Project description


Advanced transport characteristics of RO and NF membranes by patterned selective layers

 

The successful candidate should have an interest in both practical experimentation in a laboratory and development of a theoretical model and its numerical simulation. The student will combine experimental data generated in the laboratory with mathematical predictions to explain new phenomenon observed. Laboratory methods will include development of new polymer membranes using ink-jet printing, or laser technology. Modeling will be based on the development and solution of Ordinary Differential Equations

Preferred background/experience: Chemical engineering, chemistry, mechanical engineering

This offer is open for MSc and PhD students. Positions available immediately at Zuckerberg Institute for Water Research, Ben Gurion University, Sede Boker Campus.

 

This project is funded by the Water Authority in Israel.

Electro/photocatalytic graphene derivative membranes

 

The successful candidate will study electo- and photo-catalytic membranes by development of polymer-graphene based materials. Degradation of pollutants in water, and fouling of the surfaces will be studied. This project is funded by the BSF.

This project is in collaboration with Prof. James Tour (Rice University, Houston, USA), and Prof. David Jassby (University of California-Riverside), therefore students will be expected to spend part of their research training in the USA. This offer is open for a PhD or Post-Doc.

Impact of aquifer water quality on bacterial concentrations, activity and diversity

 

Water quality in aquifer is often deteriorating due to constant drawing as well as percolation of different anthropogenic contaminates. The primary goal of the proposed study is to characterize the impact of water quality on aquifer microbiota. The insights from this project may provide new tools for aquifer reclamation and management.  Candidate prerequisite is a BSc in one of the following: Biology, Chemistry, Civil and environmental engineering or Soil and water. Preference will be given to candidates with molecular and field sampling experience.

The implication of rainfall-runoff-infiltration relations in southern Judea Mountain on groundwater

 

The proposed study aims at investigating the mechanism controlling the relations between rainfall, runoff, and deep infiltration in terraced in southern Judea Mountain. The study involves hydrological field measurements well as laboratory analysis. The proposed research is a collaborative of three research groups representing disciplines in hydrology: 1) Dr. Naama Avrahamov– a geochemist of groundwater from Judea R&D Center, (2) Prof. Ofer Dahan – a vadose zone hydrologist from the Department of Environmental Hydrology & Microbiology, ZIWR, and (3) Dr. Roey Egozi – a hydro-geomorphologist from the Soil Erosion Research Station. This offer is open for a MSc student.

The effect of nano and micro texture/roughness on ‘wetting’

 

Micro and nano texture/roughness can prevent water and oils from spreading on surfaces, i.e., can render surfaces omniphobic; however, there is no theoretical model that can quantitatively predict what kind of texture (shape, slope and size) is required to render surfaces omniphobic. Recently, we developed a theoretical model that addresses this challenge. The model defines the shape, the slopes and the size of the cavities/textures that yield omniphobic surfaces.

In this project we aim to test the theoretical model by (1) fabricating different micro and nano texture using ‘cleanroom’ facilities. Then, we will (2) measure the effect of these textures on the surface wettability, and (3) compare the results to the model predictions.

For this project we recruit M.Sc and PhD students, as well as post-docs. Suitable background would be chemical/material/mechanical engineering, physics or chemistry.

Impact of coastal feedwater characteristics on the performance of SWRO desalination facilities

 

The research will combine filed studies using a pilot system at IOLR (Haifa) and full scale testing at the Hadera desalination facility as well as controlled laboratory experiments at the ZIWR, Ben-Gurion University. The techniques used throughout the project will include molecular, biochemical and microscopical methods coupled to different engineered approaches. Scholarships are granted to the selected candidate. PhD/MSc Open Position.
