Transparency in Business is the essence to survive

OTSIL  has always believed in being transparency to its clients . While being transparent to its employees is a managements philosophy , being transparent to its clients is Mandatory .  One article that was published has impressed us       : https://www.entrepreneur.com/article/295739

OTSIL s transparency can be seen by the clients in the information we provide to clients in design, testing procedures , and documentation we provide with our equipment . We call it GMAAP   ( Good Manufacturing and Application practices )  http://www.otsil.net/manufacturing&application-practices.html.

Never has there been a single  instant where we hide even the smallest and least important information from our clients . If we are at fault , we readily accept and offer remedial solutions. We do not run away .

Transparency is the essence . Come to OTSIL for ozone solutions and you would realize why we are most preferred in India

Reliable large ozone systems from OTSIL

There are very few large ozone generators manufactures around the world . Local manufacturers have have claimed to have installed large ozone systems have all failed . This is because you cannot manufacture ozone systems without basic research facility   . You cannot test your product at site . There should be an history of reliable working of the ozone generator .  This has made ozone systems high capital intensive and too dependent on few manufacturers .

Other important issues that are lacking is the availability of local ozone expertise and above all local service network for instant service. All claims of fast service would be exposed when there is a shut down for months for spare parts or service personnel to arrive at site.  You cannot force the clients to maintain inventory of expensive spare parts .

No ozone manufacture around the world manufacturer all the four components of the ozone system –  The power Board , the inverter , the transformer and the dielectrics . Except the dielectrics , all the components are out sourced . This appear to be the main reason for long delivery periods , delays in services and supply of spare parts

The presence of local engineering team is of utmost importance in large projects . This does not happen most of the time .

the other factor is that large ozone systems being assembled like computers and supplied to clients .  This is a big danger. The individual components of Inverter, transformer, dielectrics have to be integrated to work in unison and doing this at site is a disaster in waiting .

Oxygen is the heart of the ozone system. Experience reveal that most of the time it is the oxygen that is the culprit for ozone system failure . There need to be an integrated approach with the oxygen supplier and team work is essential

OTSIL provides one more reliable choice of large imported ozone systems in India . All components self manufactured , large working references around the world, established R & D activities on ozone technology, local service net work and highly knowledgeable local engineering team. Working in Unison with the oxygen supplier is an additional  advantage .

Contact OTSIL for large ozone systems. Do not cut and paste specifications as this would surely cut down on the choice available to your client and increase his project costs

Making Ozone Use Safer In India – We value Life Ozone Safety Tip 1

Ozone Safety   TIP 1

Ozone systems are high voltage equipments. Voltage can exceed 9000 Volts.  The dielectrics that generate ozone are like Hugh capacitors. They can produce electrical shocks even after the power is disconnected.  Safety should come first. Some of the ozone generators manufactured locally have least consideration of safety aspects. They have the high voltage dielectrics mounted outside and behind the ozone control panel.  There is no protection against accidental contact by operators. I have seen in one installation in Mumbai where fencing is built around the ozone generator with lock and keys and this is recommended by the manufacturer. This is a ridiculous suggestion and totally misleading the client. We at OTSIL put safety foremost. All high voltage parts of our equipments are safely enclosed and made inaccessible to operators.  Our systems would pass any international safety audit. We must learn from International rules on safety standards and must also learn to   value life

As part of “Making ozone use safer in India “we will carry on this awareness programme so that in course of time we  reach international safety standards. Economy should not replace Safety

 

Reappearance of Pseudomanas after Dechlorination with SMBS

Many water treatment consultants would have faced this situation . Pseudomonas Nil when measured in the presence of residual chlorine . But the moment you use SMBS and remove the residual  chlorine , the Pseudomonas reappears . This is not uncommon if you know the behavioral pattern of these gram negative pathogens . They become sessile under unfavorable conditions and proliferate when the conditions are in their favor . When you use ozone in these conditions you need to be very careful and consider various factors to ensure total removal of these pathogens.  Many solution providers resort to high ozone dose without  really taking care the root cause

We have successfully provided solutions to many Pharmaceutical companies and shown how this should be done. Merely introducing high doses of  ozone will have very little effect.  Residual chlorine in process water does not mean that you have eradicated gram negative pathogens . Contact OTSIL  for reliable solutions in these situations .

