The cyanide ions that cannot be “broken down” in the alkaline chlorination process are in very stable cyanide complexes, such as ferrocyanides or ferricyanides. These complexes are basically impossible to treat and are largely unaffected by traditional alkaline chlorination.

Accu-Labs has developed a cost effective process for treating complexed metal cyanides in your effluent efficiently. The Accu-Lab #707p EZ Treat process will precipitate the cyanide ion, and allow it to be removed in a subsequent clarification process. Results of EPA sampling of such a process showed that an average influent concentration of 2.7 mg/l CN was treated to less than 0.023 mg/l CN.

If you ever had trouble meeting your local POTW’s discharge limits for cyanide, contact Accu-Labs today to talk to one of our knowledgeable service representatives and discover how truly “EZ” it is to achieve total discharge compliance with the help of Accu-Labs #707p EZ Treat system!

WHY TAKE THE CHANCE?

Features and Benefits of Accu-Labs #707p EZ Treat Process:
* One-step process
* Saves time, chemicals, and money
* Precipitates complexed cyanides of nickel, iron, and zinc easily
* No Special Equipment required

PROVIDES TOTAL CYANIDE COMPLIANCE!

How to use # 707P EZ-Treat For removal of complexed cyanides:

1. Treat waste stream in normal manner to eliminate amenable cyanides.

2.Adjust pH to within 1.0 – 6.0.

3.Add the required amount of # 707P EZ-Treat:One quart will precipitate approximately 50 ppm of total cyanide in 100 gallons of effluent.

4.Add one pound of zinc sulfate for each quart of # 707P EZ-Treat used in Step 2.

5.Adjust pH to 7.5 – 9.0 for precipitation
