Volume 11, Issue 11
  • ISSN : 1021-2000



Attention is given in this review to water quality as it affects the unit operations of water purification. Physical criteria on which selection of unit operations may be based are put forward. The suggestion is made that the jar or similar tests be carried out by engineers to determine the nature of the orthokinetic flocculation to be applied. Some aspects of chemical dosing and dispersion are also dealt with.
