 | Dr. Francesc Girlat visited UCLA, July 28, -
August 14, 2008 to conduct research on RO module hydrodynamics modeling and
development of soft sensors and performance models of RO plants.
|
| Dr. Francesc Giralt visited UCLA June 8-June
23, 2007 to conduct research on RO membrane rejection of organics, RO module
hydrodynamics and RO system control.
|
| Dr. Chen I-Ming of the Nanyang Technological
University of Singapore visited the UCLA WaTeR Center on March 2, 2007 to
discuss potential areas of collaboration in water desalination.

A delegation
from Nitto Denko visited UCLA on January 18 to explore technology areas of
mutual interest. Dr. Cohen gave a presentation focusing on the UCLA
Proposition 50 membrane desalination technology research project.
|
| Dr. Cohen visited the Weribee
Water Research Center (Victoria University) during the 2006 Fall/winter Quarters as
part of a collaborative research effort on high recovery brackish water
desalination.

| Jonathan Chow, a Ph.D.
student being advised by Prof. Felicity Roddick in the School of Civil &
Chemical Engineering at RMIT University in Melbourne, Australia, spent 4
weeks working with members Prof. Hoek’s research group in the Water Quality
Research Laboratory at UCLA (January-FEbruary, 2007). The short term objective of Chow’s visit to
UCLA was to further an ongoing collaboration between Roddick and Hoek
through implementation of a new analytical procedure at UCLA for
characterizing dissolved organic matter (DOM) in seawater. The analytical
procedure is already being employed by Roddick and Chow at RMIT to better
understand formation of disinfection byproducts (DBP) and removal of DBP
precursors via conventional treatment of colored groundwater. The long term
goal is to characterize how the nature and concentration of DOM change
during algal blooms of the coasts of Southern California and Southeastern
Australia. Increased biomass and DOM accompanies algal blooms associated
with stormwater runoff, pollutant discharges, and seasonal upwelling events.
The increased DOM can have catastrophic effects on reverse osmosis seawater
desalination plant operations.

| Professor Francesc Giralt
visited UCLA during November 2006. During his visit he worked with
Ph.D. student Eric Lyster and Professor Y. Cohen on a collaborative project
on RO membrane module performance modeling.
|
| During the 2005 Spring
Quarter, Ph.D. student Dan Libotean of the Universitat Rovira i Virgili (URV;
Tarragona, Catalunya) visited Professor Y. Cohen's PolySep laboratory to
work on the collabroative Ph.D. project between URV and the WaTeR Center:
"Forecasting Permeate Flux Decline in RO Plants" . Using
commercial RO plant data, Dan has developed a unique neural networks
modeling approach that enables forecasting of flux decline. Dr. Cohen
recently visited URV to work with Dan and his Advisors at URV (Professors
Dr. Jaume Giralt and Francesc Giralt). The above work was presented at
the 2006 Annual AIChE Meeting. This project will be completed in late
2007.
