Deodorization of Waste Water Treatment Plants is becoming an increasingly important need to avoid conflicts with the neighboring environment. The primary and secondary clarifiers, due to their dimensions and concentrations of stinging gases, are units that, so far, have been quite abandoned, concerning deodorization.
The traditional solution is based on total coverage and deodorization of the indoor faul air, with a number of air renovations per hour between 3 to 8, depending on designs. This solution is expensive, both in terms of investment and maintenance. In the present article an alternative is shown, covering exclusively the channels of the clarifiers and deodorizing them with small units of chemical adsorption, obtaining an efficiency of approximately 90% with respect to the open decanter.

Abstract
Deodorization of Waste Water Treatment Plants is becoming an increasingly important need to avoid conflicts with the neighboring environment. The primary and secondary clarifiers, due to their dimensions and concentrations of stinging gases, are units that, so far, have been quite abandoned, concerning deodorization. The traditional solution is based on total coverage and deodorization of the indoor faul air, with a number of air renovations per hour between 3 to 8, depending on designs. This solution is expensive, both in terms of investment and maintenance. In the present article an alternative is shown, covering exclusively the channels of the clarifiers and deodorizing them with small units of chemical adsorption, obtaining an efficiency of approximately 90% with respect to the open decanter. By adopting this solution instead of total coverage, savings of 90% on initial investment and 75% on energy and chemical adsorbent replacement are achieved.

Oczyszczalnie ścieków i przepompownie, są niejednokrotnie źródłem emisji zapachów i lotnych zanieczyszczeń, które mogą mieć wpływ zarówno na zdrowie pracowników jak i na stan urządzeń i percepcję, z jaką odnosi się ludność do tej działalności.
