This document discusses silver ionization technology for water disinfection. It begins by explaining the need to disinfect drinking water to remove harmful microorganisms. It then describes how silver ionization works by producing silver ions that kill microbes. The document provides the history of silver as a disinfectant and discusses how silver ionization is more effective and safer than chlorination. It also addresses common concerns about silver before concluding by promoting the use of silver ionization technology in water projects.

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.

9. Electrode Assembly Electrode Chamber

10. INSTALLATION
The equipment is mounted on the wall of the pump room or any
suitable room near the pump. Two connections are taken at two
different points in the pumping main in such a way the existing valve
is in between them as shown in figure. By using suitable pipes the 1st
connection in the pumping main is connected to the inlet of the
equipment and the outlet of the equipment is connected to the 2nd
connection. The valve is throttled to that a portion of he water passes
through the equipment. If this is not possible in big schemes an
additional ½ HP pump must be used. Necessary bleeding is done to
remove any air pockets within the system.
Now the water passes from the main line to the equipment. Necessary
flow meter is fixed in this by-pass line to indicate the quantity of water
flowing through the equipment. This can be varied by adjusting the
ball valves at the inlet and outlet of the electrode chamber. The
quantity of water flowing through the equipment can be adjusted to 2-
10 lpm.

11. SCHEMATIC DIAGRAM

12. FUNCTIONING
We have to calculate the quantity of water flowing in the
main line either by knowing the rated discharge of the
pump or by fillings a known volume of tank.
This rate of flow is converted into M3/hr and this value is
set in the control panel of the equipment. Once this is
set we can get an assured dosage of silver ions in water
always.
Electrode Active: This LED will be ON when the
electrode is functioning properly.
Change Electrode : This LED is ON when the electrode is
nearing completion.
We have to order and keep stock of fresh electrodes.

13. Clean Electrode: This LED will be on when the
electrode needs cleaning.
Mode Selection : We have normal mode to
discharge 0.01 mg/lit dosage of
silver ions .
We have save mode to discharge
0.005 mg/lit dosage of silver
ions.

22. 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.,)

23. 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.

24. Limitations of Silver ions as disinfectants
Hardness:
When the hardness is high i.e., above 800mg/lit, it
may tend to scale up on the electrode surface or
inside the chamber and will hamper the
ionization process.
Chloride:
When the concentration of chloride is found to be
more than about 300mg/lit, it may form silver
chloride and precipitate. Hence the action of
silver ions are disturbed.

25. pH:
Ideal pH for Water disinfection is 5-9 . Anything
below and above this limit will slow down the
disinfection.
Temperature:
Our equipments are designed with Constant
current Technology, so our system will work
the same in all temperatures.

26. Turbidity:
Turbidity definitely decreases the efficiency when
it is more than 10 NTU. More the turbidity more
the contact time.
TDS:
The conductivity of water various with TDS, but as
our System is designed on constant current
technology, it will work the same in all TDS from
100 mg/lit to 2500 mg lit.
