Emergency WWT House Call
Plating Shop Shuts Down Due to High Metals
Robin was faced with the challenge of treating these high metal levels in the wastewater:
|Metal Level Prior To Treatment, Parts Per Million (ppm)||24.8ppm||23.2ppm||3.2ppm|
After completing jar testing and pH adjustment, Robin was able to determine the best way to treat the water. She switched their current coagulant to a coagulant that specializes in breaking the bond of heavy metals in water. Robin also added a metal precipitant to their process for additional help in breaking down the chelated water.
|Current WWT Product:||AquaPure SC Plus – liquid polymerized aluminum coagulant.|
|Robin’s Product Recommendations:||AquaPure I-300 – liquid coagulant that rapidly settles suspended solids & easily reduces chrome.AquaPure P601 – designed for use as a heavy metal precipitant.|
After the new process was in place, Robin trained the operator how to implement this process and jar test the wastewater.
Results of wastewater with AquaPure I-300 and AquaPure P601:
|Metal Level After Treatment, Parts Per Million (ppm)||0.02ppm||0.11ppm||0.04ppm|
Robin’s emergency “House Call” had the following results for our customer:
