TITLE: PILOT WATER TREATMENT PLANT USING
CAPACITIVE DEIONIZATION WITH CARBON
AEROGEL ELECTRODES COMBINED
DE I- IPT. 12/05/95 WITH OZONE, CMWD PROJECT NO. 95-302 CITY MGlVd!d-
XOMMENDED ACTION:
lf the Board wishes to participate further in this project, the District staff will proceed with investigating the
development of a pilot water treatment plant in Carlsbad using capacitive deionization with carbon aerogel
electrodes combined with ozone or other treatment processes. Also, authorize staff to investigate and make
recommendations regarding a Memorandum of Understanding (MOU) for subsequent consideration by the
Board of Directors.
ITEM EXPLANATION:
Lawrence Livermore National Laboratory (LLNL) developed an experimental water desalination process using
capacitive deionization with carbon aerogel electrodes. The carbon aerogel electrodes can desalinate brackish
water with a relatively low energy requirement. A possible use of this technology is to desalinate sea water.
However, additional testing and development is needed to apply this technology for commercial and industrial
use. Attached are three pages summarizing the process operation and commercial status of the capacitive
deionization process. Other water treatment processes such as ozone and reverse osmosis can also be
combined with capacitive deionization to create a hybrid treatment system meeting requirements for ultrapure
water.
As a part of the alternative’water resources development program, the Carlsbad Municipal Water District staff
has been working with several parties interested in obtaining a license agreement with LLNL to construct a pilot
plant using the capacitive deionization process. One of the parties is Marleyozone located in Kansas who is
interested in combining ozone treatment with capacitive deionization. Other involved parties include
organizations interested in financing the pilot plant with rights to market its commercial use and companies
interested in incorporating other additional water treatment processes.
Discussions to date consider constructing, operating and preparing engineering reports on a pilot plant with
a budget of 33.5 million dollars. Of this amount, $2.5 million is allocated to LLNL who would build a 10,000
gpd capacitive deionization pilot plant, perform all testing, and produce a final engineering report detailing the
optimization needed for a full scale plant. From the remaining budget, $500,000 would be allocated to
Marleyozone for pretreatment and $500,000 to Carlsbad for plant siting, water supply, brine disposal, and
coordination activities. Financing for this pilot plant project remains to be determined, but will include private
financing and local, state, and federal grants and loans.
A Memorandum of Understanding is being prepared to outline the responsibilities of each party interested in
participating in the pilot plant project. The draft of the MOU is attached for reference. LLNL has issued a
“Letter of Intent” to participate in this project. (See attached.) The activities that staff at Carlsbad may be
involved with are also listed in the attachments. Proceeding further with this pilot plant in Carlsbad will require
significant staff time. However, the benefits could be the future construction of a full scale plant furnishing an
independent source of potable water and ultrapure water for Carlsbad.
FISCAL IMPACT:
The current costs for development of the MOU is within current fiscal year budgeting allocated for the Water
Resources Master Planning efforts. Although this action has little on no fiscal impact, subsequent action may
require the Council to make a determination on the level of fiscal involvement. For example, additional funding
from the City may be needed for development of a pilot plant project. The District participation or financial
contribution may be in kind or involve an appropriation.
Consideration will be given to the City’s role in this venture depending upon the financial commitment needed.
The City will not benefit by receiving any appreciable amount of water from this proposed pilot plant. However,
we will be participating in research to develop a cost effective method of desalting water for drinking purposes.

Additional details regarding financing of the project will be discussed during the development of the MOU.

The type of activities the City or CMWD could perform include:
l Siting the location of the pilot plant, coordinating the environmental process,
developing any mitigation measures, and handling conformance with land use,
zoning requirements and Coastal Commission, if required.
a Developing the system necessary to deliver the brackish water (i.e., less that 3,000
mg/L in TDS), and the system necessary to deliver seawater (i.e., 30,000 mg/L
and greater in TDS).
l Developing the system for brine disposal to the ocean.
l Obtaining electrical power, enclosures, and developing other site improvements
or appurtenances.
0 Coordinating the activities and requirements of the regulatory agencies to obtain
approval for potable use of the product water, and brine disposal.
0 Optimizing a large scale facility for Carlsbad and possibly adjacent communities
or the SDCWA.
0 Evaluating the pilot plant for commercial use in supplying water to Carlsbad.
l Arranging or coordinating lab testing of the feed water and product water possibly
using staff at the Encina Wastewater Agency or other certified labs.
0 Assisting in developing the protocol for field testing.
l Performing the construction or setup of the pilot plant facility including installing
manifold piping, pumps, valving, computer controls, schematics, promotional
material, trailer mounted control room, providing tours and making presentations,
and coordinating the research effort with other agencies such as the BUREC in
Yuma, Arizona.
0 Assisting in preparation of documents and reports for distribution in the industry
and regulatory use.
l Actively pursuing available funding sources in concert with the other parties. This
could include federal, state and local funding including programs from MWD and
the San Diego County Water Authority.
