  • 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 ...

  • 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 ...

  • Produced water at UGS Dolni Dunajovice

    Water is the main contaminant of natural gas. Mostly, it is a natural element of a reservoir content. When dry gas is injected into a reservoir, it absorbs volume of water there. Together with water, it absorbs hydrocarbons, which can be natural elements of the reservoir or of artificial origin and contaminants which were injected in to the reservoir with natural gas. During a withdrawal, this ...

  • 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 ...

  • How is biodiesel produced?

    This article is the first in a series that will take a close look at alternative fuels production and source materials. Over the next several months, we will cover natural gas, propane, ethanol, hydrogen, and fuel cells. This month, we will focus on biodiesel. Methods for creating fuels from renewable biomass feedstocks have been used since the 1800s. Vegetable oils were used in diesel engines ...

  • Comparing Evaporative technologies for the Recycling of produced Water

    Both multi-stage and MVR evaporators are capable of producing distilled quality water from produced water.  Distilled water quality ranges from 100 to 500 ppm TDS depending upon the initial TDS of the produced water and the level of concentration of bottoms (waste) obtained. Typical systems are capable of attaining final concentrations ranging from 270,000 ppm to 350,000 ppm TDS.  The ...

  • 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 ...

  • Algae as biomarkers, bioaccumulators and toxin producers

    Uncontrolled accumulation of wastes in marine environments involves an increase in organic substances and/or nutrients, as well as toxicity. The consequences of this enrichment for the homeostasis of ecosystems are unpredictable. The best studied consequence of such enrichment is eutrophication (Conti, 1996). Natural or anthropogenic eutrophication is the enrichment of a water body in nutrients, ...

  • Applications Report Presented at the Produced Water Society Seminar 2013

    “Performance Testing of Micro Media and Conventional Filters operating on Heavy Oil Produced Water in the San Joaquin Valley (California)”,  an application note, was presented by Michael Dejak and Michael Sheedy at the 23rd Annual Produced Water Society Seminar taking place in Houston, TX, this past January. The Produced Water Society Seminar is held every year. Each seminar ...

  • In the World: Small Mexican village produces clean water with solar-powered system

    MIT-developed system runs autonomously, producing 1,000 liters per day. In a small village deep in the jungles of the Yucatan Peninsula — a day’s drive from any source of clean, drinkable water — researchers from MIT are testing a system that purifies water with the help of the sun. The relatively inexpensive system consists of several modest photovoltaic panels, a large ...

  • Removal of dissolved and dispersed hydrocarbons from oil and gas produced water with MPPE technology to reduce toxicity and allow water reuse

    Abstract Legislation worldwide and current technologies used in the treatment of offshore oil and gas/condensate produced water are mainly aimed at the removal of dispersed hydrocarbons (dispersed oil). From the beginning of this century, new insights in the North Sea area revealed that specific contaminants in produced water are toxic and their impact on the environment was assessed. This ...

  • Analysing four of the most contaminated foodstuffs

    Food adulteration has been around since the Victorian times when cheese was often coloured with lead salts, beer and milk were watered down and flour was bulked out with chalk dust or ground bones [1]. Governments apply stringent legislation and quality standards to food products but the practice of adulteration, driven by greed and profit, is still seen. ...

  • Evaluation of emerging waterborne contaminants in Ireland

    A group of potential emerging contaminants in two Irish drinking water supplies were investigated. The aim was to investigate the presence of emerging contaminants which are not currently routinely monitored or regulated as part of the European Communities Drinking Water Regulations SI 278 of 2007 but are known or anticipated to occur in drinking water supplies. A monthly sampling and analysis ...

  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

  • One of Europe’s most contaminated sites

    VSD Avenue, a joint venture partnership between VolkerStevin, DEC and Sita Remediation, started work at the beginning of September on the remediation of the former Avenue Coking Works in Chesterfield; one of the most heavily contaminated sites in Europe. Guy Pomphrey, chairman of VSD Avenue, explains The £82m contract, signed in July, was commissioned by the client and site owner the East ...

  • Water contamination problems solved at automobile air bag manufacturing plant

    The Facility Based in a Rocky Mountain state, this facility produces the sodium azide pellets contained inside the air bags for automobiles produced throughout the world. The Problem During the manufacturing of the air bag propellent, frequent equipment washdowns produce large volumes of wastewater that contain sodium azide and metal sulfide salts. Sodium ...

  • Combined effect of water contamination with cobalt and nickel on metabolism of albino (wistar) rats

    Cobalt and nickel are essential trace metals in the human diet. They are also major components of the alloys employed in the plate and screw used for connecting bones in orthopedic surgery and in the manufacture of artificial organs (Kocijan et al., 2004). Cobalt is used also as coloring agents for pottery, ceramics, and glass. However, excessive amounts of these transitional metal ions are ...
