Rapid treatment of greywater (household sewage) by terrestrial weed Achyranthes aspera in SHEFROL® reactors

Abstract: In arguably the first‐ever study of its kind, a common terrestrial weed, Achyranthes aspera, has been used to treat greywater (domestic sewage) of wide‐ranging strength. The weed was used in the novel SHEFROL® (SHEet Flow ROot Level) bioreactor earlier developed by the authors, of which a patent claim has been registered. Without the use of soil or any other anchor, and at very brisk rate reflected in low hydraulic retention times of just 4–6 h, A. aspera was able to achieve substantial secondary treatment and… Show more

“…Flexibility in the choice of the main bioagents (the macrophytes). Not only freefloating aquatic plants, and the marsh plants like Marselia quadrifolia [41] which are anchored by their roots in nature, SHEFROL ® can accommodate even terrestrials like Alternanthera ficoidea, [39], Achyranthos aspera [40] and Catharanthus roseus [50]. This flexibility enables addition in SHEFROL ® channels of plants which show special ability in removing certain targeted constituents.…”

“…On the basis of a series of studies [36,[38][39][40][41][42][43][44], employing different species of macrophytes which, in their natural habitats, exist either as free floating weeds or marshy plants rooted in soil, or as terrestrial species, the efficacy of the SHEFROL ® technology has been demonstrated. It has been seen that besides very efficient secondary treatment, which its main role, SHEFROL, also accomplishes significant levels of primary and tertiary treatment.…”
