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 .

Safety First – Hopes of a Pool owner

Swimming pools were once a upon a time an essential part of high net worth individuals. Today the higher middle class income group have joined this club. One common aspect of these individuals is that they are busy and find very little time for recreations. Hence they develop recreation facilities in their homes. Swimming pool is one important recreation facility in the home. They also provide owners ways of maintaining health and an effective exercise that can replace Gym going and also walks and it comes right at their home

Swimming pools are expected to be clean and the water must be bacteria free. Water can be a dangerous source of spreading infections. Also chlorine that has been used to keep this water clean is also responsible for many side effects caused by swimming pools. Ozone has come to the rescue and has become an essential part of swimming pool water treatment. Ozone has to perform this role for the pool owner. The pool owner hopes that the equipments suggested by the pool builder perform. He wants bacteria free water

Pool owner’s problem: He does not know if his water is bacteria free. Also getting the water tested regularly could be an issue. All he can measure is residual chlorine and hope the level he maintains provides him with clean water. But we all know residual chlorine achievement does not guarantee bacteria free water. Chlorine may be measured and we measure only residual total chlorine and not active chlorine and it is this active chlorine is important. These are reasons why an ozone treatment provides a solution. Ozone with this residual chlorine could solve his problem

A correctly designed ozone system can provide this guarantee as it is far more powerful than chlorine. Dose required is small and contact time required only in seconds. So maintaining a small residual chlorine level with ozonation will almost guarantee the pool owner a safe pool

What is the Pool owner’s problem today? He buys an ozone system and expects it performs and keep his pool safe. However in today’s Scenario, he is not sure if the ozone system is working and performing. He is not sure if the ozone system is delivering the correct quantity of ozone. He would not even know if his ozone system is working or not until one fine day he finds that his pool is breeding pathogens. In most cases pool owners find that his ozone system works only for a few months and the rest of the months he is unaware.

We are sure many pool builders face these issues but are helpless as they have to face the wrath of the pool owner

Role of a pool builder:  A builder is an important link between the pool owner and the ozone supplier. He has an important role to play to ensure pool safety .He depends on correct information from the ozone supplier. He needs an insurance that the ozone system is producing the ozone it is required  to produce and that an indication that the ozone is working.

Ozone measurement: ozone measuring instruments are expensive and can cost half the cost of a pool filtration system. This is the only reason why the pool owner feels so frustrated after having purchased an ozone system. He is only hoping all the time .

How OTSIL will help your swimming pool clients: OTSIL  R & D development provides an option for the pool client to know the Health of the ozone system. The state of Art EOPI technology comes at very small incremental price to the client. An EOPI will indicate the ozone production, it will help diagnose ozone system faults, it will indicate if the ozone system is working or not , all through a PLC display system . There are no probes or expensive analyzers. This is the best that can happen to the ozone industry

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 .

Using the correct catalysts in a Vent Ozone Distructor ( VOD)

VOD,s are deployed for destroying residual ozone from the vents of Ozone contact tanks .  VODs are 2 types , one being Thermal and the other Catalytic. Choosing the correct catalysts for the catalytic type is utmost important. Many Ozone distructors available in India are locally made with no consideration of design. Most of them have activated carbon as catalysts . 

This is out of ignorance. Activated carbon are used to strip residual ozone from water  and it is very effective here. But when used as catalysts for VODs they can be very dangerous. Firstly they genearte heat during adsorption . Then it has been noted that some Carbon Monoxide is formed as a side reaction and this is not safe .  So when ever you opt for VODs , check out on the catalysts . Request   MSD of the catalysts .  . Be safe . Use ozone safely . Contact OTSIL for safe ozone distructors .  We guarantee 100% vent ozone destruction .

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 ?

OZONE SAFETY TIP – 2

Ozone Generators are like capacitors . They operate at very high Voltage. The dielectrics can store power even when the mains are off . Do not operate ozone systems with panel doors open. It is advisable for users not to service systems by themselves unless they have been sufficiently trained or under supervision of manufacture.  Always disconnect power before you attempt to service an ozone system . Always ground the electrodes first before service. This grounding will discharge an accumulated power within the dielectrics.  A good ozone system will provide for these safety. It is manufactures responsibility to warn users .Safety manuals should be provided. safety training should be part of handing over of systems

Also ozone systems have strong electro magnetic fields . It is important for the user to know that persons with pace makers should not be allowed to go near an operating ozone system . The electro magnetic fields could cause the pace make to misbehave . Have you been told about this earlier ?
