Pharma Process Water – Why ozone is can be the better choice

Blogging for ozone awareness   .

Ozone or Chlorine  . Mechanism of action , chemistry of reactions , eco friendly  all points towards Ozone . Cost is one aspect that can be a deterrent. But when you look at the advantages you get over chlorine ( and UV) , the choice is on Ozone .  All process water treatment schemes must include ozone.  Effectiveness against gram negative Bacteria, removal of Endotoxin liberated during bacterial destruction , removal of bio films , viral deactivation ,  color and odour removal, removal of heavy metals and and physical properties such as flocculation and many more properties .

But take care . ozone is not a solution for all water treatment issues . Ozone does not perform magic and need careful consideration of design aspects and importantly safety aspects

Is Ozone Technology Really Expensive

Is Ozone technology really expensive ?  Not really

You look at ozone only when you exhaust all other avenues . You look at ozone as an insurance for a consistent and reliable result to confirm Statutory requirements. Ozone will allow you to remain in Business

Ozone applications can be made cost effective ( I mean value for money)  if  correct solutions are provided. Recently we were asked to evaluate an ozone proposal for reduction of COD in a chemical industry. We found that with modification of pH of the effluent , it really brings down the ozone requirement to half. The client was surprised . When you are not well , you do not go to quacks . If you go it is at your own risk. Same analogy you can relate to ozone applications . You go to persons who can provide you with solutions and give you a reliable system to compliment the solution. Not to persons who offer solutions based on internet reference .

The next aspect is health implications . Why do you see that there is so much of discussions in the reduction of THMs , removal of pesticides and micro pollutants from water- world over  ?   We see only the costs of the ozone system, but never look at the other side – Health implications and costs associated with it . We are not aware how much of health costs we can save just by providing good quality drinking water . We save costs , and make our nation healthy .  Ozone is the savior here

We introduce lots of contaminants when we conduct our business . We must have social obligations and do our bit . We must make the world a better place for next generations

Learning From The Best

logging for Ozone Awareness

Reliability , Performance and Service- learning from the Best This was an event 10 years ago. India’s largest Ozone generator by Wedeco , arrival of a 230 kg per hour containerized system. Technological marvel . We have been involved right from this time ,till the time it was commissioned and handed over to the client . As a company we learnt so much from this installation . We knew exactly what a large ozone system has to be like, in terms of engineering , construction & safety aspects , how to , trouble shoot and how to provide quality service . Experience of a life time .We adopt similar engineering standards for all our ozone equipment. No wonder our systems are preferred wherever reliability , performance and service are prime most importance to clients   CONTACT US FOR LARGE OZONE SYSTEMS 9840149184

Single Large Ozone System V Modular Systems – Spares Requirement

There are only few ozone companies around the world who can manufacture single large ozone systems upto 50 kg ozone per hour. Just 4-5 of them . Companies who do not have technology to manufacture single large systems propose small modular system in multiple of 2 kgs .ozone manufacturers in India have limitations in their capabilities of manufacturing single large ozone systems. Claiming to manufacture one is different from producing one that has been time tested , proven reliable  is different

Water treatment consultants , EPC contractors  in India , and End users must realize that such modular proposals are out dated now. .They should stop encouraging such designs . There are ozone systems that run 24 x7 x 365 x many years without a single shut down . There are numerous installations around the world without spare ozone systems

For example only in india this happens ; requirement of say  18 kg machine is often proposed as 9×2 kg units, and often taking the stance of providing spare capacity to increase reliability in the application! Such design would in fact decrease the reliability since it would be very difficult to maintain 9
units at a time, increasing the requirement of spare parts, machine down time,
and frequency of preventive maintenance apart from increased CAPEX.

If you have the choice to go for a single large unit, why go for modular or multiple units. Today companies like ITC Bhardrachalam are operating the world’s single largest ozone system of 200 kg per hour for their process, without any spare ozone system, but with a foolproof, periodic preventive maintenance schedule . Lets learn from them. Read on

Column OZONE -ozone dose in STP

How many times have we come cross complaints from clients that they  never get the required quality of water with ozone .  Most of the time , we have noted that ozone dose is compromised to keep the cost of system low to beat competitors . Clients fall for this trap by unscrupulous sellers . Spending a little more time in evaluating the process, equipment and the supplier would probably solve the clients headache

We can get the horse up to the pond , but drinking has to be done by the horse itself .  Ozone is not to be blamed for ones own mistake.

