Key Water Facts
Reed Bed sewage treatment system can successfully treat sewage to the required standards. It usually comprises of a settlement tank to remove gross solids, followed by either vertical or horizontal flow, specially prepared reed beds of specifically reared reeds. These selected reeds have the capability to transfer oxygen from the stems to the rhizomes (roots) where biological action purifies the ...
