Abstract
Reuse of treated wastewater is a favorable direction for solving water shortage
problems and meeting environmental quality criteria. Domestic wastewater in
isolated communities in arid regions can be treated efficiently in a stabilization
pond systems. The effluent quality can be further improved when stored in a series
of stabilization reservoirs. There are a series of parameters, which characterize the
effluent quality for agricultural reuse. The conventional biological parameters
include fecal coliforms as a microbial indicator. The use of fecal colifonns does
not reflect the viral pollution of the effluent due to the poor correlation with virus
occurrence, Therefore, phages are proposed as enteric ~irus pollution indicators,
Phages exhibit similar behavior and survival in aquatic environment, and their
quantitative assessment is easy and a reliable enteric virus measure. Field results
from the treatment plant of the City of Arad (Israel) reveal the possibility of
characterizing the effluent quality in a stabilization pond and reservoir system.
The treatment plant includes a porous rock dike, resembling a horizontal trickling
filter.
