BOD/COD ratios (Read 217 times)

kelley71 YaBB Newbies Offline I love Water and Wastewater.com Posts: 2 Company or Organization: Southeastern Public Service	BOD/COD ratios Jun 13^th, 2012, 6:29am What inexpensive additives can used to either lower COD or raise BOD in leachate landfill water? Compliance in our area calls for a 6:1 ratio.

I can't believe that a regulating authority would allow you to raise the BOD level in your discharge to meet a COD/BOD ratio for very long! Is this wastewater discharged to a POTW? What are the other restrictions and limits to your discharge? Is there any treatment system currently for the leachate? You may have to chemically analyse the leachate to know the individual chemicals that make up the COD and BOD. However, if that is a hard and fast ratio; the glycerine from biodiesel production would be a cheap source of BOD (I can't believe that I'm even saying this). I think more information should be forthcoming.

We sample monthly and discharge about a million gallons a month. A little information I have found, references hydrogen peroxide and the possibility of using corn syrup. Any thoughts?