Why Process Failures With Ozone ? A Close Look At It

With ozone , we should not have any process failures. Such is its prowess. But we keep hearing that many issues crop up with ozone applications including miserable process failures . This can be avoided if with a little consideration of  design parameters . Normally does not happen any where in Europe ,US and in other developed countries . Economy overtakes everything else in India Prospective  users , consultants , water treatment experts can stop it  and make competition more healthy .  Read on .AUGUST 2018 Process Failures

Unsafe Ozone Systems With Iso 9001-2015 Certification

Blogging for Ozone awareness- we value life . We make safety as our  habit .

Recently we were called to check out on one ozone system and we were surprised to see the quality of the system . An unsafe machine waiting for disaster to happen. Surprised ? It is an ISO 9001-2015 certified . Where around the world would you find such units ? Your guess is right !!

Economy does not mean you compromise on safety . Safety is everyone’s right and need to be imbibed as a habit .  Ozone has been safe for as long as it has been used and no incidence have ever  happened anywhere around the world. Let India not be the first one

ozone systems are not sold in showrooms. so we guess the buyer may not have the opportunity to evaluate the quality . But there are ways .

Making Ozone use safer in India . We value life

Ozone & Plastics

Ozone Applications are increasing in India. Numerous instances have been noticed that applications are decided without due considerations to the materials of construction of pipes , containers etc  .We provide below some information on the use of different type of plastics and Ozone’s effect on them.

Two group of plastics are discussed here ; Plastics  termed  as Thermoplastic materials and other group of plastics are the Thermosetting Plastics.  They find numerous use in Industries  and each type of plastics are used  for different purposes dependent on the physical & chemical properties of each.

The effects of ozone on each of these materials will depend totally on the configuration of  the polymers that  make up the plastics. Crossed linked plastics such as poly polypropylene, poly- ethylene , poly- vinyl chloride and silicone or fluorine combined plastics are sufficiently impervious to ozone to enable their use in direct contact.

Most of the packaged  water plants all over the world use plastics in some form or the other and the knowledge of each of these will help understand the likely effects with the use of ozone.

From a careful  study of  different kind of plastics  , some forms of polymers are readily attacked by ozone and are not recommended , there are other forms that are quite resistant and  take a longer time for effects of ozone. and others attacked immediately and not recommended.

Since most of the packaged water manufacturers prefer residual ozone, and they invariably use PET Bottles, Poly Carbonate Jars,   PP Filters, that are all polymer materials , the question of whether they are safe with ozone is frequently asked. The effects of ozone in the long run could unzip some of these polymers  to form by- products , Even though  they are all dose, concentration  and time related , we should never take this risk

For example poly-carbonate has been shown to be very resistant to UV and like water is  classified as an universal solvent. Ozone can also be classified as an universal reactant-  the only question is how much does it react. Through practical experience, it is very insignificant.  For that matter ,  Ozone is also supposed to be Corrosive to Stainless Steel .But the corrosion is concentration and time related and therefore Stainless steel is regarded safe  with the use of Ozone. In fact many ordinary plastics that give out smell (the popular PVC tank) can also be held suspicious,  more than ozone which imparts no flavor to the water. The action of ozone on plastics also depends on whether Ozone is used as a gas  or solution..  For example Nylon appears to break down faster when in contact with  ozone-air mixture than ozone solution

Some care that could be observed while using ozone would include:

  • Do not use ozone before cartridge filtration in packaged water process
  • Do not store fresh ozonated water in PVC containers ( use ploy carbonate instead)
  • Use CPVC /SS pipes preferably if water is being used for drinking.
  • Store freshly ozonated drinking water in SS containers instead
  • For prospective ozone users check for ozone reactions on MOC of containers/pipes before you use them.

Many of the  reported ozone reactions on materials are time concentration related and many of the toxic effects have never been proven .
