ozone users to note . why ozone measurement is a must

Ozone is a gas . So is Nitrogen, oxygen , Carbon dioxide , helium, Argon .But what is the difference between ozone and the other gases ?    Other gases are prepared by air separation and they all can be stored in cylinders as they are very stable gases. When you can store the gases , they can be measured , especially because they are in the pure form  .  So using them is easier and measurable .

What about ozone ?  Ozone is the only gas that is synthesized . Ozone gas does not occur naturally unlike other gases . Ozone gas is very unstable , cannot be stored and hence need to be produced and utilized in situ . Also Unlike other gases , ozone gas is never pure and does not exist alone. It carries with it oxygen gas  /other gases . Hence you can not measure ozone separately like other gases . Hence you measure concentration only and use this is determine the ozone weight.

Here is the catch. since measurement of concentration of ozone is possible only with expensive analyzers , the industry is faced with a problem that is the root cause of process failures . Users of large ozone systems do not want to pay a little more for the analyzer and end up loosing the whole . Unscrupulous manufacturers thrive    .

Recently there was an issue faced by a CEPT  of a tannery effluent  , which had the most experienced member in leather technology , failing to observe these precautions. They purchased and installed 15 Kg ozone system from a Mumbai ozone manufacturer ( that too 15 numbers , 1 Kg system) and found out that each of the 1 Kg system is producing just 200 grams . This is a government funded project .  A little bit of awareness could have saved crores of investment . The loss was only  to the end user organization ( tax payers money)   and they nearly concluded another large order to the same supplier until awareness was forced onto them .

Lesson to be learnt : Don’t adopt modular systems. If you want 15 Kg , go for a 15 kg system. Always ensure you buy an ozone analyzer along with the ozone system and demand process guarantees . Buy ozone only from companies who are technology based and who have history of good world wide references .  Get ozone specialists evaluate specifications

If you still consider economy as the only criteria , than no one is to be blamed except you .

Making Ozone Use safer In India – We value life

Designing a Safe vent ozone distructor

Ozone distructors have compromised design if they

1) are not designed for the flow of water flow and capacity of the contact tank

2) If catalysts are used and they are not sized appropriately. They need sufficient surface area , sufficient particle size and sufficient air velocity to work efficiently. A manufacturer of these catalyst will tell you all about this

3) they do not incorporate a moisture separator if required by design of contact tank

4) They do not take care of temperature control

Vent ozone distructors for SS tanks: These are for smaller applications where the capacity of the ozone contact tanks vary from 3 KL to 30 KL total capacity. It is normal to incorporate in the design of these contact tanks off gas vent that facilitates tank breathing during filling and emptying. The size of these vents is in accordance to the capacity of the contact tank.   the contact tanks vents have to be correctly designed , else there could be an implosion of the contact tank .

Vent ozone distructors are of 2 types .The thermal ozone distructors utilize heat to destroy ozone.  The temperature that has to be reached for 100% ozone destruction within a few seconds would be as high as above 250-350 Deg cel . This is very challenging as the surface of the distructor gets extremely hot and effective control of the temperature rise assumes importance. The power requirement will be sometimes more than the power required for the ozone production.  Thermal type vent distructors are not very common for small applications and are very difficult to source. Few reputed companies manufacture larger thermal type but they are very expensive and high on operation costs

The catalytic ozone distructors are most common and very reliable if designed well


Note the Ozone distructor mounted on a skid on the left side of the picture

They are easy to install, operate and maintain. operate and maintain. They contain specialized catalyst that have proven record of destroying ozone . These catalyst lasts a long time  ( 3-4 years) if the ozone distructors  are designed well.

Catalysts used in vent ozone distructors have to be used carefully. They are poisonous and so the design and the installation of the vent ozone distructor should prevent this catalyst of falling into the tank when they crumble. Moisture from the ozone tank can clog these catalysts, and prevent tank breathing, causing implosion of ozone contact tanks. The ozone distructor design must prevent crumbling and clogging of the catalyst, enable free tank breathing.

These are small steps we at OTSIL take to make ozone use safer in India . Contact us for well designed ozone distructors . Be safe .


Buyers must exercise their right while buying an ozone generator

Recently I was called to a fairly large company to check on an ozone system installed for water treatment . They were not getting results . They were sold a 500 grams ozone system by an Indian manufacturer . against our will be were coaxed to check the ozone production and found that the unit was generating only 70  grams . This was confirmed also by the actual power consumption of the unit . There was nothing the buyer could do at this stage as the manufacture was giving ll sorts of excuses for non performances and shifting the blame to the engineering of the contact tanks, water quality and what not.

these situations do not happen in developed countries and it is high time we became sensitive to these tall claims of few irresponsible ozone manufactures .Buyers , consultants  must exercise their rights  enforcing performance as claimed/guaranteed

Today OTSIL has replaced more than 30 units of other ozone manufacturers within the last 2 years – All of them within warranty period. . We do not actually like it  and are frustrated ourselves . Will it Change ?

Thank You to my mentors

Rip Rice & Allan Pryor and few others not to mention, have been stalwarts in the ozone Industry There is not one article on ozone that would not have their names as references . They created world ozone awareness . If they had been to themselves , if they had been selfish , I could imagine what the status of the ozone Industry would be today.

Some of other colleagues in ozone  whom I want to openly  acknowledge , Guys who have taught me so much and made me what I am today.  Jean Yves Perrot ( where are you Sir ?)  Loius Benard Wiart , Jean Christophe Hostachy  , Florian Mills ( Suez) ,  Harald Staple and Marco Rosner and many others .  Over 20 years association . These  are some who have been my mentors . My inspiration . Thank you guys . You have been wholly selfless.

time to pay back , I have complied this Ozone 101 . A very simple compilation that put together all what I have been taught in ozone . Join Ozone users In India LinkedIn group I created and request one and know all about ozone . We need more members in India to join  with world  Group . this brings befit to India
