Efficient Disposal of Concentrated Salt Solution (Waste Treatment)




We need information and advise on how to treat and dispose of approximately 5400 gallons of Brine Solution. The brine solution is from our waste treatment evaporation tank, and the chemicals in the brine solution are as follows: Sodium Chloride, Sodium sulphate, Sodium Nitrate, Potassium Chloride, Potassium sulphate, Potassium Nitrate, and trace amounts of metals (Cadmium, Zinc, Chromium, Nickel, Copper).

Some of the things that zealotry get done might have been better left undone. The case in point being that this saltwater probably belongs in the ocean, but ocean dumping is out of the question today; so you need to dismiss what might be the only good solution. This saltwater must be stored on dry land, patiently waiting, with eternity on its hands, for the day it will leach into the aquifer.

You need to contact a licensed hauler and have this stuff taken to a treatment and disposal facility where it will be encapsulated before disposal to slow down that leaching, to hold it within acceptable standards.

I don't know enough about your situation to make a definitive comment, but you may want to start thinking about a revamp to the way you handle wastewater, with an eye towards getting these salts back into the plating tanks wherever possible to minimize this problem in the future. You may have already done that though.
