1. MBBR:
The moving Bed Biofilm Reactor will be used for biodegradable COD
removal, nitrification and de-nitrification process.
Biological Treatment Unit
16
Saudi Aramco: Company General Use
Multiflo:
It will be used for phosphate removal were lime, coagulant and polymer are added to participate the phosphate as Ca3(PO4)2.
Biological Treatment Unit
17
Saudi Aramco: Company General Use
Actiflo Carb:
It will be used for solid separation and non biodegradable (refractory) COD removal where micro-sand, PAC, coagulant and polymer are added.
Biological Treatment Unit
18

Drum Filter:
It will be used for suspended solid polishing for
SUF protection.
Submerged Ultra
Filtration:
It will be used to extract and filter the clarified
water through the membranes which is used
For the TSS final removal.

Post Metal Removal
Two type of filter:
- First filter is removing Iron: Fe3+ is oxidized into Fe2O3.
- Second filter is removing Manganese: Mn2+ is oxidized into MnO2
