The Four Things You Need to Know to Purchase an Ozone Generator

There are a few key things you need to know before you can purchase an ozone generator. Prior to going into subtleties, nonetheless, note that we are discussing crown release type ozone generators. These are the main sort of business/modern ozone generators. There are different sorts of ozone generators, yet non crown release units are generally for use in little scope applications, creating regularly not exactly a large portion of a pound for each day or under 10 grams for every hour of ozone.

This article will survey the key determination factors and how it identifies with different applications for ozone and the effect on the expense of an ozone generator.

The key elements include:

1. Yield: This is how much ozone the machine makes, typically cited in grams every hour or pounds every day.

2. Fixation: Ozone can be created at various focuses going from 1-12 weight percent. The convergence of ozone affects most applications and furthermore influences machine yield.

3. Gas Feed: you should have a wellspring of feed gas containing oxygen, there are three decisions: dry air, oxygen concentrated from air or bought oxygen (either as fluid oxygen (LOX) or packed oxygen in chambers).

4. Generator Cooling: Ozone generator make heat that should be eliminated, the choices for eliminating this warmth are air cooling or water cooling.

Choosing the correct blend of highlights relies firmly upon the application. For instance, in water treatment applications higher centralizations of озон are utilized while in air treatment applications lower focuses can be chosen.

Ozone Generator Output

This is the main factor in choosing an ozone generator. The measure of ozone required depends on the application necessities. On the off chance that the ozone is being utilized for expulsion of natural impurities from water, the measure of ozone is relative to the measure of natural in the water, the productivity of the ozone natural response and the effectiveness of dissolving the ozone into the water.

As a particular model, ozone is regularly used to decrease compound oxygen interest (COD) in water. COD is estimated in ppm (milligrams per liter – mg/l). It ordinarily takes 2 mg of ozone for every mg of COD to eliminate the COD. In this way, on the off chance that we needed to treat 10,000 liters for every hour of water containing 50 ppm of COD we would require:

10,000 liters/hour X 50 mg/l COD x 2 mg Ozone/mg COD = 1,000,000 mg/hour

1,000,000 mg/hour = 1,000 g/hour = 1 kg/hour

Thus, we would have to disintegrate 1 kg/h of ozone (or 52.8 pounds every day of ozone)

Under 100% of the ozone infused in the water breaks up, so we need to realize the ozone move effectiveness. A very much planned venturi infusion framework can break down at any rate 90% of the ozone. For the case above, you would require 1 kg/h ÷ 0.90 = 1.11 kg/h (58.7 pounds every day of ozone). This is the measure of ozone we would need to deliver at the focused on fixation to break up the 1 kg/h of ozone into water.

Significant: A given framework will deliver less ozone as the convergence of ozone increments. Ozone move productivity, the rate at which ozone breaks up into water increments with expanding ozone fixation. The two components will decide the last size of the machine required.

Deciding the measure of ozone needed, aside from the least difficult applications, requires research facility or pilot examines joined with a designing assessment to choose the best possible harmony between ozone portion, fixation and generator size. Typically, an ozone generator organization won’t have the option to give this data. On the off chance that they can help, there will be an extra expense for leading the examinations.

Ozone Concentration

As indicated above, ozone focus can influence both the viability of ozone in a given application and the measure of ozone that can be created from a given ozone generator. Basically, high focus ozone costs more, yet can accomplish more in specific applications. Business crown release frameworks produce somewhere in the range of 1 weight percent ozone to 12 weight percent ozone. Gas treatment applications ordinarily utilize the 1-3 percent range while water treatment application regularly utilize 5-10 percent.

A significant part of ozone focus is in contrasting distinctive ozone generators. Makers utilize various bases for asserting the ostensible yield of an ozone generator. Typically, you need to peruse the fine print to perceive what focus they use to guarantee a given creation rate.

For instance:

Yield (g/h) Concentration (%) Price

Provider #1 60 6 $5,500

Provider #2 60 4 $3,800

At comparable fixations the outcomes would appear to be unique:

Provider #2 60 6 $6,000

(g/h = grams/hour)

Thus, to decently contrast machines you need with know the measure of ozone delivered at a centralization of interest alongside the expense of the generator. This will permit you to think about ozone generators “one type to it’s logical counterpart”.

