  • 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 ...

  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • The rehabilitation of 43 year old waste lagoons

    In 1967 the City of Concordia, MO built a segmented lagoon system to handle the small town’s waste requirements. The main industry in Concordia is a Tyson renderings plant, and the lagoon system was designed to also handle that plant’s final waste and water polishing requirements. The lagoon system was a relatively standard design, consisting of an 18.7 acre primary lagoon, a 5.6 acre ...

  • UV Light Treatment for HVAC Systems

    Ultraviolet (UV) light can be applied to support numerous applications in a broad range of industries. In commercial paint spray booths and label manufacturing plants, UV lamps are used to streamline paint jobs and the printing of logos. Outside of such practices, the light source may also be utilized to eradicate harmful, disease-causing bacteria. Systems that rely on the light’s ability ...

  • 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 ...
