desalination solutions are available right now!
recent Tsunami that hit Asia was devastating with so many fatalities
and millions of people severely affected. Its aftermath left thousands
homeless without food, shelter and potable water. This is of tremendous
concern to us all as is the many years it will take for the region
As we witnessed the tragedy unfold, it left us
It was inevitable that gastroenteritis and cholera outbreaks and
other water borne diseases would occur in those affected areas.
It is of grave concern that a similar scenario could befall other
areas in the near future. It is important to set in place steps
we can take and ways to prevent such a calamity..
As immediate emergency relief, both short and long
term, the Desalination process can be used to extract fresh water
from the sea, brackish and well water.
water is soft water. The water produced is approximately 200 milligrams
per litre TDS (Total Dissolved Solids). Therefore, it is much softer
compared with ground water that typically exceeds 500 TDS. Reverse
Osmosis desalinated water is the water supply used on Cruise Ships,
Naval and Cargo Vessels.
While the Desalination process produces clean potable water, it does not
mean it is void entirely of the essential minerals, as widely believed.
Essentials are retained while removing the Heavy Metals such as
Mercury and Lead, Salinity and Bacteria from the raw source of water.
Since nanotechnology is
employed in the new systems today, the machines are more energy
efficient and comparable to running a series of light bulbs to produce
large volumes of fresh water.
They are smaller in size like a room air-conditioning
unit, therefore transportable as required in cases of Emergency
Aid. The machines are robust and lightweight, using anti-corrosive
space age composite materials and designed to withstand the harsh
As the climate changes throughout the world,
such as the El Nino phenomena leading to drought, severe storms
and flooding, Desalinators are used as water makers in Hydro Alleviation
Programs worldwide in areas where fresh water is scarce. It is increasingly
important for major water supplies in countries like Trinidad, Spain,
Malta, United States of America, Cyprus, the Middle East and countries
in Asia and Africa.
Desalinated water has always been more expensive
than ground water. However, since 1990, the cost of producing drinking
quality water using Reverse Osmosis Technology has reduced significantly.
It now competes with traditional sources, which are becoming more
expensive due to environmental and location factors with the benefit
of being independent of rainfall.
We promote a Green and Environmentally Friendly
approach since fresh water is only extracted and the run-off can
be diverted to the source such as the sea. The run-off water will
effectively be no different from the naturally occurring sea water
in terms of its salinity. Greenhouse emissions are minimised by
employing nanotechnology whereby less energy is used, this can be
offset by planting more trees as a community initiative.
In Cebu Philippines, for example, the aquifers
have suffered abuse from over-extraction from deep wells as the
main source of fresh water. This can only worsen as the population
trends and demand from industry grows. This can be said of most
parts of the country and other rapidly expanding cities like it.
As a consequence, people many kilometres away from a city in areas
far inland face an environmental disaster of sea water intrusion
We should embrace an Environmentally Friendly approach
for sustainable water in adopting a ‘security through diversity’
strategy through: Desalination, Catchment Management, Demand Management,
Recycling, as well as using the existing ground water and surface
water, whilst continuing trade with Irrigators. In doing so, we
minimise impact on the sensitive native flora and fauna.
What we have seen unfold recently is unfortunate. The survivors
are left with substandard conditions which will lead to water-borne
diseases. I firmly believe 'prevention is better than cure'. We
must be aware that fresh water is not a luxury but a necessity.
lot can still be done by embracing better, cost effective technology.
