It was a rather difficult decision for Amer Sweity to come from his hometown of
Amman, Jordan, to complete a master’s degree and then PhD at Ben-Gurion
University of the Negev. But now he is planning to bring the expertise he has
gained on Middle East water issues back to Jordan and other Arab countries in
the region at the conclusion of his studies.
“We are all suffering from
water issues – Israelis, Jordanians, Palestinians,” said Sweity, stressing the
idea that “nature knows no borders” and that water can be used to “bridge the
gap between Arabs and Israelis” in the future. “Besides developing the whole
region, you can promote peace in an indirect way. Water is a humanistic issue –
it’s not something you can keep and hide or avoid people from. It’s one of the
precious commodities that we have. You bring experts from this side to the other
side, and you create a method of communications between the people despite the
conflict going on.”

Sweity, a 30-year-old practicing Muslim, is BGU’s
first Jordanian PhD student, according to the university.
arrived in Israel in 2007 for a one-year program at the Arava Institute for
Environmental Studies, after having completed his bachelor’s degree at Hashemite
University in Zarqa, Jordan.
From there, he went on to earn his master’s
degree at the Zuckerberg Institute for Water Research, of the Jacob Blaustein
Institute for Desert Research on BGU’s Sde Boker campus, moving directly
afterward into the PhD program there. During his master’s degree, he developed a
membrane bioreactor for treating wastewater; his PhD focuses on the
desalinization of seawater and brackish water.
Sweity is working for his
PhD in the laboratory of Prof.
Moshe Herzberg, where he is researching
ways to “soften” salt water for more efficient passage through the desalinizing
membrane. They use a tool called an “antiscalant” to make the water softer,
because the so-called “hard” water – water with high mineral content – causes
salt residue to back up the membrane, reducing efficiency.
antiscalants often promote an attractive medium for microorganism growth, they
prompt the accumulation of unwanted “biofilm” on the membranes – which in turn
also clog the membrane and make it difficult for water to pass through, Sweity
So it’s his lab’s job to develop an antiscalant that won’t
cause so much biofilm development.
“We are trying to find the best
antiscalant we can use to make the water softer and also to decrease the growth
of biofilm on the membranes,” Sweity said.
Sweity is confident that as
far as water scarcity in the region goes, desalinization is the best solution
“Desalinization is the answer right now – the technology is
getting cheaper and cheaper,” he said, adding that by 2013 or 2014, Israel would
get 35 percent of its water through this process. “It decreases the pressure on
other resources – for example, the Kinneret. If they’re going to use it forever,
it isn’t enough.”
Sweity would like to use the knowledge that he gains in
his three more years at BGU to directly improve the processes of desalinization
throughout the Middle East.
“My dream is to work in the field of
desalinization, not to be stuck in an office,” Sweity said, noting that at the
moment he saw himself probably working in Saudi Arabia, Qatar or the United Arab
Emirates. “We [in Jordan] don’t have running desalinization facilities, but if
in future we have something, I would for sure be there.”
explained, doesn’t currently have the capacity to treat all of its wastewater,
and while a desalinization plant is in future plans, it has not yet been built.
The country is still collecting the majority of its water from aquifers and dams
and is not yet using the most up-to-date technologies, though “irrigation
systems and Israeli tech is being introduced,” he said.

be against making peace with Israel – after seeing many of his friends coming
here for research opportunities, he finally decided to do the same.
have suffered back home in Jordan because of the peace issues – I was against
being peaceful,” Sweity said.
“But I changed my mind because I wanted to
see who’s right and who’s wrong and decide for myself.”
He recalled that
“when I was doing my first degree back in Jordan, at that time, the second
intifada was at its beginnings. Every day there were people killing each other –
we were doing demonstrations in university.
I had a hard time dealing
with these issues. But after I finished university, some of my friends in Jordan
were studying in Israel at the Arava Institute of Environmental Studies. They
said, why don’t you come here?” And so he did – despite his family’s
disapproval, which, he said, decreased significantly once they saw how often he
was easily able to cross the border and come home to visit Amman.

he didn’t see staying here long-term as a realistic possibility.
not bad at all,” he said, but added, “I don’t see my future being here
forever. This is something temporary, but not forever.”
maintains that water is a great conduit for peace in the region.
together, creating this kind of atmosphere of a lovely environment – that can
put pressure on the politicians, and they can see that our scientists are
working together,” Sweity said.
“The problem in what’s happening right
now in the region is that there’s no trust at all between our leaders – but
between our scientists there is trust.”
