Is the Ozone system superior to the uv system for commercial pools?

Answer 1

AnswerAn ozone system consists of two basic components that ensure optimum performance at the lowest operating cost:

1. The ozone generation system

2. The ozone management system

The ozone generation system creates ozone gas from on-board oxygen concentrators. The ozone management system efficiently dissolves the gas into the water while ensuring that no undissolved ozone is available to off-gas in the pool equipment room or at the pool water surface. Ozone dose is automatically controlled with an oxidation reduction potential (ORP) controller/monitor maintaining proper ozone levels in the water.

Together, the ozone generator and ozone management system operate in unison and are easily installed to an existing public pool as a side-stream to the pool's main filtration system. The ozone is introduced after the filtration (and heater), and before the chlorine feeder. The side-stream flow is normally 15 to 25 percent of the main flow, depending on the size and type of pool. The output of ozone is increased as the water quantity, water temperature or organic loading increases.

Ozone is a safe and efficacious antimicrobial oxidizer. In public recreational water, ozone is used in conjunction with chlorine to enhance pool water clarity and quality and swimmer protection with ozone's potent and rapid oxidation of organic and inorganic compounds.

Ozone is cost-effective, uses little energy, is safe for pool patrons, and helps to protect the HVAC system from structural degradation.

Answer 2

Ozone systems for pools almost always use ozone to produce ions (usually hypobromous ion, although various ozone + metal ion systems exist too). So the difference is in how the ions are made. Note that none of these systems "clean" pools, they just tend to keep the pool clean, usually without "boiling" chlorine gas into the atmosphere, and with smaller effects on pool hardness.

Answer 3

Ozone is a powerful oxidizer, and it is used primarily for disinfection in Swimming Pools. It is particularly good for cryptosporidium, and others, requiring smaller doses and/or shorter contact times to achieve kill.

It also will reactivate bromide ion to hypobromous acid, so one can use bromine as the primary steriliant in the pool itself. Bromine has a lower vapor pressure than chlorine, so you don't need to add it as often (and this saves money on adjusting alkalinity as well).

Finally, it will act as a flocculant, improving the sand filter's ability to remove detritus. The molecules that ozone attacks are easier for Biology to use as food sources, so your filter will also be more efficient that way.

In general, ozone is applied just before the sand filter, and ozone does not survive more than a few millimeters into the sand bed.

There are a few pools that use ozone as the primary sterilant also, but this takes a much larger ozone generator.

DUCK!!!!!

Answer 4

Ozone is an oxidizer, like chlorine. An ozone generator injects ozone into your pool to burn off the bad stuff and takes the place of chlorine. Do research and ask questions - chlorine, bromine, and ozone all have their pluses and minuses.

Answer 5

It is common to hear confusion about the difference between ozone and UV systems. They are, in fact, completely different technologies but confusion may come from UV-generated ozone that was used in residential pools and spas before breakthrough compact CD ozone generators came on the scene in the late 1990s. Today, UV generated ozone is never used in commercial pool settings because the systems cannot make enough ozone to benefit the pool water. CD generated ozone, on the other hand, is extremely safe and effective for pool water sanitation.

Both Ozone and UV provide effective reduction of Cryptosporidium (Crypto), however, there are clear differences in other areas of concern for commercial aquatics designers and operators. The advantage, in these cases, goes to Ozone over UV.

Ozone is a powerful oxidizer.Ozone gas dissolves in water to kill microorganisms, destroy organics that create chloramines, and breaks down existing chloramines by oxidation. Meanwhile, UV light inactivates microorganisms and breaks down chloramines with light energy, but this is only possible while the water is in the UV chamber, and as long as the water has no turbidity. Once the flow leaves the chamber no further process occurs. UV provides no oxidation except as trace amounts as a result of the formation of a limited number of hydroxyl free radicals. Ozone and UV are comparable in cost.Ozone and UV technologies are comparably priced. Operational costs of each system vary with the local price of electricity. However, the minimal maintenance and reduced chemical requirements of an ozone system create significant benefits. Meanwhile, UV lamps must be replaced every 3 to 12 months and must be figured into the maintenance costs for these systems.
