  • Reuse of California brine olive oil processing wastewater to meet zero discharge goal

    Abstract Reuse of low strength municipal wastewater is becoming quite common and many technologies are available for that purpose. However, treatment and reuse/recycling of high strength industrial wastewater is still a challenge. In this paper we present some case studies with implemented integrated systems to achieve zero discharge goal. We will concentrate on the description ...

  • Divestiture is nothing but a distraction

    Feel-good measures that have no effect on actual greenhouse-gas production are a diversion from the critical actions we must take before it is too late. As a college president and chemist, I have worked throughout my career in areas connected to climate change.

  • EPA studies identify techniques for critical leak testing prior to soil-vapor sampling

    Researchers at EPA’s National Risk Management Research Laboratory (NRMRL) in Ada, OK, are developing quality assurance (QA) measures for soil-gas and sub-slab sampling methods that help differentiate contaminant vapors due to vapor intrusion from background sources. Recent research focused on measures to identify leakage of ambient air into conventional vapor probes, which can significantly ...

  • Put energy into emission control projects

    Many companies feel pressured to spend the least amount possible to meet environmental regulations, primarily because compliance isn’t a profit generating endeavor. What some environmental and compliance managers fail to realize is that emission control equipment can quickly become a profit decreasing endeavor with this penny wise-pound foolish approach. With mandatory greenhouse gas (GHG) ...

  • 5 Tips for Handling Climate Skeptics in 2013

    While the New Year brings with it a sense of optimism, for those of us in the climate change business it means another year competing against any schnook with money and a billboard to address the American people (see the Heartland Institute). When it comes to the climate debate, ...

  • Degassing Refrigerators - Drill-head and Piercing-plier

    1. For what purpose do we have to degas a refrigerator? A refrigerator has to be disposed as hazardous waste. The refrigerants inside a hazardous refrigerator are harmful for the environment (ozone depleting and greenhouse effect). Most common refrigerants are; R12, R134a and R600a. The uncommon is the removal of NH3. Refrigerants are developed to dissolve very easily into ...

  • 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 ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...


  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • Green Green Grass

    A few years ago the North Sea managed a twelve month period without any major shipping disasters. Good news for the environment you’d have thought. However, in the same period up to one hundred thousand tonnes of oil were estimated to have been released into the sea. Some of this can be put down to natural occurrence, but by far the major part is dispersed from aircraft and shipping fleets ...
