Sedef,
You could have 2 questions to sort the out.
A waste water by ETP or WWTP
B removal of odor by ozone
For ETP or WWTP, you need to offer me the following?
1, inlet and outlet's BOD COD,TSS and PH,
2, water flow per day or hour,
3, to set up new ETP or upgrade original ETP?
4, site construction engineering drawing or how much land can you offer, like long, wide etc?
To remove odor is not compliacated, you only need to offer me space of your workshop.
Regards
Jesse
