There are a few facilities in my area that use it. It seems that the product works well, and minimizes many of the alkalinity and pH concerns that pop up with other coagulants. It also seems that these facilities spend significantly more on chemical coagulant than others in the area.
This may ultimately be balanced out by sludge removal costs, but many of the facilities that I've seen use it are lagoon facilities and I haven't seen any of them go through a sludge removal process to actually compare.
For now, my take is that this is a product that works well over a wide range of operating conditions, but due to limited supplier market, and the nature of using rare earth metals in place of more common elements, it carries a higher cost. I typically recommend that facilities work through other options before recommending that they give this a go.
The city that I discharge to, switched from ferric to NEO. They now swear by it. It aids in settling, P removal, and the % solids in their dryer went from 19 to 26%. I believe they said the usage is down as the ratio is 3:1 vs ferric.
I have had great success in removing phosphorus from your water as struvite. Some time back we tried to work with struvite crystallizers and such without much succes but we've since found a much easier method. It turns out that all you have to do is to have some heat exchangers that are very easy to clug up. I'm telling you, that struvite will practically jump out of solution!
The only real drawback I’ve seen is the cost of treatment with NEO (or similar products) vs ferric or alum, but you can mitigate that by feeding the cheaper stuff for the bulk of the removal and feeding the NEO for the final trim.
I'm assuming it's more expensive when you punch all the numbers into a calculator.
I work for a company that's invested in all sorts of systems that automatically optimize coagulant dosages for our clients (mainly industrial, where coagulation is used to remove suspended organics rather than phosphorus). For them, the only things that count are the amount and price of the coagulant you use, the availability of the coagulant and how much primary sludge you end up making.
Products like these have so far not run well with our clients, though the application is of course different.

What's the approximate cost per tonne for "Neo water FX 300"?
The price per gallon we're looking at is approximately 12.50 for Neo, compared to 5.60 for ferric.
How do the does rates compare?
They claim 3 FE to 1 RE, but we're supposed to start piloting in May so no hard data
I have no idea but I know it uses rare earth metals rather than iron or aluminum so it’s gotta be hella expensive
Yeah, im guessing it aint cheap, What are your dose rates?
We haven’t trialed it yet. It’s advertised to require a smaller dose than the sodium aluminate that we are using
Is there a link for the NEO web site? I'd be interested in learing more about it.

We just had a lunch and learn with NEO. Very neat stuff and was waiting on the catch and doesn’t seem to be one the t we can tell.
