Question on Sulfur Denitrator

[waltee1000]

For folks running sulfur denitrator is it normal for the effluent coming out of the reactor to be milky white? I have my reactor running for 3 weeks. Initially the nitrate went to zero at 1 drop per second so I doubled the drip rate. It's still adjusting to the change but water inside the reactor is turning milky white. ORP is -160 inside the reactor.
