It could be a number of things.
> Did you just start discharging to WWTP? Process may be adapting, but I agree with other responder that it may improve process (but, see below).

Mark:
As long as the water treatment residual (WTR) is formed at a near neutral pH, Al toxicity concerns are minimized - Al is the most abundant metal in soil to begin with!
WTR is great for controlling excessive soil phosphorus, which helps minimize impact of P pollution in waterways. As...
You betcha! I have worked for 13 years on their use to bind excessive soil phosphorus at laboratory and full scale - it works. I'm currently collaborating with a major US university on a AWWARF tailored collaboration project that specifically targets this option.
The key is thorough chemical...
