  • Top ten technologies for 2007

    Technology breakthroughs continue to come with what appears to an exponential rate. Some 30 years ago, recycling wastewater from a manufacturing operation and 'zero' discharge were no more than a dream. A fine filter was something that was used only in laboratories by qualified technicians. If you had organic emissions, they were burned in flares, not RTOs. We no longer have to use boilers and ...
