The present invention relates to an ON LINE WATER PURIFICATION
SYSTEM, comprising of an Cylindrical Filtering Compartment with
an inlet for unfiltered water and an outlet for filtered water.
The Filtering Compartment has two filtration beds for carrying
out the process of filtration. The Filtering Compartment holds
a Spray Nozzle for aeration and removing iron; and a Micron
Filter for arresting bacteria.
The equipment also holds a PVC Funnel on the top where external
purifying chemicals can be poured for treating highly turbid
water.
The INLET of the equipment is to be connected to the Overhead
Tank and the OUTLET is to be connected to the water distributing
pipeline.
This 'ON LINE WATER PURIFICATION SYSTEM' is an unique invention
whereby the equipment purifies Overhead Tank water and enables
to distribute purified and filtered water through the water
distributing pipelines.
The already known water purifiers in the market can purify
only a limited quantity of water at a time. Most of the
existing purifiers can purify water from one single tap only.
As a result each room or more specifically each water tap
would be requiring one pufifier for itself.
The existing purifiers in the market can yeild purified
water at a very slow rate of time.
Our invention aims at providing a solution to the slow
purification methods existing in the market. It avoids the
complicated and expensive method of 'One purifier for one tap'.

The capacity of our invention the ON LINE WATER PURIFICATION
SYSTEM is 1000 litres per hour.
Our invention applies to an unique system of water purification.
In residential buildings, offices, hotels, restaurants etc.
water collected in overhead tanks is distributed through the
main distributing pipeline. This water collected in the tank
is prone to be contaminated. They collect impurities and are
seldom free from iron. Our invention is an 'ON LINE WATER
PURIFICATION SYSTEM'. Our invention relates to a system of
treating impure water of over-head tanks to be made iron-free,
bacteria-free and clean before its distribution to the different
pipelines of the water distribution system.
Accordingly this invention provides an ON LINE WATER PURIFICATION
SYSTEM comprising of a Cylindrical Filtering Compartment which
has a water inlet for unfiltered water and a water outlet for
filtered water.
The Filtering Compartment holds two filtration beds called the
ZEOFIL and ZEOFIL - A layer. The Filtering compartment also
holds a spray Nozzle for aeration and removing iron; and a
Micran Filter for arresting bacteria.
The equipment holds a PVC Funnel on the top where external
purifying chemicals can be poured for treating highly turbid
water.
The regulation of the water-flow through the inlet and the
outlet is done by means of Stop-Valves. The working of the PVC
Funnel and the Backwashing and Rinsing process is also regulated
by means of Stop-Valves.
The Filtering Compartment is covered on the top and bottom by
means of a set consisting of Rubber Bush, Rubber Cap and Brass
Clamps to hold the pressure of the water.

The entire equipment is fixed on a wooden stand and covered
from all sides by PVC, FRP, wooden or mild steel plates.
These plates are tightened to maintain hydraulic pressure.
This invention is an unique form of Purification System
whereby the inlet is connected to the overhead tank and
the outlet is connected to the water distributing pipeline.
Thus the equipment enables to purify overhead tank water and
to distributed clean, filtered water through the pipelines.

Functional Portion of the invention. It includes the following
successive elements s
1. Functional Inlet. (Marked X)
2. A Filtering Compartment (Marked I) holding two Filtration
beds (Marked G and H).
3. A Spray Nozzle (Marked O).
4. A Micron Filter (Marked J)
5. A combined set of Rubber Bush, Rubber Cap and Brass
Clamps (Marked E, C and F respectively).
6. A PVC Funnel (Marked M)
7. Functional Outlet. (Marked Y).

Diagram sheet No. 2 shows the Outwards Structional cage of the invention.
It includes the following elements t
1. Water Source Inlet (Marked W)
2. Stop valve Nos. F1, F2, F3, F4, F5 and F6.
3. Steel pipes connecting Stop-Valves and connecting stop-valves with the Inlet and Outlet.
4. Water Distributing Outlet. (Marked Z ).
The ON LINE WATER PURIFICATION SYSTEM has two sets of INLETS.
A water Source Inlet (in Diagram 2 marked W ) and a Functional
Inlet (in Diagram 1 marked X ). The two Inlets are connected
by means of steel pipes (marked P1 in Diagram 2).
The water Source Inlet can be connected to the outside Water-Source
Water from the Water Source i.e. Overhead tank enters the
equipment through the INLET w, passes through pipes P1 and
reaches INLET X .
From the Functional Inlet water passes through a narraw passage
flowing towards a Cylindrical Filtering Compartment (marked I
in Diagram No. 1). This Filtering Compartment holds two filtration
beds, A Spray Nozzle and a Micron Filter.
Water in the first instance has to pass through a SPRAY NOZZLE
(marked 0 in Diagram 1). This Nozzle is made of PVC. Water
entering through the inlet often contains dissolved air with it.
This dissolved air is aerated out by means of the Spray Nozzle.
The Nozzle also helps in changing the iron content of the water
by converting the ferrous into ferric form.
Passing through the Spray Nozzle Water falls into the Filtering
Compartment (marked I in Diagram 1). This Filtering
Compartment is Cylindrical in shape and made of PVC. This
Compartment holds two layers of Filtration media.
The first layer of filtration media is the ZEOFIL layer
(marked G in diagram 1). This bed comprises of Manganese
dioxide in granule form. Water falling on the surface of this
layer permeates through it; due to the oxidising effect of

