1. A method of treating wastewater comprising:
- a) providing a module having tows of fibers, the fibers each having an exterior surface exposed to the wastewater, a hollow interior, and a gas permeable wall between the interior and exterior surface;
b) providing at least one of hydrogen and methane gas to the hollow interiors of the fibers, the gas penetrating the walls for feeding biofilm on the exterior surface of fibers.

Abstract
A hollow gas transfer fibre is arranged in tows and potted into a module. The module may be used to treat wastewater by supplying hydrogen containing gas via the interior of the fibers to a biofilm present on an exterior surface of the fibers.

- 12. A method of controlling biomass population on fibres in a water treatment membrane reactor, the method comprising limiting the amount of food available for consumption by the biomass so that the growth of biomass is generally equal to or less than the decay of biomass when the biomass has a population sufficient to provide a relatively thin film of biomass on the fibres of the module.
