Factors About The Cleaning Process For Raw Water

  • The necessary access port into the system is usually readily established by inserting a tee or a wye fitting, (a tee is preferable), into the system at a site convenient point where the cleaning is to begin or end.
  • Perhaps surprisingly, many raw water systems are cleaned in the reverse direction that their flow normally travels. This is done to accommodate site and system conditions and to minimize the disruption of flow in other connecting segments of the system.
  • The volume of mineral matter, adhering deposits, sand, construction oriented debris, (very common in old subaqueous installations for example), marine growth, bedding material, etc., that can be brought out during the cleaning procedure can exceed anyone's reasonable expectations.
  • In many operations, once the cleaning process has begun, high turbidity levels and the suspended solids incorporated in the flow usually precludes using this water in the normal treatment procedure. This temporary condition has been successfully resolved by varying customized applications.
  • Consideration must be given to the containment of the solids removed and the disposal of the water used during the cleaning process
