  • Biofilm control strategies in industrial processing waters

    Bacterial biofilms cause a number of serious problems for industrial fluid processing operations. Mechanical blockages, impedance of heat transfer processes and microbially induced corrosion result in billions of dollars of losses each year. In engineered systems, such as cooling water systems, food processing, and other industrial applications possible risk to public health and product spoilage ...

    Introduction The leak repair requirements, under Title VI Section 608 of the Clean Air Act Amendments of 1990, require that when an owner or operator of an appliance that normally contains a refrigerant charge of more than 50 pounds discovers that refrigerant is leaking at a rate that would exceed the applicable trigger rate during a 12-month period, the owner or operator must take corrective ...


  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...

  • Wastewater Mining and Reuse: Creating Benign Future Scenarios

    Wastewater mining: In addition to being perhaps the most uninviting combination of words, it sounds like a most unlikely idea. But for almost 30 years, Aqueonics, now headquartered in Greenville, SC, has pioneered such systems, starting in the ’80s, with its first wastewater mining project. For that project, Aqueonics provided an onsite or decentralized treatment system for a developer in ...

  • Do You Need a Raw Water Treatment System for Your Plant?

    Determining whether or not you need a raw water treatment system for your industrial facility can be a difficult decision. But if your plant draws from a raw water source (such as a river, lake, ocean, or groundwater), chances are you will need some sort of treatment. If left untreated, what is present in your water source can cause a variety of issues, such as contamination in drinking water ...

  • Compost in the mix for storm water management

    Bioretention areas, also known as rain gardens, are increasingly being used to capture and treat storm water runoff from impervious surfaces such as roofs, sidewalks and parking lots. These landscaped areas often feature native plants installed in an engineered soil mixture that includes compost. “Bioretention areas or rain gardens are an attractive storm water Best Management Practice (BMP) ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...
