Remineralized Potable Water Turbidity Control

Published on by in Case Studies

For desalination plant the use of lime or calcite along with carbon dioxide is inevitable.  This comes with a potential risk of control the turbidity spike at the outlet of lime treatment point.  

My question to all is, what should be limiting turbidity in finished water product using only lime or calcite application?  What I understand is during slaking Ca(OH)2 thus generated is the entity which creates the turbidity spike. 

Can we achieve turbidity less than 0.5 NTU and at the same time reach our minimum Ca2+ target in potable water?

What is the consequence of supplying 1 NTU to 5 NTU finished potable water in the distribution system, both for human beings and the safety of pipe network?

Your help much appreciated!
