TDS Removal in Stormwater Ponds
TDS Removal in Stormwater Ponds
(OP)
I'm in the process of designing/researching the removal of TDS from a stormwater pond at a mining facility. The facility that I'm working on is pumping mine water to a stormwater pond. TSS settles in the forebay, however, TDS (currently a stained, greenish tint in the water) is present in the forebay, the pond, and at the discharge. Google search, stormwater handbooks, referencing other facilities indicates there isn't much information available regarding the removal of TDS. From what I've found, it appears my options may be: 1. Flocculation/chemical additive. 2. Subsurface discharge. 3. Larger pond to promote percolation/evaporation.
Does anyone have any input or dealt with TDS?

This could lead you to use different options as a sediment pond (using law stokes and flow rate and some lengh to width ratio), flocculation (ouch!), infiltration (if possible), etc.

I saw a presentation from a guy who was using PAM on a lake down in Florida, and it worked too well. After a week the lake was so crystal clear everyone could see the old tires and whatnot on the bottom, so they had to dial it back a lot. I think they were injecting it. I've done the "hang a floc log at the inlet" trick in sediment ponds in GA before and it works great. Not particularly expensive either, particularly for a mining operation.

With some room, you could be able to remove most TDS with a sediment pond. You have to know what you're dealing with.
Water sample ?
