This article looks at the different methods now available for analysing TOC.
  • Sludge can ooze money
    For municipal and industrial applications, sludge dewatering with belt filter presses and plate filter presses has proven to be an economical means of reducing sludge volumes produced from wastewater treatment plants. Depending on the volumes to be treated, payback periods on the capital cost of a dewatering plant can be as little as three months and rarely exceeds 16 months. John Koumoukelis reports:
