Dear Colleagues.
I am currently trying to create basic calculations for MBBR technology for domestic water. The technological scheme I have chosen is:
1. mechanical treatment
2.Anoxic tank
3.Aeration tank (MBBR)
4.Secondary settlement tank with lamellas.
5.desinfection
SALR - 95%
I think to use recirculating nitrate flow from aeration tank and recirculation of activated sludge from secondary settlement.
In these technological scheme will there be a change in the size of bio media ? what media surface area (m2 / m2) to use ?
Thank you in advance
Best regards
