Aqua Genesis Ltd completes designs and modifications
at SDSU Center for Advanced Water Technology.
The fifth
prototype HD desalination technology promises large volumes of water
avaiable in most world wide locations with access to salt or brine waters,
or
when used in conjunction with other filtration methods in water
reclamation.
New design
shows marked increase in potable water production from previous
models.
By enabling higher volumes, a given
desalination plant is now assured of higher flows to meet the needs of the
growing population in California.
The company is currently
examining options for a larger demonstraion plant in California for
desalination and possibly reclamation.
Reclamation use of this
device is specific to the final phases of reclamation where the highest
quality water is required.

Testing Information
Two parameters needed to be
tested for the proofs for with the Delta T: Volumetrics and
quality. The first prototype preliminary quality testing indicated
water at 3ppm, however, there were design problems and materials issues
with several engineers working on the project with conflicting ideas on
each. No company was formed and the group voluntarily
disassembled. Doug Firestone designed prototype 2 and together with
Ronald Newcomb, created the engineering drawings and formed Aqua Genesis
inviting a select group of engineers into the company. Firestone and
Newcomb built the stainless steel box that would contain the next four
prototypes and modifications (mods) of three prototypes. Prototype 2
was completed in May of 2004 and transported to SDSU late that month.
After several weeks of set-up initial tests were performed. Results in
early June were positive but data indicated certain changes would improve
results. Vapor tests indicated extremely high vapor pressure (half of the
equation) and results there were stunning considering the temperatures
used to create this pressure. Prototype 3 was designed and constructed
on-site at SDSU to test a condensation system design modification. Since
this was a system change this became a new prototype as opposed to a mod.
Tested indicated improved thermodynamics, but again indicated the need for
improvements according to the second law of thermodynamics and heat
conductivity issues. This suggested two possible solutions. Prototype
4 was a major change, a new condensation scheme was designed and tested in
prototype 4. The volume of product water came more in line with
expectations, however, there were flow problems relating to the prototype
that would not be true of operating units but, on consideration of real
world operational paradigms, this design was abandoned after thermographic
evidence indicated a gain of heat in areas that should have been cold.
Prototype 5 was developed. Testing was consistent with the needs of
the company for volumes and thermodynamic efficiencies relating to heat
conduction and emissivity. Volumes were stable and predictable and flows
were within expected ranges. Prototype 5 Modification 1 (P5M1) improved
the volumetrics. P5M2 was the final design that could be used to emulate
different configuration scenarios differently than earlier designs. Since
the company sells only water, and not the units, volumetric data is
pertinent only to the company and therefore was not observed by SDSU.
Test data found here is from this prototype. Click Here for Volumetric Data.Late in
October 2004 Professor
Eric Frost assigned a student observer to
represent the school to observe and verify the quality testing of the
water. Mike Higgins met us at the university then accompanied us as we
picked up water the night before the testing. We picked up 350 gallons of
sea water from Scripps Research Institute and filled the production water
sump with the water. The following day we ran the unit. Mike took samples
from the mid stream flows, capped them and placed them into the shipping
boxes for shipment to two certified labs. This is his confirmation letter. To see the testing protocols,
