inhibitors and anti scale chemicals , formulation

I'd like to know more about some water treatment chemicals(mostly polyphosphates as anti scale and inhibitors) and I'll be glad if someone can help me.

   This book goes into decent detail but is still easy to understand about the chemistries available for cooling water treatment, and namely scale and corrosion inhibition.

   From what I understand, Poly-PO4 is more of a cathodic corrosion inhibitor than a scale inhibitor. Organic P such as phosphonates and polyacrylamide and polyacrylates are generally seen as better scale inhibitors.

2. You have to be more specific, but this article provides a good primer. https://view.imirus.com/515/document/13179/page/50

3. One of the significant drawbacks to any phosphates is that the P will, when it hits water, provide nutrients for algal blooms.  Current recommended nutrient levels for P are in the micrograms per liter.

4. Why don't you just use an inline cavitation device like ours with a coupke of catalyst that reduce scaling and stop adding chemicals.

5. H2SO4 is mostly used as anti scalant increasing solubility of colloidal molecules like silicates, specially for RO, later you have to neutralize its acidity with an alkaline reagent like NaOH

   1. are you sure H2SO4 is an antiscalant and it solubilize silicate?
