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 .
