ecycling and reuse of the nonconventional water resources
such as wastewater is a practical solution for solving water
shortages. However, the treatment level and the effluent
quality is still an open question. Due to the climates changes,
randomized precipitation and over pumping of groundwater
there are only small chances that scarcity issues will be solved.
Floods water scarcely fills the increasing gap between supply
and demand. The regions suffering from water shortage and
shortage in food production will probably continue to stay
under scarce conditions unless special and big measures will be
undertaken.
A promising solution is to desalinate low quality waters such
as sea water, saline groundwater and wastewater. The effect
of domestic wastewater after being treated by conventional
methods and subsequently by nanotechnology is a promising
solution. Although the main nanotechnology desalination
suffers from adverse phenomena such as high energy demand,
membranes fouling associated with decrease in flowrates and
disposal of the brine, is the promising solution for coming
century.
Field experiments were conducted in a typical arid zone
(precipitation around 150 mm/year). The experiments lasted
four years and different species of annual agricultural crops
were cultivated in 0.6 hectare plots. The field trial consisted of
6 different treatments where the yield was monitored every
growing season in each of them. Each effluent quality and the
operating parameters of the nanotechnology system such as
transmembrane pressure, retentate and recirculation flow-
rates including salinity effects on productivity of agricultural
crops were continuously monitored. Also were monitored
the operation membrane system. The effects of water quality,
expressed mainly by the Electrical Conductivity (EC) of the
effluent were monitored and considered. During the ongoing
experiment an economic analysis was conducted, examining
the effects of water and energy consumption on fouling and the
costs affecting the efficiency of the effluent application.
Speaker Biography
Gideon Oron has completed his
D.Sc. studies in the Technion - Israel Institute of
Technology in the area of Water Engineering. After a postdoc period in Ft. Collins (Co.,
USA) he joined Blaustein Institute for Desert Research (BIDR), Kiryat Sde-Boker as
researcher. His activity is mainly managed around efficient use of waters in dry regions.
His activity in the general area of water resources includes looking at the reuse of
wastewater, runoff water and related economic aspects.
