1. A process for monitoring a waste stream that has been treated for removal of metals comprising the steps of:
providing a supply of a treated waste stream, treatment consisting of metal removal steps: taking a first sample of the treated waste stream; taking a second sample of the treated waste stream; mixing the first sample with a chemical to precipitate metals, the mixing step including use of a static mixer; analyzing the mixed first sample in a turbidity meter to determine whether precipitated metals of present and mixed first sample; mixing the second sample in a static mixer with a precipitating solution to precipitate metal precipitating agents present in the second stream; analyzing the mixed second sample in a turbidity meter to determine whether metal precipitating agents are present in the mixed second sample; discharging the treated waste stream upon verification that the waste stream meets desired levels of both a metal content and a metal precipitating agent content.
