  • 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 ...

  • Abatement vs. treatment for efficient diffuse source water pollution management in terrestrial-marine systems

    Marine ecosystems are affected by water pollution originating from coastal catchments. The delivery of water pollutants can be reduced through water pollution abatement as well as water pollution treatment. Hence, sustainable economic development of coastal regions requires balancing of the marginal costs from water pollution abatement and/or treatment and the associated marginal benefits from ...

  • AFM water treatment for biodiversity

    The discharge of List 1 bio-accumulated chemicals into the marine environment is one of the most serious forms of pollution that we inflict on our environment. The marine enviroment is responsible for the production of most of our oxygen and reduction of carbon dioxide. Tropical rainforrests and terestial plants are also extremely important in dictating our local climate, however they ...

  • Contaminants of emerging concern in municipal wastewater effluents and marine receiving water

    The occurrence and concentrations of contaminants of emerging concern (CECs) were investigated in municipal effluents and in marine receiving water. Final effluent from four large publicly owned treatment works (POTWs) and seawater collected near the respective POTW outfall discharges and a reference station were collected quarterly over one year and analyzed for 56 CECs. Several CECs were ...

  • Bio-fouling control on marine vessels with ozone

    A recent pilot study on how to control accumulation of marine organisms on heat exchangers of marine vessels show that applying ozone is both effective and sustainable. Large economic impact Marine bio-fouling, or accumulation of marine organisms on heat-exchangers for cooling systems, is a challenge in the maritime sector and has both an economic and environmental impact. Worldwide ...

  • MIEX® DOC Process for Removal of Humics in Water Treatment

    INTRODUCTION Humic substances present a significant problem in water treatment by causing colour in water, increasing required coagulant doses, providing precursors for disinfection by-products and causing re-growth in the distribution network. Humic compounds comprise more than 60% of natural organic matter in source waters. Dissolved organic carbon (DOC) is a “bulk” measure of the organic ...

  • Transfer kinetics of perfluorooctane sulfonate (PFOS) from water and sediment to a marine benthic fish, the marbled flounder (Pseudopleuronectes yokohamae)

    We investigated the kinetics of transfer of perfluorooctane sulfonate (PFOS) from water, suspended sediment, and bottom sediment, to a marine benthic fish, the marbled flounder (Pseudopleuronectes yokohamae). Fish were exposed in three treatments to PFOS in combinations of these exposure media for 28 days, and then depurated for 84 days. A major part (37%–66%) of PFOS in the fish was in the ...

  • Water Treatment Plant: Benefits of Underwater Cameras

    Before fresh water can be made safe for human consumption it must go through a treatment process eliminating bacteria and any other elements deemed unsafe to drink. How does such a process occur and why is it relevant to us? We’ve written about the use of Deep Trekker remotely operated vehicles and pipe crawler systems in storm water systems, sanitation pipes, and water storage basins. A ...

  • Canarina DESCAR software · marine pollution modeling · algorithms 7

    The stratification phenomena is the existence of two homogeneous water layers and separated by a thin thermocline layer. In such a case, we can say that the water is stratified. There is no exchange of pollutants through this pycnocline layer. In case we suppose that a pycnocline layer exists, we will be able to check the stability by means of the application of the following equation: ...

  • Technical brief - containment for industrial services in marine, offshore & petrochemical sectors

    Conventional scaffold sheeting is an established method of providing temporary containment and weather protection for scaffold structures.  Material selection should reflect the application, the anticipated weather conditions and the expected duration of the project.  Furthermore, stringent Flame Retardant requirements for covering materials are specified on most projects. There are ...

  • Dewatering with Geotextile Bags - South Gippsland, Australia (Water Treatment) - Case Study

    A simple, cost effective new method of dewatering sludge is now available in Australia, writes Bill Kelly from CRS Industrial Water Treatment. The use of geotextilcs for containment and dewatering came about as a result of a major flood event in Holland in the 1950s. It prompted Dutch marine engineers to seek new methods and materials to build structures for coastal defences. The ...

  • Wastewater Treatment Works

    Margate and Broadstairs, two of the principal towns in northeastern Kent, attract thousands of visitors each summer to enjoy the beaches and countryside within easy reach of London. Such popularity comes with a cost. The infrastructure serving the area needs to be developed to keep pace with the rising population and the requirements of new UK and European Union legislation. With the ...

  • Scale-up of the MIEX® DOC Process for Full Scale Water Treatment Plants

    The MIEX® DOC Process is a new process developed by Orica Watercare, South Australian Water Corporation and the CSIRO for the removal of dissolved organic carbon (DOC) from drinking water. Results from scale up of the process to a 170m3/day pilot plant have been reported previously (Nguyen, 1997). The process has now been successfully scaled up and trialed on a 1000m3/day pilot plant located at ...

  • Taming taste and odor (T & O) problems in a water treatment plant

    Taming Taste & Odor (T&O) Problems Some taste and odors are caused by mineral constituents in the water, e.g. excess chlorine and hydrogen sulfide. However the majority of taste and odor are the result of biologic activity. Spring turnover of lakes and algal blooms are responsible for Blue-green algae (Cyanobacterium), Green algae and diatoms that introduce filter clogging organisms ...

  • Produced water treatment from a to Zinc - reducing levels of Zinc in a produced water stream

    Problem At vast depths, the ocean floor consists of layers of decaying plant and animal matter, containing chemicals like sulphate and zinc, which has built up over the years. When operators are drilling, the matter is disturbed and the various chemicals are released into the water. Since the mid 1980’s the pace of exploration, production, and development in the deep waters of the Gulf of Mexico ...

  • Marine Sciences Investigations in Support of Level Oftreatment Decisions for Municipal Wastewater Discharges in Puerto Rico

    ABSTRACT The Puerto Rico Aqueduct and Sewer Authority (PRASA) currently has National Pollutant Discharge Elimination System (NPDES) permits that incorporate relaxation (waiver) of BOD and TSS secondary treatment requirements for six of its regional wastewater treatment plants. The waivers are available under Section 301(h) of the Clean Water Act. Maintaining the waivers requires, in part, ...

  • Bayview Community - Wastewater Treatment System

    Formed just after the Civil War, “Bayview” is a 300 year‐old predominately African American community.

  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • Photo‐enhanced toxicity of fluoranthene to Gulf of Mexico marine organisms at different larval ages and ultraviolet light intensities

    Significant increases in toxicity have been observed as a result of PAH absorption of ultraviolet (UV) radiation in aquatic organisms. Early life stage aquatic organisms are predicted to be more susceptible to PAH photo‐enhanced toxicity as a result of their translucence and tendency to inhabit shallow littoral or surface waters. The objective of the present study was to evaluate the ...
