1. MBBR:

The moving Bed Biofilm Reactor will be used for biodegradable COD

removal, nitrification and de-nitrification process.


16


Multiflo:

It will be used for phosphate removal were lime, coagulant and polymer are added to participate the phosphate as Ca3(PO4)2.


Actiflo CARB.mp4

17


Actiflo Carb:

It will be used for solid separation and non biodegradable (refractory) COD removal where micro-sand, PAC, coagulant and polymer are added.


Actiflo CARB.mp4

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.


Actiflo CARB.mp4

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