this catalytic media any soluble or insoluble iron present in
the water precipitates on the bed.
After permeating through the first layer water reaches another
layer for the process of further filtration. This is the
ZEOFIL - A layer (marked H in diagram 1 ). This layer comprises
of Graded gravel and pharmaceutical grade Activated Carbon layer.
This layer arrests the bed-turbidities of the water as a result
of surface activity. It also removes any organic matter present
in the water, removes certain percentage of bacteria, removes
excess chlorine through dechlorination, removes Odour and makes
the water crystal clear.
After the filtration process in the two filtration layer beds
the water aquires a considerable amount of pressure.
The graded gravel of the ZEOFIL - A layer supports a 0.5 Micron
Filter (marked J in Diagram 1 ). Water under pressure passing
through this Micron Filter becomes free bacteria since this
Micron Filter arrests all bacteria of size not less than 0.2
micron.
Water filtered out of this Micron Filter finally comes out of the
Functional Outlet (marked y in Diagram 1). This outlet is
connected to the Water Distributing Outlet (marked Z in Diagram 2).
The two Outlets are interconnected by means of steel pipes
(marked P2 in Diagram 2).
The purified and filtered water coming out of Functional Outlet Y
passes through pipes P2 and flows out of the OUTLET Z. This
OUTLET 2. can be connected to the water distributing pipelines
for distributing clear, filtered water.
The PVC Filtering Compartment is covered by a Rubber Bush on
both the upper and lower ends (marked E in Diagram 1). This
Rubber Bush is covered by a Rubber Cap (marked C in Diagram 1).
This Cap is tightened by means of Brass Clamps (marked F in
Diagram 1). The combined set of the Rubber Bush, Rubber Cap
and Brass Clamps enable to hold the pressure of the water
upto 4 kgs/cm2. No welding or bolting system is done.

The invention includes another special feature :
It has the arrangement of purifying highly turbid water.
On the top portion of the Filtering Compartment is a PVC Funnel
(marked M in Diagram 1). This Funnel is connected to the narrow
passage of the inlet. This Funnel is regulated by a Stop-Valve
(marked F6 in Diagram 2).
At times when water entering the equipment is highly turbid
purifying materials/chemicals like liquid chlorine, fine alum
powder or Soda dust can be poured into the Funnel. On opening the
Stop Valve this external purifying chemical poured into the Funnel
seeps through the stop-valve-opening and enters the equipment.
The highly turbid water and the external purifying chemical both
falls in the Filtering Compartment and mixes with each other.
This mixing forms coagulation first and then floculation of the
highly turbid water. The water then settles on the filtration
beds. Then it passes through the ZEOFIL and ZEOFIL - A layer
and the previously mentioned filtration process is carried on.
Hence during the time of purifying highly turbid water this PVC
Funnel can be made use of. In other times i.e. for purifying
ordinary water the Valve F6 must be kept closed.
The water purification equipment described herinabove is fixed
on a wooden stand (marked D in Diagram 1) which is covered
from all sides by PVC and FRP sheets (marked B in Diagram 1).
The top and bottom portion is covered by wooden or mild steel
plates (marked A and K in Diagram 1). These plates tightened
on the top and bottom enables to maintain hydraulic pressure
up to 6 kgs/cm .
The regulation of the working of the 'ON LINE WATER PURIFICATION
SYSTEM' is done by a number of Stop-Valves. Diagram Sheet No.
depicts the position of stop valve Nos. F1, F2, F3 , F4,
F5 and F6.

During the time of working of the equipment (i.e. when water
enters through the inlet, the purification process continues
and clear water emerges from the outlet) valve Nos. F1 and
F4, should be opened and all other valves closed.
For treating highly turbid water Valve Nos. F1 and F4 should
be closed first. Then Valve No. F6 should be opened and external
purifying chemical be poured through the PVC Funnel. After
pouring the required chemicals valve No. F6 should be closed and
valves F1 and F4 be opened for further cycle.
At times when the equipment collects and accumulates a lot of
suspended impurities in its filter beds the need for backwashing
arises. The invention provides this system also. Backwashing is
done by discharging a high flow of water from the bottom to the
upward direction through the filter beds which serves to expand,
cleanse and hydraulically regrade the filter beds. For backwashing
Valve Nos. F2 and F3 must be opened while all other valves
should be kept closed.
During the time of backwashing the filter beds are dismantled.
In order to settle the filter beds the process of Rinsing must
be done 15 to 20 minutes after backwashing, Rinsing time valve No.
F1 and F5 should be kept opened. After rinsing is complete
Valve No. F5 should be closed and Valve No. F4 should be
opened for further cycle.
