Preventive solution for odor pollution from WWP trickling plant

Dear All,
 

We are constructing wastewater treatment plant very close to the city centre.

Right now we are using wet scrubbers as they can handle higher flow rates and pollutant concentrations. 

The site is about 150-200 meters away from the existing local residents.

Can someone suggest better technology and options for odour pollution control?

We want to avoid the complaint from the residents.
 

Your opinion and recommendation are highly appreciated.
