Sustained supply of safe and potable water is of paramount significance in promotion of health and well being of the people. It is commonly observed that the mechanical components forming part of Flash Mixers, Flocculators and Clarifiers become soon non-functional. There are number of examples where these have served not more than 12 months from the plant commissioning. In view of this, the paper emphasizes the need to develop water treatment plant designs that minimizes the component of mechanical equipment as much as possible. This paper presents the designs of Floccu-Clarifier (FC) (Clariflocculator in established sense) based on Jet Flocculation Systems, which eliminate altogether the mechanical components in pretreatment of water prior to filtration.
