DDD2000
Diffusion Driven Desalinization
(Worldwide Patent)
Introduction
The
DDD2000 Desalinization (Worldwide
Patent) system turns salt water
into fresh water using far less
energy than any competing method.
In island locations, shipboard,
and in coastal applications,
it can provide an unlimited
supply of pure water from any
saltwater source. Given the
preponderance of people living
near coastal areas worldwide,
this holds immense potential
for the creation of much-needed
fresh water for all purposes.
Operating costs for typical
desalinization plants range
from $3.00 per 1,000 gallons
(gal) for reverse osmosis to
over $9.00 per 1,000 gal for
thermal distillation (multi-stage
flash, multi-stage evaporation).
In comparison, the DDD2000 technology
offers the potential of producing
fresh water in the $.69 to $1.29
per 1,000 gallon range. Hot
waste water from power generation
stations can also be used to
achieve even greater efficiencies.
DDD2000
Applications
The
DDD2000 can be applied to a
wide variety of problems. It
can be a key component in sustaining
the world's supply of clean
water, particularly in areas
with ready access to salt water.
Aside from clean drinking water,
the DDD2000 can provide clean
water for irrigation, recovering
vast areas that currently do
not have access to sufficient
fresh water. Communities can
use desalinization as a profit
generator, while satisfying
public utility needs. Water
may also be bottled for distribution.
In the U.S. operating oil and
gas wells produce 3 to 10 million
gallons of brine each, which
can be cleaned by the DDD2000
to yield fresh water.
The
DDD2000 Advantage
Thermal
power plants that use coal or
natural gas demand immense amounts
of water, both for cooling and
for steam production. Power
plants use over 277 billion
gallons of water per day, with
78% of that amount used for
cooling alone (W. Michelletti,
International Water Conference
1999). In fact, according to
the U.S. Geological Survey (USGA)
the largest category of water
withdrawals for the year 2000
was thermoelectric power (48
percent of total withdrawals);
irrigation accounted for 34%
of the total withdrawals, with
the balance of use by municipal,
industrial, and livestock operations.
The
DDD2000 provides
a
two thirds cost reduction over
conventional methods. It does
this without energy waste created
by conventional methods. In
fact, the DDD2000 makes good
use of waste heat generated
by power plants, solving two
problems at once.
Humidification
Dehumidification (HDH) is a
relatively new desalination
technology which has been under
development over the last 20
years. The DDD2000 is an economically
feasible diffusion driven distillation
process that improves on the
progress made in HDH desalination
that is viable for large scale
fresh water production (over
1 million gallons per day).
