Water Quality (1 Viewer)

I was going throught the notes at http://hsc.csu.edu.au/chemistry/core/monitoring/chem945/945net.html#net4 and under the dot point "describe and assess the effectiveness of methods used to purify and sanitise mass water supplies" it says:
There are several methods used to purify mass water supplies. Most are variations on the following process:
flocculation and sedeimentation -> filtration -> sanitisation -> pH adjustment
but in the text book Macmillan Chemistry Pathways 2 its says the steps are aeration -> flocculation -> sedimentation -> filtration -> chlorination and microbiological tests -> flouridation
so wat im asking is which one is right, or are both of them right?

They are both right in the sense that there's more than one way to purify water supplies. But I would go with Thickett, he is more comprehensive and has pH adjustment in there too IIRC.

you suppose to describe and assess the effectiveness of methods (so there must be atleast two if not a few). i did a few and described and assess the effectiveness based on cost and quality...

you could also have a look at the sydney water website on this, as it has a simplified version of how they do it.
