An improved apparatus and method for the delivery of various dispersants to a surrounding environment is disclosed. The apparatus comprises a composite membrane which is resistant to wetting by low surface tension dispersant emitting substances and provides an essentially uniform rate of release of dispersant into the environment. Previous problems of inconsistent dispersant release and apparatus leakage are avoided and a more durable, compact, and reliable dispersant delivery system is provided.
On décrit un appareil et un procédé améliorés pour diffuser différentes substances volatiles dans l'espace environnant. L'appareil comprend une membrane composite qui est résistante au mouillage par les substances à tension superficielle basse libérant les substances volitles et qui assure une diffusion de ces substances dans l'environnement à une vitesse sensiblement constante. On évite les problèmes antérieurs d'émission irrégulière de la substance diffusée et de fuites de l'appareil, et on assure une diffusion plus fiable et plus durable, avec un appareil plus compact.