Ozone Generator Gas Feed

Ozone generators can run on different oxygen sources such dry air, concentrated oxygen or bought oxygen as a feed gas. Initial, a short conversation of feed gases. Initially, ozone generators mostly worked with air as the feed gas. Air contains about 20% oxygen and just the oxygen can be changed over to ozone. Utilizing air as the feed gas, the greatest monetary convergence of ozone that can be acquired is around 3 weight percent.

Likewise, the air should be very dry since dampness diminishes ozone yield and will harm the ozone generator. To deliver a sensible grouping of ozone, the air should have a dryness as estimated by the dew purpose of about – 100 degrees Fahrenheit. This implies that in 1,000,000 pieces of air there is just one section water. This degree of dryness requires uncommon dryers to eliminate the moistness. Refrigerated dryers found on certain blowers can just reach about a dew purpose of – 40 degrees Fahrenheit.

Utilizing a feed gas with oxygen focus more noteworthy than 90% permits the ozone fixation to increment to the 5-10 percent range. Also, ozone generators produce higher yields of ozone as far as pounds every day or grams every hour utilizing oxygen versus air.

Bought oxygen ordinarily is extremely dry because of the assembling cycle utilized. It tends to be bought as a packed gas in chambers or as a fluid. The volume that can be put away as a compacted gas is a lot more modest than in fluid structure. Along these lines, except if the ozone generator is in effect just utilized for short measures of time, packed gas is presumably not a decent feed gas alternative.

Fluid oxygen, at times alluded to as LOX, can be provided in little holders or conveyed in truck load amounts. It should be vanished to the gas stage preceding use. It is the most practical type of oxygen if the oxygen creation plant isn’t excessively far away.

Another alternative is to focus oxygen from air in a cycle known as weight swing retention (PSA). In this cycle a material called a sub-atomic strainer ingests both water and nitrogen from air leaving mostly oxygen in the gas stream. Oxygen groupings of 90-95% are promptly accomplished. The cycle is done in both little scope just as enormous mechanical frameworks. Little applications incorporate convenient oxygen frameworks for individuals that need supplemental oxygen for relaxing.

Thus, in outline the principle feed gases for ozone are dry air, PSA oxygen or fluid oxygen. Some ozone generators can run on each of the three feed gas, yet this isn’t generally the situation. Some ozone generator providers plan their frameworks to run either on air or some type of higher focus oxygen. It is essential to know this early since it probably won’t be conceivable to switch once the unit is bought. The central issue here is that in the event that you need higher fixation, you should utilize oxygen feed gas framework with a generator intended to utilize this gas.

Ozone Generator Cooling

All ozone generators make heat because of the ozone creation measure. The generator should be kept cool since as the gas temperature builds the ozone will crush down spirit into oxygen making the cycle wasteful. Ozone generator producers give their ozone yield and focus information dependent on a particular working temperature, typically 68-72 degrees Fahrenheit.

Each degree over the specified temperature brings about a reduction of creation. For instance, for each degree increment in temperature the pace of ozone creation diminishes by 0.6% in certain frameworks. Thus, if the machine should work at 72 degrees and it is really worked at 82 degrees the creation would be diminished by 6%. A few generators shut themselves down totally at specific temperatures to forestall harm. So cooling is a basic issue for the generator

There are two normal cooling strategies, air cooling with fans and water cooling. Air cooling is less effective and lessens the size of the ozone generator that can be constructed. All in all, ozone age of more than 10 pound for each day can’t be promptly finished with air cooled ozone frameworks.

Water cooled frameworks come in a few varieties. Shut circle frameworks utilize a water chiller to cool the water and cycle it persistently through the ozone generator. Water normally enters the ozone generator at around 60 degrees F and leaves at 70 degrees F.

Backhanded cooling circles utilizing ground water or other water sources are likewise utilized. Here a warmth exchanger has one side associated with the ozone generator with a reusing circle and on the opposite side a once through progression of water accessible at the site. Regularly the water temperature is higher than ideal and a bigger generator should be bought to make up for the deficiency of creation.

The decision of the sort of water cooling and the utilization of a chiller depends on a designing investigation to adjust the expense of the expanded generator size with the expense of cooling the water.
