Cleaning up of swimming pools incorporate a broad range of methods. One of the most effective methods in today’s world is ‘SALT WATER CHLORINATION’ in which the normal salt is used. In salt water chlorination, there is a chlorination system that makes use of dissolved salt. The quantity varies from 2500 PPM to 6000 PPM depending upon the size of the pool. There is a Chlorine generator, which makes use of electrolysis to generate Sodium Hypochlorite (NaCIO) and Hypochlorous Acid (HCIO), and the entire production occurs with the salt dissolved in the system. A pool having a chlorine generator can’t be considered chlorine-free, but the only difference is that there is no direct pouring down of chlorine in the water.

There is no use of free and combined available Chlorine. There is no foul odor coming from the swimming pool while using salt water chlorination system. Moreover, people will not have to suffer from eye and skin problems, which usually occurs when there is an insufficient level of free available chlorine in the pool.
It is a lot easier to produce free chlorine with ‘salt water chlorination system, as the generator makes use of electrolysis. What’s happening in the water can also be properly monitored. Though, there are other health related issues that have been detected such as bromoform, which is present in dangerous quantity in the pools having salt water chlorination system. Besides this, disinfection by-products are present in this new system as well.
A brief about the operation
There is a chlorinator cell used in the system, which incorporates of titanium plates or perforated plates placed parallel to each other.
Then, electrolysis attracts all kinds of minerals, including calcium to these plates. How much water is present in the pool and how much is the usage will determine the cleaning with an acid solution that contains one part of the Hydro-chloric acid and 15 parts of the water present in the swimming pool. It is important to stop the chlorinator after using it for a short period of time in order to avoid the stripping off the cell coating, which will be very expensive to replace. There is a stabilizer used in the saltwater pools as well, which is usually cyanuric acid, as it is very effective is stopping ultraviolet rays coming from the Sun. This acid binds the free chlorine in the swimming pool. Apart from HCL, Sulphuric acid is also used to neutralize the alkalinity of the swimming pool. But, it will also make the pH neutral and will generate sulphate ions.
Advantages and disadvantages
Incessant delivery of pure chlorine-based sanitizer to the swimming pool. This system will not be harsh on those who are sensitive to chlorine. There are certain disadvantages as well, such as the cost of buying it, the cost of maintenance and replacement cells. There are many items made up of metal, which will get corroded due to the presence of salt.
Now, there are two kinds of pool that you can use; i.e., saltwater pools and chlorine based pools.
Salt Water Swimming Pools
If you think that a salt water swimming pools don’t have chlorine, then that’s a misconception. Chlorine is present, though in low quantity when compared to the conventional chlorinated swimming pools. The chlorine is formed due to the chemical electrolysis and not added externally. The chlorine is added through a salt water generator, which is an integral part of the system. If you are afraid of your skin getting dry because of swimming, then a salt-water pool is ideal for you.
High initial and running cost
The initial charges of salt water pools can burn a hole in your pocket, and if you overcome the initial costs, then comes the running costs, which are also quite expensive. You will have to buy a salt water generator, which will generate a uniform flow of chlorine, barring the sprouting of algae in the pool, thus increasing the life of the swimming pool. To run the generator, electricity is required, and so, you will have to incur the power costs as well. It will be better to create a schedule because generator can’t run all day because if it will, then the corresponding electrical power will be consumed. If you are thinking of having the salt water pool for a long duration of time, then that’ll be a profitable venture, otherwise not.
You don’t have to regularly clean your salt water swimming pool, as just once a year would be sufficient. Cleaning pool involves various steps like draining, change of filters, scrubbing the surface and checking the chlorine generator. Out of all the four things, draining the pool and changing the filters are two most expensive and time consuming procedures. There are also possibilities of getting salt ring stains, which is a dangerous thing because it can damage the swimming pool liner because salt leads to corrosion. If you have installed lights in the pool, then those will be affected as well.
What are the chemical requirements that you need to fulfil?
When compared with the saltwater swimming pools, chlorine pools are quite cheaper. But, they are not as long-lasting as the saltwater pools. You will have to take a proper care of the pool so that it works fine and the pH balance also remains consistent week-in and week-out. You must have the required chemicals to keep swimming pool water clean and safe. You have to check whether the pH level of chlorine should be in between 7.2 and 7.6, calcium should be 200-300 PPM and alkalinity between 100 & 150 PPM. You have to make sure that these figures need to be precise according to your swimming pool. It also decides how much usage of the swimming pool is.
Maintenance of chlorine swimming pool
Chlorine swimming pools need to be checked on a constant basis due to the system used in each one of them.Salt water pools are comparatively easy to clean, and they remain clean for a long duration of time. In the Chlorine swimming pool, you will have to shock the pool in order to avoid any accumulation of bacteria. Shocking the pool is not an easy process, so make sure that you have been provided with the directions to use by the pool supplier. It is important for you to determine how much chlorine is present in the pool in order to precisely know how much shock needs to be added.
I don’t know if you know this, but chlorine is one of those chemical substances that get mixed with all kinds of human output, whether urine, sweat or saliva. The end result of this mixing is that you get ‘chloramines’. Chloramines are those components, which cause foul odor in the pool and also cause skin and eye irritation. Chlorine is apt in killing all kinds of contaminates, yet chloramines remain present in the water. Chloramines are killed more quickly in salt water swimming pools than chlorine pools.
The Wild Card Entry
If you have gone through salt water pool and chlorine pool, but not want to go with any of those, then here is one more option for you. There are certain pool disinfectant systems, which make use of UV light. These systems are totally safe to use and doesn’t require too many chemicals to operate. They use the same technology, which we all have been using at homes in our kitchens. Doesn’t ring a bell? Well, I’m talking about water filters, which make use of the UV light technology to clean up bacteria and viruses from the water. Though, this technology has not become that much popular in the pool industry, but in the years to come, it surely is going to.
It is imperative to know what actual maintenance of the pool is like and how it is done. To find out the right product, it becomes pivotal to go online and check out the reviews and feedbacks given by consumers. It is important to choose the precise product that can clean the water in the pool.
Where chlorine pools are economical, salt water pools will take some extra money out of your pocket. Chlorine pools have been there for past five decades, whereas salt water pools are barely two and a half decades old. There has been a trend that water parks and hotels are switching to salt water pools because these are more economical and easier to clean. Maintenance cost is also less, thus making them more viable for business owners.
The type of option you want to go with depends upon how passionate you are regarding swimming pool with respect to finances and usage. So, we have discussed salt water pool, chlorine pool and their comparison. You will be able to choose the right type of pool for your day-to-day usage after going through this article.
