Noisy Sewage pump
A sewage plant contained a pump that was causing excessive levels of noise when used intermittently.
After examination of the project it was felt that the best solution was to reduce the noise as close as possible to the pump by using a sound reduction blanket of lead and acoustic foam with a fireproof cover. The air outlet of the pump could not be covered so it was also decided to use Noisekiller profiled acoustic foam on the walls close to the air outlet to absorb the airborne sounds.
The result achieved was to the satisfaction of the client and kept the noise levels under the government guidelines.
