From February to July of this year, G+H Noise Control installed two sewage sludge dewatering centrifuges with acoustic hoods in a sewage treatment plant in North Rhine-Westphalia. In detail, the order comprised the manufacture, delivery and installation of two sound enclosures with a noise reduction of > 20 dB in the SONEX-SN system.
The order also included two sliding doors, two single-leaf access doors, LED lighting and ventilation. In addition, there was the requirement that all elements should be individually dismountable and remountable. To this end, G+H equipped all wall elements with 4 handles each and all roof elements with 4 attachment points each for easy dismantling and reassembly.
