WWTP Klášterec nad Orlicí (CZ) – Pipe silencers DN150

At the beginning of the year we were approached by the operator of the WWTP, the company Vodovody a kanalizace Jablonné nad Orlicí a.s., for help in solving problems with excessive noise emitted by the air distribution piping.

The increased noise level, which reached up to 85 dB in the area of the WWTP, was repeatedly the subject of complaints from local residents, as the WWTP is located close to the housing estate.

The main cause of these high values was the inadequate damping of the pulsations in the discharge silencers of the blower units, which come from another manufacturer.

After examining the situation at the WWTP, we proposed the use of additional KUBÍČEK DN150 silencers, in all stainless version, each with an effective length of 1500 mm.

The design of these silencers is absorptive, where the internal composition of the silencing liner prevents degradation and “loss” of material, thus ensuring unlimited life and efficiency across the entire spectrum of blower regulation.

As a result, the noise level in the area in front of the WWTP was reduced by up to 45 dB!!!

The silencers were installed directly into the pipe line, as close to the blowers as possible. The connection was made by means of flexible compensators with metal casing.

The noise problem has been solved and we have another successful reference and satisfied customer behind us.
