  • Rehabilitation of Hydrogen Grooving in Sulfuric Acid Line

    Around October 2001, one of the major petrochemical refineries located on the Texas Louisiana Gulf coast needed to rehabilitate 6' and 8” diameter “fresh acid” (98% sulfuric acid) lines. Such lines tend to suffer from internal gouging due to formation of hydrogen gas in voids, which are caused by turbulence at directional changes in the pipe flow such as elbows, etc. This is a natural event, ...

  • Restriction of gas losses in an overpressurised CO 2 reservoir using gel technology

    The overpressurised CO 2 field Bečej (Serbia) was explored in 1951. At the end of 1968, an uncontrolled gas blowout of Bč-5 well lasted 209 days resulting in 35 bars pressure drop in the reservoir until 2007. Hence, the substantial loss of reserve (> 17 billion m 3 ) became a critical issue of the operator. Environmental friendly chemicals should be used only for well rehabilitation. ...

  • Applications of Pipe Penetrating Radar for Advanced Pipe Condition Assessments: the Clark Regional Wastewater District (WA) Case Study

    Abstract Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids outside ...

  • Overcoming iron bacteria problems: An Australian perspective

    Iron bacteria are becoming an increasing problem in groundwater bores and are estimated to affect about 40% of the world’s water bores with anecdotal evidence indicating that this number is steadily increasing. Iron bacteria derive energy during their metabolism through oxidising soluble ferrous iron, present in the groundwater, to its insoluble ferric form. The resultant biofilm is ...

  • Working safely around hazardous materials and contaminants

    The first step in working safely around hazardous materials should always be a hazard assessment review. The OSHA standard mandates companies must conduct a hazard assessment to identify the appropriate personal protective equipment (PPE) and properly train employees on how to use it. OSHA compliance officers will review written hazard assessments for completeness and accuracy. In the case of ...

  • Maximize the coating life-cycle in severe wastewater environments

    In 2005, the American Society of Civil Engineers awarded a grade of D- to the nation’s wastewater systems based largely on the deterioration of sewage collection systems. That same year, the Bossier City Public Utilities Department in Louisiana restored a 5,000 square foot lift station using a 100 percent solids epoxy mortar system specifically designed to protect concrete in severe wastewater ...

  • Wastewater Treatment: Overview and Background

    SummaryWaste discharges from municipal sewage treatment plants are a significant source of water quality problems throughout the country. States report that municipal discharges are the main source of impairment to estuaries and coastal waters, the second leading source of impaired rivers and streams, and also are a major source of pollution in lakes. Pollutants associated with municipal ...

  • 5 Considerations for Choosing Pipe Bursting

    Homeowners who encounter sewer, drain, and water line problems often dread repairs not just because of the expense, but the major disruptions that they expect. Excavation, torn up lawns, and days of going without water are associated with traditional methods of repair. Fortunately, technology has made it possible to assess and fix pipes with minimal disruption by using a technique called pipe ...

  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...


  • UV set to dominate the municipal industry

    The use of Ultra Violet (UV) light has now become standard practice in most municipal waste water treatment processes. Effluent is now starting to be recognised as a valuable resource, not a problem that needs to be dumped.  Many waste water facilities are being renamed as water reclamation facilities, and whether the waste water is being discharged into a river, being used to irrigate ...

  • Cryotherapy is Cool

    Cryotherapy is a real facet of medical treatment that uses extremely low temperatures to help with pain and inflammation.  Not to be confused with cryopreservation, in cryotherapy the patients are only subjected to the cold for minutes. It seems like something futuristic, but it is actually an increasingly common treatment among athletes to replace ice baths and ice pack ...

  • The toxic legacy of Thailand’s ‘Great Flood’ will remain long after the waters have receded

    This year’s unusually long rainy season has left many part of Thailand, Lao and Cambodia inundated and resulted in the worst flooding crisis in Thailand for at least 50 years. The provinces of the central plains and many districts in the north, east and west of metropolitan Bangkok are now effectively under water. The huge volume of floodwater is such that flood levels are 3 metres deep in ...

  • Cyanide Spill at Baia Mare - Assessment Mission Report UNEP/OCHA

    Introduction On 30 January 2000, following a breach in the tailing dam of the Aurul SA Baia Mare Company, a major spill of cyanide-rich tailings waste was released into the river system near Baia Mare in north west Romania.
