| Vertical reed bed filters and sand drying bed filters are
simple technologies which can be used to dewater septage. Reed
Bed Filters have a further advantage that they can stabilize
the solids into an odourless – pathogen free organic fertilizer
similar in quality to an organic compost. Sand Bed Filters have
the potential to stabilize septage solids to a quality similar
to a digested sewage biosolids that is suitable for land application.
Two pilot Reed Bed Filters and one pilot Sand Bed Filter are
being constructed and evaluated for a two year period at the
septage lagoon of Goulet Pumping in Green Valley, Ontario. Each
filter will receive between 1-2 loads of septage per week (12,000-24,000
L/week).
The primary objective of this project is to comparatively
evaluate the use of Reed Bed Fitlers and Sand Bed Filters
as solid-liquid separation technologies for hauled septage
under Ontario climatic conditions. A secondary objective is
to evaluate the role of Phragmites in the phytostabilization
of septage and in the maintenance of filter infiltration in
Reed Bed Filter, and the effectiveness of the Sand Bed Filter
to stabilize septage solids through storage, drying and sunlight.
