Hey Dahlia You just assume a number. The higher you choose the HRT, the better (of course choose a number within the suggested range). But also pay attention that the higher the HRT, the higher the volume implying a higher capital cost. So one should do the balance between the plant's performance and the available budget.
Dear madam, if the tank septic tank capacity is 4000l and if it overflows once a week, how would you calculate the flow rate? is it equal to 4000l/7 days ? Thanks

This type of system should be standard when you consider the relatively short life of distribution/drain fields.
I totally agree
ABR highly lowers the TSS and FOG that could clog drain fields
Hello
Would you kindly provide the reference you used for the calculation, please?
Hello, how HRT is obtained? and is the 24 to 48 h an average for which type of wastewater? Thank you
