Flat, biodegradable carrier material for denitrificants in biological sewage plants

A flat biodegradable carrier material for biological sewage plants acts, in oxygen-poor waters, as source of carbon and hydrogen and is loaded with spontaneously growing denitrifier populations. The carrier material consists of a spunbonded fabric which is formed from at least 50% by weight poly- ep...

Beschreibung
Zusammenfassung:	A flat biodegradable carrier material for biological sewage plants acts, in oxygen-poor waters, as source of carbon and hydrogen and is loaded with spontaneously growing denitrifier populations. The carrier material consists of a spunbonded fabric which is formed from at least 50% by weight poly- epsilon -caprolactone continuous filaments. The other constituent of the blend is optionally another, biodegradable polyester.
