AOP System Reviews

AOP reviews for swimming pools AOP systems, or advanced oxidation process for swimming pools and hot tubs, is the newest technology available to residential pool owners to help keep their swimming water clean and safe. The process involves using an oxidizer to kill bacteria and organic debris in the water...which is something that swimming pools and hot tubs have always done via chemical dosing and peripheral equipment such as electronic salt chlorinators, UV lights and ozone generators. Each of these methods of oxidizing has benefits and disadvantages. AOP systems, while similar to traditional oxidizing systems, have much greater potential for oxidizing contaminants in your pool water than any other system has been able to achieve. It does this though the creation of hydroxyl radicals, which are the most reactive oxidizers (high oxidizing potential) that are safe for human contact in water.


Hydroxyl radicals are not uncommon at all in the world around us as they are an integral component in atmospheric chemistry. Hydroxyl radicals are considered the detergent of the atmosphere as they react with pollutants as the initial stage of removing them, as well as also helping to reduce greenhouse gasses like ozone and methane. As it applies to swimming pool water chemistry, hydroxyl radicals can be generated via a synergistic pairing of ozone generation combined with germicidal UV light (Germicidal wavelength 254nm). What is most significant about this process that combines two systems already used in swimming pool water quality management, ozone and UV, is that the oxidizing potential of the hydroxyl radicals created by the ozone and UV combined is far greater than the individual values of oxidizing potential from the UV light and ozone generator individually. Hydroxyl radicals have the potential to oxidize up many times faster than ozone alone under similar testing conditions. This specific feature is the reason why hydroxyl radical based AOP systems are better than UV or ozone alone, and will continue grow in popularity in the residential (and commercial) pool market.





Faster Oxidizing Potential

how fast does AOP work If you had to describe the advantage of AOP and hydroxyl radicals in a single word, it would be "fast". The speed at which hydroxyl radicals work is the definitive advantage of AOP systems, or more so, the limitation of systems like UV lights and ozone generators. Ozone is a great example of this, since contact time with the water is one of the most important factors for how effective (or not effective) an ozone system is. This is why you will often see pools with a floor return in the deep end which would allow the tiny ozone bubbles the maximum amount of contact time with the water. UV light is slightly different than ozone in that it does not destroy pathogens, but instead alters their DNA structure which renders them unable to reproduce in a process called inactivation. Still, in order for UV to function, it requires contact time with the water and the contaminants.


In a very simplified sense, to give you a feeling for just how much faster hydroxyl radicals work than UV or ozone, imagine a room full of bacteria. If you turned on an ozone system to clean the room, imagine it will take take 10 seconds to kill over 99% of the bacteria. Now by comparison, if you turn on a germicidal UV light in the room, after less than only one second the bacteria is over 99% inactivated. Less than one second is obviously much better than 10 seconds. Using this comparison and applying hydroxyl radicals to kill the bacteria in the room instead, in the span of one second the hydroxyl radicals could oxidize all of the bacteria in the room 100,000 times over. Sure contact time with the water is not everything, and there are a ton of variables to actually consider in a real world setting, however the speed at which hydroxyl radicals work makes the AOP technology more appealing, and more promising, than any other current swimming pool water treatment system on the market.


By reducing the contact time required with the water to kill or inactivate bacteria, viruses and organic debris, you remove many of the traditional limitations of ozone and UV based systems. Now you don't need to worry about moving the water slowly past the UV light, or keeping the ozone bubbles in the water for as long as possible.


DEL Ozone Solar Eclipse Reviews

DEL Ozone is an equipment manufacturer that is synonymous with pool and spa oxidizer systems. Previously their advanced oxidation process (AOP) systems were sold under the names of Solar Eclipse 100 and Solar Eclipse 50. In 2017 the product was redesigned and rebranded as the DEL AOP 25 and the DEL AOP 50. The 25 and 50 designations refer to the size of pool these units are rated to work on, namely up to 25,000 gallons and 50,000 gallons. There is no doubt that AOP systems will become more popular for residential swimming pools in the next few years, and a trusted industry name like DEL Ozone is a great brand name manufacturer to bring these revolutionary new products to market.

Part Number: SEC-110-26
Pool Size: Up to 50,000 gallons
Voltage: 240 Volts
Flow Rate: 50 GPM Maximum
Product Status: Coming 2018


Since ozone can damage some pool systems such as covered pools where the ozone can become trapped and accumulate under the cover it is recommended that the AOP 25 and AOP 50 systems also use a mixing degas vessel (MDV) which serves to remove ozone from the system before returning water back to the pool. Not all pools need an MDV however indoor pools, pools with automatic covers and vinyl liner pools should use one for sure. The AOP 25 system requires the MDV-10-08 mixing vessel while the AOP 50 system uses the MDV-XL (MDV-100) mixing vessel, both of which will be available in 2018.


