  • Common Treatment Technologies for Inorganics in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate inorganics in ground water, surface water, and leachate. Treatability studies are usually necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would be particularly important to characterize the effects of adsorption and other processes of ...

  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...

  • Surfactant enhanced aquifer remediation (SEAR) using Ivey-sol surfactant technology

    This paper will focus on the application of Ivey-sol non-ionic surfactant technology to improve the in-situ remediation of petroleum hydrocarbon contamination is soil and bedrock aquifers. Normally hydrophobic organic chemicals (HOC) exhibit limited solubility in groundwater as the contaminants tend to partition onto the soil and bedrock matrix. This partitioning can account for as much as ...

  • Monitoring Phenol in Water

    The Situation A plant located in the eastern United States manufactures phenolic resin for applications in plastics molding. This plant uses well water for cooling its reaction process and then discharges the water into a local creek. A leak in the reactor and associated cooling equipment would cause phenol and phenolic compounds to contaminate the cooling water. Such a leak could ...

  • Biofilm Control for Industrial Waters

    Industrial operations can face a number of serious problems due to bacterial Biofilms growing in process water systems and cooling tower waters. Biofilm-induced corrosion, mechanical blockages and impedance of heat transfer processes result in huge monetary losses each year. In engineered systems, additional risks of biofilm-mediated contamination include negative public health consequences and ...

  • The fundamental conductivity and resistivity of water

    Pure water has a very low. but not quite zero, electrical conductivity. This conductivity provides a probe into fundamental properties of water, including the electrochemical mobility of the hydrogen and hydroxide ions. Deviation from this value is a measure of trace ionic impurities. Ultrapure water (UPW). with impurities at or below the sub-parts-per-billion range, is used extensively in many ...

  • Tracking biological pollution sources using PCR-DGGE technology at Ta-An Beach

    The environmental authority of Taiwan has announced that ocean quality standard A, with E. coli less than 1,000 CFU/100 mL is safe for swimming. Ta-An Beach in central Taiwan was found to have exceeded 1,000 CFU/100 mL, which is 51% of the total monitoring records. Sewage, piggery and duck wastewater are discharged directly into this area. The traditional pollution source trace methods did not ...

  • Log yard water treatment study

    Stormwater run-off from log yards and saw mills has long been a difficult waste stream to manage. The challenge arises from ability of wood and bark to easily leach high levels of organics (tannins, lignins, phenolics and resin acids) into mobile water. These organics can remain in the suspended state for months and exhibit toxicity to aquatic life as organisms break them down leading to a ...

  • Water – an essential sector in need of solutions

    The past year has seen water at the heart of global efforts to deal with some of the most pressing issues the world faces. The year started with the importance of water being underlined by the Global Economic Forum. In its latest report on global risks, water crises were identified as the number one risk out of 28 in terms of their potential impact following a survey of influential people around ...

  • Evaluation of chitosan as a natural coagulant for drinking water treatment

    Chitosan, a natural biopolymer, was evaluated for its ability to be used as a coagulant to treat water for potable use both in isolation and in combination with other water treatment technologies, specifically ion-exchange and activated carbon. Chitosan was found to be very effective for particle removal at doses far below those required for equivalent turbidity removal by inorganic coagulants. ...

  • Desalination and water recovery: control of membrane fouling

    Ultrafiltration (UF), Nanofiltration (NF) and Reverse Osmosis (RO) technologies are widely used for the production of safe drinking water, and for the recovery of reusable water from various industrial effluent streams. The most commonly encountered phenomenon in these processes, especially in water recovery application, is membrane fouling, and control of membrane fouling is regarded as a ...

  • HF Pure Water visits the Middle East

    HF Pure Water recently participated in the Water, Energy, Technology and Environment Exhibition held in Dubai, UAE. In speaking with numerous people that visited the HF Pure Water booth, it became apparent that there were limited opportunities for waste water treatment as many manufacturers simply dumped their wastewater into the ocean. This was confirmed in a meeting held with the Dubai ...
