Wastewater: big spike in Carbon Disulfide

February 15, 2021

Q. We had a huge spike in Carbon Disulfide in our waste water tank and can't discern where it came from. Huge as in 100X over the limit.

Do you know where and how this may have occurred?

A. Hi Amy. I'm not familiar with ceramics so can't comment on that potential source, but some silver plating brighteners contain carbon disulphide. Maybe if someone dumped a carboy of expired stuff you could get a huge amount in the wastewater? The wastewater treatment chemical DTC is made from carbon disulphide and perhaps that is what is showing up in the wastewater analysis depending on your analytic method?

Luck & Regards,
