Principles of Water Treatment

  • ID: 2209243
  • December 2012
  • 672 Pages
  • John Wiley and Sons Ltd

Principles of Water Treatment has been developed from the best selling reference work Water Treatment, 3rd edition by the same author team. It maintains the same quality writing, illustrations, and worked examples as the larger book, but in a smaller format which focuses on the treatment processes and not on the design of the facilities.
