water purification technology With World Earth Day last week I’ve decided to make this weeks blog about how new technology is being used to enhance people’s lives in a fundamental way. The UN recognises that clean drinking water is a global issue with over ...

  • A solution to fracturing water supply and disposal issues

    “Water, water, everywhere, Nor any drop to drink.” –The Rime of the Ancient Mariner, Samuel Taylor Coleridge Many topics of conversation among oil and gas industry professionals are predictable – oil price trends, the “great shift change” imperiling the available workforce, and production quotas and caps from OPEC. Yet one pressing topic among those developing ...

  • Contaminated Water

    Treatment of Contaminated Mine Water Discharge Recent estimates have suggested that in the UK 2,500 km of streams and an area of 9,000 km2 of groundwater bodies are at risk of failure of Water Framework Directive Objectives due to mine water pollution (Jarvis & Rees 2004). For over two decades the Loughor Estuary in South Wales, which carries SSSI status, had been ...

  • How to choose the best Industrial Water Filtration System for mining applications

    Over the course of the past few decades concern for the environment has brought about a large number of new regulations concerning the use of water in mining operations. These include how it is accessed, and how it is treated, using industrial water filtration to ensure all ...

  • Enhanced Bio-Remediation of Wastewater

    Bioremediation has been used to treat hydrocarbon contamination in municipal wastewater for centuries. Most microbes used in bioremediation today are naturally occurringyetspecifically chosen and cultured versus being genetically modified. Bioremediation rivals techniques such as pump and treat extraction systems, as it provide cost savings for municipalities, as well as environmental savings by ...

  • How Do You Choose the Best Reverse Osmosis and Nanofiltration Membrane System for an Industrial Facility?

    As global demands for clean water increase, more and more industrial facilities are looking toward membrane filtration solutions, such as reverse osmosis (RO) and nanofiltration (NF), to help manage intake, process, and waste water treatment. Using membrane filtration can help your facility reuse wastewater and virtually eliminate discharge fees, and depending on the industry or required use, it ...

  • Sterile wastewater treatment with vacuum distillation

    Hygiene requirements are growing increasingly strict in many sectors, and the treatment of industrial wastewater is no exception. The vacuum distillation process in particular has to deal with the question of sterile treatment and subsequent storage of water obtained from the process. The mere possibility of reintroducing wastewater into the production process makes it imperative to prevent ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • Tire Shredding: Alternatives to Landfills

    For many reasons, whole tires pose a major problem to landfills. The most obvious is the inefficient use of space. The actual rubber of a tire takes up only a small fraction of the space a tire occupies, and the rest of the space is wasted. A less obvious but far more serious problem is that tires may trap methane gasses when buried with other garbage in landfills. When this happens, the tires ...

  • Monitoring Metal Contamination in Water

    Metal contamination in drinking and source water has proven to have economic and health impacts on the human race. Regulatory agencies understand the importance of remediating metal contamination in our water supply to ensure safe consumption of drinking water. In order to properly remediate our water supplies, one must first determine cause of contamination and the source of the problem. ...

  • Secondary removal of chlorophenolic contaminants in water

    In this study, several factors important for the design of a water supply treatment system for the removal of trace amounts of organic contaminants by microorganisms in a fixed-film were assessed. This entailed evaluating the effect of seeding with adapted microorganisms on the acclimation time, determining what depth of support material was required for removal of contaminants and observing the ...

  • Water contamination in fuel: cause and effect

    Water exists in three physical states and depending on the surrounding conditions it finds its way to the fuel systems like the high pressure common rail (HPCR) fuel systems on diesel engines. The important point thereafter is to provide the best possible on-engine protection by securing the fuel injector systems from severe damage. As the environmental challenges and emission regulations become ...

  • Determining trace amounts of contaminants in water

    Introduction Pesticides, polychlorinated biphenyls (PCBs), and pharmaceuticals are a worldwide contamination problem. Several major US water bodies, such as the Hudson River, St. Lawrence River, Fox River and the Great Lakes have been contaminated with PCBs from industries discharging into these water bodies for decades. For example, from approximately 1947 to 1977, the General Electric ...

  • A Forensic Approach to Solve a Ground Water Contamination Problem

    In 2000, a subdivision outside a small city in southeast Texas discovered that the water supply wells that individual households had drilled were contaminated with trichloroethylene or TCE as it is commonly called. Since the extent of TCE contamination seemed to extend for over a mile in length, it was thought the “event” or “events” leading to the contamination had occurred some years ago. The ...

  • Impact of cleaning regimes on dental water unit contamination

    Microorganisms that have been identified in dental unit waterlines (DUWLs) are of concern because they can cause infections, especially in immunocompromised patients. This study aimed to assess the incidence of microbial contamination in DUWLs before and after intervention to reduce contamination, and to investigate the presence of coliforms, Escherichia coli and Pseudomonas ...

  • Treatment of contaminated water with pesticides via adsorption

    Static adsorption experiments of pesticides (alachlor, trifluralin and prometryn) on amberlite XAD-4 were carried out at pH 5. The effect of ionic strength (0.01–2 M) on the pesticides adsorption was also investigated. This effect is more pronounced for the adsorption of more polar molecules (alachlor and prometryn) compared to trifluralin adsorption. This phenomenon can be attributed to the ...

  • Waste water plant struggles with contamination case study

    A plant in the southwest US commissioning a wastewater plant utilizing proprietary technology for the removal of benzene, toluene, and xylene, or BTX, was experiencing challenges with throughput and elevated operational costs due to the presence of particulate contaminants. The plant takes the wastewater and processes it, removing the BTX prior to being fed to the conventional wastewater plant. ...
