BOD analysis (Read 393 times)

Jerome Le Cunff YaBB Newbies Offline I love Water and Wastewater.com Posts: 15 Gender: Company or Organization: Freelance	BOD analysis Nov 12^th, 2011, 2:06pm Hi, for my first question on this forum here I go: I did some BOD analysis of the inlet and outlet on the outlet analysis I got a strangely high value of 270 mg/l looking for day by day values I got 30 on the 2nd day and 200 on the 3rd day. For the other days I got normal increases of values. Does anyone know how could that happen?? Thanks

I get regular analysis on the inlet, the water that comes from the landfill and that strange behaviour for the analysis of the outlet water.

Is leachate suppose to be consistent? What has the BOD been since then.
