Sewer odours are unpleasant and affect well-being. Depending on concentration, they can even pose risk to health. Ventilating the sewer system can really put the brakes on this process while simultaneously reducing odour emissions. The COALSI system solution combines physical, chemical and biological methods. Only harmless and barely perceptible substances can pass through the filters.
Hybrid activated carbon filters to provide an effective odour barrier to organic compounds in all common sewer manholes. Available for street sewers and gullies.
