How To Set Up Ozone Generator

In this interview, Jesper Kedström, Sales Manager at Primozone, talks to AZoCleanTech most the successful installation of ozone generators.

How would you define a successful installation of an ozone generator, and what are the main considerations you must make when optimizing an installation?

When choosing an ozone generator, it is important to look at the cost for the complete system, not only the ozone generators. If you choose a generator that produces ozone at a lower concentration, the cost for oxygen equipment and production will be unnecessary high.

I therefore recommend installing and running the ozone generators at concentrations at or to a higher place 13% wt. The higher concentration and post-obit lower gas flow will, in many ways, do good you in the design of the rest of the system.

We always recommend to filter the oxygen in two steps and have the pressure regulator just before the ozone generator. This way the input gas pressure level does not depend on the filter condition. Earlier attaching the oxygen connection to the generator is should always be purged. No exceptions!

To minimize the risk of water being pushed backwards in the ozone piping, causing potential damage, we recommend all installations to be equipped with a backflow protection organization. The standard check valve is just not plenty. It has to be an active solution that closes automatically, is opened only when told to by the generator or control system and sends feedback to the generator or control system with organization condition. Otherwise, if it closes and the generators doesn't terminate, the risk for harm to ability supplies and reactors are imminent.

If your system has need for back-up, a organization controller that allows multiple units to work as i will minimize the demand for redundant capacity. Past calculation a "back up unit of measurement", just instead of having information technology in standby, running all units at all times but at reduced duty level, the demand for redundant capacity is kept to a minimum.

At the same time, the time for recovery after a failure is minimal. When running an ozone organization of multiple units, the need for redundancy can be as low as twenty%. That is 5 units for the demand and one units for backup capacity, all units running at the aforementioned time, simply at a reduced duty level of 83% (5/half dozen). A design similar this reduces CAPEX by forty%.

With the previously mentioned higher ozone concentration of at least 13% wt, the gas volume is only 50% of the standard ozone generators running at 6-7% wt, and only 25% of the air fed units.

What is the main function of the Primozone® LOX-booster and how does information technology work?

When using LOX instead of on-site generated oxygen, it is of import to accept an optimal amount of nitrogen mixed in to the LOX, which is ofttimes neglected. An incorrect amount of nitrogen can atomic number 82 to reduced chapters and production of nitrogen byproducts that can transform into dangerous products like nitric acid when they come up into contact with h2o.

Using a Primozone® LOX-booster, or equivalent, that seamlessly adjusts the nitrogen level according to the gas catamenia will improve the ozone production and subtract the need for maintenance.

How exercise you lot ensure that an ozone generator doesn't overheat during operation?

When cooling an ozone generator organisation, the preferred solution is using a closed loop. Wether the water in the loop is cooled electrically with a chiller or a estrus exchanger is non actually of import, merely more dependent on the situation.

Using a closed loop reduces the risk for bio fouling and lime scale in the ozone generator, which over time will build upward and subtract the cooling effect. Using cooling water for the complete system, including the power supplies, will subtract the demand for air conditioning the ozone generator room.

The air conditioning system can actually be minimized by introducing an airdryer system similar the Primozone® GD. The GD dries the ambient air earlier it is introduced within the generator casing.

What are the challenges with distributing ozone to more than 1 injection point?

Instead of using multiple units when having more than one injection betoken, a single ozone generator (system) together with an ozone distribution system is a great solution. These used to be a hurting to adjust until the Primozone® ODM came along.

The ODM is controlled by a system controller, and you lot fix the demand for each injection point at the organization controller. It non only adjusts the menstruum at each injection point, simply too adjusts the ozone product accordingly i.e. it is a five 2d adjustment at the system controller instead of a 24-hour interval's piece of work to adjust the system.

In what ways can you optimize the dissolution of ozone in water?

As the dissolution system is dependent on the gas book, it is important to keep the gas volume every bit depression equally possible. This way, the toll for booster pumps and injectors is decreased to a minimum.

But the biggest savings is not in CAPEX just in OPEX, as bigger pumps need more power and over fourth dimension this is a huge cost. Too, of course, the cost for oxygen is reduced by the aforementioned ratio every bit the gas book.

As for a mass transfer system, I prefer using a static mixer similar Statiflo GDS, as it not merely is a more free energy efficient solution, just besides gives a better dissolution than a venturi injector based solution. Dome diffusers are cheap only tend to waste matter the hard earned coin that you have invested into producing ozone, every bit the mass transfer is very poor.

What is the Primozone® BFP backflow protector and how does it prevent ozone generators from existence filled with water?

Prior to the mass transfer arrangement, a dorsum period protector should ever be installed. It is important that BFP not only closes when affected past water, but is controlled by the ozone generator or system controller.

A proficient backflow protector should be completely integrated in the organization: open when ozone production starts, closed when it stops or water is coming and providing feedback to the ozone generator or system controller. This is how the Primozone® BFP backflow protector works.

What about remainder ozone. How would you recommend destructing that?

When taking care of the not-dissolved and reacted ozone, the higher concentration comes in again, considering of the smaller volumes that have to be treated.

With the smaller gas volumes, the free energy required for heating the off gas is reduced, the corporeality of catalysts is reduced, and coin is saved. When operating an ozone destructor, it is important to know that the unit of measurement is working at its best.

With the Primozone® DXF ozone destructor, this is piece of cake. This unit has, for case, high and low temperature alarms, which I remember are a must! You don't want unheated moist air passing through the catalyst, neither do you desire the unit to overheat.

When the unit has a built in fan, the Primozone unit of measurement has the possibility of entering a fix signal value and also having a reading fed back to the control organisation. If the system is properly integrated, the system controller will automatically adjust the set up point for the ozone destructor fan and heater elements according to the product of ozone.

How practise y'all see the ozone generation market progressing over the next decade?

The market place for municipal and industrial ozone systems will continue to grow but the grounds for the decision making will modify. The end customer will demand more energy efficient solutions and the only way to get there is to use a higher concentration of ozone. Higher ozone concentration reduces the price for LOX or oxygen generation as well as the energy cost for the dissolution system and ozone destruction units.

How will Primozone® be a part of this change?

Primozone is already setting the standard by redefining ozone technology™ and changing the way ozone solutions are designed.

We strive to always provide the most energy and price efficient solutions, and are setting a benchmark in the market. We volition continue to offer this and meet the customers demand.
