ACTIVITES
Research
Research is
concentrated in the following areas of water quality &
treatment:
Water
disinfection: The chemistry of disinfection in bromide
rich lake Kinneret water. Identification and kinetics the
formation of Disinfection By-Products in bromide rich water.
Utilization of
effluents for irrigation:
Disinfection of effluents prior to irrigation and the formation
of Disinfection By-Products. Fate of haloorganic compounds
present in irrigating water.
Bioremediation:
This study quantifies the factors affecting the behavior of
specific organic pollutants – chlorophenols, in the soil and
groundwater during bioremediation. This study also investigates
(i) the kinetics of the removal rates of chlorophenols in
contaminated sandy aquifers and (ii) the changes in the
hydraulic conductivity of the porous media caused by
accumulation and dynamics of biomass in the media.
On going researches
that are funded by the Grand Water Research Institute:
"Effect of
the biomass transport on the fate of hydrophobic- organic
-compounds in a porous media"
“ Long Term
Aspects Utilizing Treated Effluent (irrigation) in
Agriculture”
Teaching
The laboratory serves as a teaching place for
analytical methods to determine organic compounds with environmental
significance. Demonstrations of the instruments and of experiments
are held for undergraduate students. In addition graduate students
can receive practical experience and assistance in developing
methods for their research needs. Courses that held lessons in the
laboratory include environmental chemistry, water chemistry, air
quality laboratory and advanced analytical laboratory in
environmental monitoring.
Services
The laboratory houses the TOC and TOX instruments
that were purchased by the Grand Water Research Institute (WRI). Advice
regarding these measurements is granted and members of the WRI are
encouraged to utilize the instruments.
During its years of operation the laboratory
gained expertise in the analysis of organic contaminants.
Consultations and study-projects are performed in the following
subjects: organic carbon analyses (TOC), organic halogen analyses (TOX)
chemistry of disinfection and gas chromatography.
