We are about to do some emergency repairs at our WWTP and we need to combine 2 900K digesters into 1. Or as close as possible anyways. About a month ago, I was able to decant the 2 basins to almost half and when we were just about to pump 1 into the other, we had another emergency come up and had to loan the 6" trash pump to the collections crew, and we never got them combined.
Anyways, within the next week or less (a few days if possible), I need to attempt to decant these two basins again and combine the remaining sludge into 1 basin.
We have very little chemicals to help this process... but we have a little bit of lime (several bags) and we have only a couple bags of Nalco polymer ( I think its 9908).
Does anybody have a suggestion on using either of these products to aid in faster decanting.
Oh, by the way, we have nocardia issues, so the settling in all of the basins is poor right now, thats why decanting the digester is difficult. Currently it takes 2-4 days of the aerators being off before we get several feet of water to begin decanting from.

Please help

Thank you kindly
