3. INTRODUCTION
Water -- a necessity for life, is a rare
commodity, which ought to be utilized
wisely and safely. We make great efforts in
providing drinking water to one and all in
our country. The government spends
crores and crores of rupees for providing
protected drinking water to every one in the
rural and urban areas.

4. THE NEED
WATER-tapped from rivers, ponds, wells and
bore wells may be contaminated and have
invisible micro-organisms like Coli-bacteria and E-
Coli bacteria, which cause the most of the
diseases in India. So just providing drinking
water by digging bore wells and fixing pump sets
and laying pipe lines don’t solve the whole
problem of providing safe and protected drinking
water. Atleast a small percentage of the total
outlay for providing drinking water has to be
spend for disinfection of water. All water borne
diseases can be totally controlled by properly
disinfecting the drinking water.

5. SILVER IONIZATION
Silver Ions Ag2+ are produced from pure Silver
Electrodes by passing a calculated amount of
current. This is produced according to the setup
in the control panel, which in turn is as per actual
flow.
Concentrated solution of Silver ions in water is
produced in the water chamber and is made to
mix with the flow of water in the pumping main
and then in turn we get the required
concentration.

6. HISTORY OF SILVER
The Egyptians kept their water in silver containers
to prevent contamination.
The ancient Greeks were the first to discover the
sanitizing power of copper.
The early American pioneers put silver coins in
large wooden water casks to provide them with
safe drinking water on their long voyage.

7. During the plague-ridden middle ages, mothers
knew that to place a silver spoon in an infant’s
mouth was a way of warding off disease.
Silver has been used as an Ayurvedic Medicine in
India for well over 2500 years.
It was NASA that harnessed what nature already
knew and designed an ionization system for their
Apollo flights.

8. HOW IT WORKS?
Silver ions produced in our system is positively charged
and most of the micro organisms are negatively charged.
There is an attraction among the silver ions and the micro
organisms. The silver ions disable the enzymes that micro
organisms depend on to breathe and thus kills them. Silver
is effective because of its capabilities of interfering with
DNA production and accelerating the death phase of
bacteria and viruses.
Because of the charge in the ions they repel each other and
are always in suspension. As their size is small they have
a large surface area of silver per unit volume of silver.
This small size with its large surface area to volume ratio
enables the surface chemistry of silver.

11. Characteristics of a good Disinfection Equipment
for Solar Pumps
 Has to work on Solar Power.
 As the Water quality is per IS 10500 standards,
there should be little residual disinfectant to
protect water from secondary contamination in
tanks or pipeline or at household pots etc.
 Disinfectant must not produce Disinfection by
products.
 The equipment should not require any salt or
chemicals for disinfection or regeneration.

12.  Operating cost must be nil for at least 5 years, when
operating for 4-5 hrs/ daily.
 There should not be any corrosion to the pumps or
pipes.
 No operator assistance must be required .Should
work only when pump operates.
 Should be trouble free i.e. No moving parts and no
corrosive parts.

13. Unique features of Senco disinfection
 Powered by Solar.
 Consumes current in mille amps only. (Negligible)
 Disinfection equipment is controlled by the level
controller.
 Disinfects all pathogens and produces water as per IS
10500 standards.

14.  No disinfection by products are formed.
 No salt or chemicals required.
 Electrodes can last for 3 years to 5 years.
 No operator assistance required.
 Good residual effect, hence protects water from
secondary contamination.

15. DOUBTS ABOUT SILVER
Our equipment discharges infinitesimal quantity of silver
ions,(0.01 mg/lit to 0.03 mg/lit) and not molecular silver.
World Health Organization (WHO) has suggested a
maximum limit of silver that may be consumed by a human
being is 10gms.
-Ref: “Guidelines for drinking water quality”
-2nd edition vol.l.P.No. :54 by WHO.
Permissible limit is 100 ppb (micro grams/lit for drinking
water as per EPA and 90 ppb(micro grams/lit) as per
European Union Standard.
(Contd.,)

16. In the whole life time of 70 years, considering one
consumes 2 lts/day for all 365 days, he consumes
only 0.5gms. this is 20 times well with in the
limits of WHO.
Retention rate of silver in human and laboratory
animals range between 0 and 10% as their ionic
size is so small.
