DESIGN CRITERIA
(A) General Design Criteria for Small Water Systems
A designer of limestone contactor should be aware of the various
factors
affecting limestone dissolution before designing a
contactor to ensure its optimal performance. In summary, the factors
that can affect the dissolution of limestone include the quality
of water to be stabilized and the physical and chemical characteristics
of limestone to be used. Click here