AOX LEVELS – OZONE SOLUTIONS

AOX levels – Ozone solution

Halogenated organic compounds are by products formed when chlorine is used as disinfectant in water and waste water

What is AOX
Adsorbable organically bound halogens (AOX) are a group of chemicals which can be adsorbed from water onto activated carbon. Most AOXs are compounds containing chlorine, but some also contain the similar elements bromine or iodine. The properties of AOXs vary: some evaporate easily (such as trichloromethane or chloroform); some are complex molecules such as dioxins and furans. THMs are part of AOX . AOX once formed cannot be destroyed by any chemical means or process. They have to be removed from water or waste water
Industry Water Guzzlers .Both the power plants as well as paper and pulp plant use more than 60% of the total water used in the country. Therefore they also discharge large quantities of water as waste  water . Both the power plants as well as the paper and pulp plants use lots of chlorine in their water treatment/process etc.

Where does it come from?

The main sources of AOX are from the chlorine chemicals used for treating cooling water in power plants and chlorine used to bleach fibres in the paper and pulp industry. AOX are  also formed during the routine chlorination (disinfection) of drinking water, swimming pools and industrial effluents.
How might it affect the environment?
Some AOXs are toxic to fish and aquatic organisms – Even at low concentrations. Many are persistent and have a tendency to accumulate in the environment which causes concern at global level. AOX once formed remains , either in the ground , polluting water source or in humans when they are consumed with water
How might exposure to it affect human health?
Exposure of AOXs to humans can occur through eating contaminated food ,, drinking contaminated water – and the fact that AOXs can concentrate up the food chain means that humans could be exposed to dangerous levels. The type and severity of adverse effects depend on the AOX in question. Some (such as dioxins) are known to be very toxic.  Many AOX/THMs are cancerous to humans and known to be precursors to rectum and colon cancer
In the UK (including Scotland) releases of AOX are controlled through the Pollution Prevention and Control (PPC) regulations. Chlorinated AOXs have been on the European Commission’s “black list” of toxic substances since 1976. In India pollution control board provide levels of AOX that industries must control in their waste water discharge

For example ,according the German classification  system  regarding AOX levels in river water, a concentration below 5mgCl/l is slightly polluted, 5–20mgCl/l is moderately polluted, 20–40mgCl/l is strongly polluted, and over 40mg Cl/l is very strongly polluted.17 This classification is relatively severe. It is Normal to  chose the maximum AOX data in river water as the nonpolluting level

In India paper and pulp plants have already taken conscious efforts to reduce AOX  levels  by replacing part of chlorine in their process with Ozone . ( ITC is the first plant ) The main by product of ozone chemistry is oxygen  it is an ideal choice to limit the formation of chlorinated byproducts (AOX) formed during conventional bleaching  processes . Similarly power plants have already taken conscious efforts to replace chlorine with ozone in cooling water treatment and in waste water treatment .

MY NEW ACTIVITY – BLOGGING FOR OZONE AWARENESS

25 years of ozone experience now. It is time to pay back. For one to one interactions , I have started this blog and trying to spend what ever spare time is available with me on this activity . Initiating discussions, on various ozone topics could solicit interested persons to participate and try gather useful information. Internet is useful. But how many persons know which is right and which is wrong information. I have also taken time to prepare an Ozone 101 hand book of ozone and it is ready now. This is a non commercial activity of mine and is for free distribution to those showing genuine interest in ozone. The catch – you must register yourself in the linkedIn group I have created- ozone users in India . Go to www.otsil.net and click on the Join ozone users in India and follow instructions . If you find it difficult just send me an email with all your contact details etc . I will mail you the pdf copy to you . You can also use that platform for discussions , there you could get information from others through their experience . V.Baratharaj
