Abstract
Aeration pipe for diffusion of a gas into a liquid medium, the pipe having a flexible microporous tubular wall of thermoset polymer particles and a thermoplastic binder for melt bonding said thermoset polymer particles and dispersing an antimicrobial compound substantially uniformly throughout the wall. The aeration pipe is useful in various environments such as aquaculture and waste water treatment.
Claims22
An apparatus comprising an aeration pipe for diffusion of a gas into a liquid medium, the pipe having a flexible microporous tubular wall of thermoset polymer particles and a thermoplastic binder for melt bonding said thermoset polymer particles and dispersing an antimicrobial compound substantially uniformly throughout the wall.
A method of manufacturing an aeration pipe for diffusion of a gas into a liquid medium, the method of comprising:
- providing thermoset polymer particles, a thermoplastic binder for melt bonding said thermoset polymer particles, and an antimicrobial compound;
- blending and extruding said thermoset polymer particles, said thermoplastic binder, and said antimicrobial compound to melt said binder and bind together said thermoset polymer particles and produce a gas diffusion pipe having a microporous wall with said antimicrobial compound substantially uniformly dispersed throughout said wall.
