Gas Chlorine – Advantages

Chlorine gas is having 100 % chlorine. You can control the chlorination
continuously and uniformly with chlorinator. Bleaching powder being
hygroscopic in nature, absorbs moisture from air and will become a pasty
mass. Hence storage & handling is a difficult task, Rapidly looses chlorine
on storage, Leads to commercial loss on storage.
Due to rapidly depleting chlorine concentration in bleaching powder, exact
chlorine dosage at the time of dosing is never known. Bleaching powder
solution preparation is a laborious process involving mixing, settling,
decanting of clear chlorine solution, transferring to dosing equipment etc.
If the solution has high residue, then lime will deposit inside pipelines and
equipment causing choking of lines and pumps.
While adding to water bleaching powder will be having only 25 % chlorine,
you have to add minimum 4 Kgs of bleaching powder to get 1.0 kg
chlorine. Uniform chlorination will not available with bleaching Powder.
Gas Chlorine – Most Cost-Effective

Cost of one kg chlorine gas will be maximum Rs 55.00 ,all inclusive up to
your Pump House Cost of 4 Kgs Bleaching powder ,to get 1 kg chlorine
will be Rs 100.00 ,all inclusive up to your Pump House. Sodium Hypo
Chlorite is having only 10 % Chlorine you have to add minimum 10 Ltrs of
the same to get 1.0 Kg chlorine sodium hypochlorite also degrades over
time and loss up to 50 % of its potency in the first 30 Days
1
• Gas Chlorine contains 100% available chlorine per kg
2
• Bleaching powder contains only 25 % of available
• chlorine/kg
3
• Sodium Hypochlorite contains approximately 12.5%
available chlorine per gallon
Gas Chlorine – The Safest

Safety regarding chlorine isn't about the chlorine itself, but about the
accidental release of gas, and the ability to contain it if that happens. Chlorine
gas, by itself, is not explosive. Chlorine gas is delivered in a system designed
for gas use. Modern day gas delivery systems are based on a vacuum,
instead of pressure, which further ensures safety, since a broken pipe will not
exhaust gas in a vacuum-driven system: no gas is released. When the news
reports a chlorine “gas” release, many times the exposure is due to offgassing of hypochlorite. The chlorine gas would not have been released if the
hypochlorite had not been involved in a violent, sometimes explosive,
chemical reaction, usually due to accidental mixing of chemicals.

Based on chlorine content, it is necessary to feed different amounts of each
to achieve the same disinfection level.
1 Kg Chlorine
= 4 Kg Bleaching Powder
1 Kg chlorine = 10 Ltrs of Sodium Hypochlorite
The result is a monthly cost comparison that shows that gas chlorine is
clearly more cost-efficient. In addition, equipment, transportation and
operating costs must be factored into cost equations, with the result also
showing that gas chlorine will reduce costs.
Gas Chlorine – Choice Method
A large percentage of industries
use products that are dependent
upon chlorine. This affects us
everyday in the food we eat and
the water we drink. From farming
to soda bottling, well water to
municipal water facilities, chlorine
is used to make our water safer.
The poultry, dairy and livestock
industries rely upon gas
chlorinated water for

washing, sanitizing and animal
drinking water.Meat processing
plants depend upon it for both
processing and chilling water; using
it to spray the equipment and
products. Beverage bottling plants
use gas chlorine to sanitize their
facilities.
Fruit and vegetable processing
plants use it to wash down all
produce. Gas chlorinated water is
used in canneries to cool cans after
cooking, as well as for facility
sanitation

Automatic Vacuum Regulator with Teflon diaphragm and Teflon/Silver
working parts, which will be stopped the chlorine flow from the cylinder in
case of power failure/water shortage. Water passes through the injector to
produce the required vacuum, this automatic vacuum regulator will be
reduced the pressure of chlorine to a constant level. The Automatic Vacuum
Regulator is the heart of vacuum feed chlorinators. Our exclusive design
ensures safe handling of chlorine gas with minimum risk.
Differential Pressure Regulator A compensating differential pressure
regulator with Teflon diaphragm and working parts to maintain the constant
down stream pressure across the Rota Meter.
Rota Meter A borosilicate glass Rota meter with scale and Teflon float to
measure the flow of chlorine gas Calibrated for various capacities. Accuracy
of this Rota meter will be +or-2%.

Control Valve A flow regulating pressure valve to maintain the constant flow
of required chlorine gas.
Injector An Injector to create the required vacuum at a minimum water
pressure of 0.5 Kg/cm2 . Motive water flowing through the injector generates
vacuum which turns open the Automatic Vacuum Regulator open and allows
the flow of chlorine through the system. Chlorine gas and water will get mixed
here to form chlorine solution.

Pressure Breaker A vacuum pressure breaker to prevent the possibility of
water being drawn into the chlorinator and chlorine cylinder. The system is
also provided with pressure relief valve, vacuum relief valve, check valve,
drain relief valve…etc. to ensure the safety of both men and machinery.

Woolman – An Introduction
Chlorination
Powered by WoolMan
Wool Man Chlorinator as per IS:10553 Part II has been designed by taking into
account of its physical and chemical properties – viz its reaction with metal,
solubility in water, behavior at different temperature and its hazards.
Chlorine gas, greenish yellow in colour, two and half times heavier than air
reacts with almost all metals. Hence we are using only Teflon, the highly
resistant engineering plastic for chlorine gas. In our chlorinator chlorine gas in
passing through filters and valves made out of Teflon. Since the Teflon is
having very low mechanical strength we are using PVC composite FRP for
outside protection

Purpose of Chlorination for Potable and Swimming Pool Water
Certain diseases like infectious Hepatitis, Typhoid, Cholera etc. are caused
through impure water. In addition, some types of bacteria cause distaste and
impact of colour and odour to water. The only and readily available and
economical solution for the above is chlorination.
Surface water resources, normally are polluted.It needs extensive and
thorough treatment and to meet this requirement chlorination is performed.
Chlorine when added to water takes 15-30 minutes of retention time to react
with all substances present in water.
Woolman – Design and Operation
Chlorination
Powered by WoolMan
Wool Man make vacuum feed chlorinators are having the latest Vacuum
Technology. This semi automatic Chlorinator will develop the required
Vacuum(300hg) with a water pressure of just 0.5kg/cm2 which is suitable for
up to 5kgs/hr Chlorinator. An interpolation in water flow will stop the flow of
Chlorine gas at Vacuum regulator. This injector is also fitted with a positive
acting non return valve. The purpose of which is to prevent water gaining
access to the system during non-operational periods. The operating pressure
of the injecting water supply, vacuum pressure and chlorine pressure are
indicated on pressure gauges.
