Firstly, it's a BAD idea to design a wastewater plant without an equalization basin, especially if you have peak flows up to 3 times the average flows!
Secondly, even if you were to design this w/o equalisation, depending in the expected flow profile (maybe the peak occurs only short while in a day), I would still size the aeration basin based on the average flow rather than the peak. I think if you do this, your -ve SRT should go away. However, it will be advisable to size the clarifier using peak flow.

thank u dear Idzham. so you recommend to design an equalization tank. can we utilize a first sedimentation clarifiers as an equalization unit? (if we design first clarifiers hydrolically for maximom flow). i think this idea can reduce costs.
