Didn't get a response on the post in the waste treatment/disposal forum. I am looking for some insight on the real drivers behind why an Engineer or Owner would utilize a scum concentrator as well as heating scum prior to disposal?

Is it strictly for larger plants and extreme cold weather climates? Does it have to do with the ultimate disposal: recycle to head of plant, send to digester, or dispose in a landfill with screenings/grit discharge? Are we trying to heat up the scum prior to entering an anaerobic digester to create less of a temperature shock, or are there other reasons?

Another way of asking is, what are the benefits of a scum concentrator and heating? Doesn't make a whole lot of sense to me considering the volume coming off primary and secondary clarifiers.....unless it was an unusually high volume entering a digester.

Thanks for any insight
