I agree with Dave gaybba, focusing on your point and non-point sources of pollution will help paint a better picture of the type of treatment design will be best for your wetland. CSO data if you have any (combined sewer overflows) or even watershed delineations would be a good start to analyze hydrology and rainwater runoff. You can also look into LID (low impact development) storm water practices to supplement the effectivemess of your wetland design.

Thank you for all comments. The project spesifically focuses on the treatment of only a portion of river water itself by a off-side  wetland treatment system. The river water quality is like: ammonium: 2,5 mg/L, Nitrate: 3,7 mg/L, Tot-P: 1,7 mg/L

Hi Dr Lufti, I would like to stay in contact and discuss this going forward. This is exactly my field and focus, we manage to reduce ammonia, Phosphates (P & PO4) and Nitrate by between 70 - 90% in Treated Sewer Effluent (TSE) or PO4 14mg/L to 1.5mg/L, P 5mg/L to 0.6mg/L and Ammonia 1,0mg/L to 0.1mg/L.  These are obviously out of 1 report in Dubai with Emaar and European Golf Design. We do the same treatments in Malaysia, Singapore, Pakistan, UK etc. By reducing this "Super Eutrophic" state, the DO systematically increase, allowing the river/water body to rehabilitate itself. Its more of a proactive than reactive approach with a total unique technology.

Regards

Dave