Clear Comfort Pool Reviews

Clear Comfort advertises that they are a manufacturer of chlorine free and low chlorine pool systems. Their AOP based systems were brought onto the pool market in 2014 and they are now active in both commercial and residential water treatment across the USA. These products are manufactured in Colorado and were voted by Pool & Spa News Magazine as one of the top 50 products of 2017, as well as being voted one of the best 25 new products in 2017 by Aquatics International Magazine. If you are looking for a way to reduce the amount of chlorine that your pool uses, then Clear Comfort and their AOP based systems are one of the very best options currently available.




Clear Comfort CCW100

Part Number: CCW100
Pool Size: Up to 40,000 gallons
Voltage: 120 / 240 Volts
Flow Rate: 90 GPM Maximum
Product Status: Available


Clear Comfort also makes the commercial pool CCW300, CCW300A and CCW500 AOP units. The CCW100 is also rated for commercial pool use however I strongly encourage any pool owners using these systems to still maintain a minimum of 1ppm of free chlorine at all times in the water. Even though Clear Comfort advertises low and zero chlorine pools using these systems, there is a great deal of protection afforded to bathers by chlorine. If you want more information about why you want to maintain a chlorine residual in your pool water at all times then you should read this article about chlorine free pools. If you want to reduce your chlorine demand as much as possible then the CCW100 system is a fantastic choice, and hard to beat with their manufacturer 5 year warranty as well as 90 day full satisfaction refund guarantee. Yes these systems are expensive, but if you want the latest technology to reduce your exposure to chlorine or other chemical sanitizers, then AOP is the technology you want, and Clear Comfort has one of the best AOP system on the market right now.


Prozone Eco Master Reviews

Prozone was founded in 1977 and are considered one of the pioneers of ozone and germicidal UV treatment systems. With over 1,000,000 water purification systems sold around the world, Prozone is considered one of the industry leaders for these technologies. This is largely due to the founder of Prozone, Ron Barnes, who has had an illustrious career working on NASA's Apollo 13 and Apollo 14 evaluation team and recertification team, as well as being involved with the NASA Challenger disaster evaluation team. He also went on to work for Boeing as the principal engineer on the International Space Station Freedom. In addition to these impressive accolades, Barnes also holds over 30 current US patents with the most recent relating to chlorine generators, ozone generators and advanced oxidation processing. If you are looking for an AOP system for your swimming pool then the technology developed and used in the Eco Master AOP systems from Prozone is industry leading to say the least.

Prozone Eco Master POOL

Part Number: ECO MASTER POOL
Pool Size: Up to 40,000 gallons
Voltage: 120 / 240 Volts
Flow Rate: Offline
Product Status: Available


Unlike the DEL and Clear Comfort AOP systems, the Prozone Eco Master uses an offline, venturi style installation versus the other brands which can potentially accommodate the entire flow of water from the system. The advantage of the offline system is that it does not add to the flow restriction of the plumbing system in the same way that the other "in series" installations do. Much in the same way that I would recommend a pool owner to use an offline chlorinator instead of an inline chlorinator as they are less of a flow restriction, the same can be said for an offline AOP system installation. Forcing the entire flow of the system through any piece of equipment has a fairly detrimental affect on the flow dynamics of a system. With an offline installation the flow dynamics of the system as a whole are not greatly affected.


Chlorine Alternatives For Pools

Pool owners the world over are asking about chlorine free pools or alternatives to chlorine or other chemical sanitizers. The reality of chlorine free pools is that there is no perfect solution to this problem...but AOP is getting close. The concern with any system that does not maintain a residual value in the water is that any bacteria or contaminants will sit, untreated, until they eventually are drawn through the filtration system and pass through the peripheral device whether it be a UV lamp, ozone generator or AOP system. Yes AOP is incredibly effective at oxidizing and killing bacteria and pathogens in pool water, and there is a short lived hydrogen peroxide residual from these systems, but without a free chlorine residual in the water there is an increased risk for illness to bathers.


I do not condone operating any swimming pool without chlorine or another approved chemical sanitizer that can hold a residual value in the water. If I was forced into operating a pool without chlorine, then I would absolutely look to AOP to help keep the water as safe as possible without chlorine. If you would like to learn more about why chlorine is so important you can read this article on chlorine free pools. If you would like to know more about how advanced oxidation process works, as well as the limitations of AOP, then read this article on AOP in swimming pools.
