Exceeding TKN limits

I'm working with a company that has continually had problems with TKN (total kjeldahl nitrogen) in there storm water. does any one know of methods or BMPs for reducing TKN in storm water

Hi, Beth. We don't really get involved in issues of this type unless it involves a metal finishing facility. But TKN indicates organic material which must be digested (with trickling filter, activated sludge, etc.). It would seem that if the storm water has too much TKN for discharge, you need to either do biological treatment (a huge job) or help this company stop allowing the stormwater to accumulate organics. What do they manufacture, and what can the storm water pick up?

I would start by looking for sources such as fertilizer or urea or?
I would be very interested in their collection site methods.
