Water added to maintain or dilute a water-
mud system. The added water may be
fresh water, seawater or
salt water, as appropriate for the mud.
Make-up water volume is an important
parameter in a
material balance check on solids content and solids removal efficiency for a mud system. The amount of
dilution strongly influences mud economics. If soft make-up water is needed, treatments to remove hardness ions should be done prior to adding the water to the mud to avoid
clay flocculation and
polymer precipitation.
