What do you do to remove the phosphate from the water to get rid of the eutrophication?

hmmm which dotpoint is that... i think you only need to know how to identify phosphates as opposed to removing it.

Rather... Go to 2005 hsc
question 26
describe two possible sources of contamination in this catchment and assess methods that could be used for purifying the water before it reaches the town.

flocullation and sedimentation are the only things i can think of to remove it. That's also part the answer in success one.

flocculation and sedimentation only takes out suspended particles.
I doubt that PO4 is a suspended particle as i think it would be separated throughout the water.
I have the success one book... thats why i posted the answer doesnt explain PO4

It will precipitate during flocculation as aluminium phosphate or calcium phosphate depending on the flocculant.
