Mr. Ksu-Joe, thanks for your advice, it is a little better now with internal circulation.

As you noticed, the smell comes in the evenings, yesterday it was about 9ish PM for instance. There is another time - 3.30-4 AM too. I think it has something to do with the earth getting cooler so the direction of wind changes...
You know Ginger, I think it depends more on the cleaning stages insite the Plant then from the wind.

I recently read the article which describes the those stages. See below:

Plant/Process Description:
First stage is mechanical treatment which consists of seven screens followed by grit removal. Pre-aeration tanks and then the primary settling tanks. The effluent then passes through the aeration tanks where only BOD is removed. The ammonia is treated with biological filters followed by the tertiary settling tanks. After sand filters the effluent is chlorinated and supplied to the city for horticulture irrigation. The primary and the biological stage sludge is thickened with polymer and fed to the anaerobic digesters. The anaerobically digested sludge is dewatered with centrifuges and sent for thermal drying and windrow drying. The dried product is used for horticulture by the city and the general public.


So I guess depending on the cleaning procedures the smell type is changing as well as the strength of it.

I wrote an email to people in there yesterday to get the "smelly hours" .

I just wanna get an idea and then to find the solution...as I'm sick and tired it.

I'll check 7 days today and let you know.

Cheers
