  • Rolled Filters Move Filtration in a New Direction

    When selecting filtration technology, industrial users have long wrestled with the tradeoffs of dirt-holding capacity versus particle selectivity or quick-and-dirty change-outs versus process time. For many applications, a self-contained rolled filter offers an effective solution to both problems. Constructed with polypropylene hardware and various media in a spiral-wound design, rolled filters ...

  • A Path To Sustainable Infrastructure Solutions

    Today, for the most part, our communities’ infrastructure systems are developed and managed separately, by separate utilities and agencies. Sustainable infrastructure, on the other hand, blurs boundaries between our energy, transportation, water and waste systems to implement complementary strategies that benefit more than one system. Among our most important, and difficult, challenges will ...

  • What is Indoor Air Quality?

    Indoor Air Quality (IAQ) refers to the degree of air purity inside buildings that constitute the usual environment in which people carry out activities (offices, homes, schools, shopping and leisure centres, etc.) Because of increasing urbanisation and our contemporary lifestyle, most people spend a large proportion of their time in these closed environments. The high level of atmospheric ...

  • Using Biological Filtration to Remove Arsenic from Drinking Water

    In 2001, the U.S. Environmental Protection Agency changed the standards for arsenic levels in drinking water. At that time, the agency had estimated that more than 36 million Americans were drinking water that contained arsenic levels at or above 3 parts per billion. A new standard was set, lowering the maximum contaminant level to 10 parts per billion (ppb) from the previous standard of 50 ppb. ...

  • How to Choose the Right Commercial Air Filter

    When it comes to selecting a commercial air filter, or air filtration system, there are many variables that have to be considered. In general, the choice of which air filter can be made a bit easier by first defining the overall goal that you are trying to achieve which is usually one of two options. Is the purpose of the filter to protect the air circulation equipment, or is it to provide a ...
