Dry deck fountains are currently very popular and you can find this type of interactive play fountains in various locations, from public parks and parks of shopping malls and water parks, where they provide interactivity for young children. A common factor frequently found in these fountains is that they seek to bring rhythm and movement to the water, turning the space around them into an attractive place for visitors.
What is Dry deck fountains?
Dry deck fountains are characterized by having a hidden structure, below our feet, which means that we can have a fountain in the same space as a dry environment, when the fountain is not running. We could use the space for other events when fountain is switched off. The entire network of piping, cabling, nozzles been placed in hidden structure. Obviously it would have access openings to service the hidden space.
We have Various type of nozzles for different spray type. With different connection sizes different height shall be achieved in relation with selection of pumps. This allows to achieve different dry deck feeling in every project. Every project is unique as its shape of the layout, orientation of nozzles (which clone the shape of water body) & the type of nozzles. The spray height of nozzle, the movement of nozzle can be variated with quantity of pumps.
In dry deck fountain we shall able to achieve
Nozzles moving up & down in a SET,
Multiple SET of nozzles moving up & down by different pumps,
Variation in movement of the nozzles,
Individual nozzles controlled independently but with a common pump for a SET of nozzles
Individual nozzles controlled independently with independent pumps.
All these options comes with lights as that is spectacular in evenings.
The below PATTERN display would allow to understand better.
Different possibilities of dry deck fountain
Two major possibilities on civil point of construction.
For first option, we use a concrete channel, a structure that contains the water for the proper operation of the fountain. This water returns to the tank through a grid placed around it, and through the dry fountain kit, which includes a grill for return and drainage to the tank.
For second option, we use PITS on the locations of nozzles which comes with incoming water supply, Electrical supply & drain provisions. A balancing tank been kept separately in suitable location where after is stored & send back through nozzles & circulates.
The use of a Filtration system is essential & mandatory for better performance of Dry deck nozzles.
Four major possibilities on Nozzle operation point of view
For First simple & competitive option, we use set of nozzles with single or multiple pumps with VFD.
For Second option, we use individual nozzles controlled by TWIN solenoid valves with single or multiple pumps with VFD.
For Third option, we use SPECIAL WATERSWITCH nozzles synced with single or multiple pumps with VFD.
For Fourth option, we use nozzles with individual DMX pumps. This Pattern shall give opportunity “to create FANTASTIC CHOREOGRAPHIC effect”
All four options comes with lights & SS grating as flush arrangement.

- UV-C light is a very powerful germicide. It deactivates and renders harmless waterborne pathogens that are completely unaffected by chlorine based disinfectants. Examples of dangerous pathogens (viruses and cysts) neutralized by UV-C light are Cryptosporidium parvum and Giardia lamblia; chlorine will not affect these. UV-C is effective against all microorganisms for example also the Pseudomonas, papillomavirus and e-coli. A secondary disinfectant must be added to the water to ensure that the water actually in the swimming pool is disinfectant as well as disinfected. The most commonly used secondary disinfectants are chlorine based chemicals.
- UV-C kills destroys the chloramines (The smell of pool water changes to better. This is because of the lack of chloramines in the swimming pool). As a by-product of the disinfection process, chlorine combines with bathers’ body fluids in the pool water and form chloramines. Chloramines are unpleasant substances that cause eye, skin and nose irritation, breathing difficulties in young children, an unpleasant smell and last but not least, damage to tiles, grouts, handrails and other fittings. UV light destroys chloramines, thus reducing or even practically eliminating the undesirable side effects mentioned above of the use of chlorine based disinfectants.
- Because UV-C disinfects the water, you don’t need chlorine to disinfect the water, you only need chlorines to make it disinfectant. This makes sure you are able to decrease the amount of chlorine to a max of 80% (depending on the type of pool). Chlorine increases the PH value, Less chlorine means less increase of PH. This means you also need less PH or another acid. Less acid makes sure the bicarbonate level is longer stable and needs less corrections. When it’s a saltwater pool, less Chlorine means less salt. You also need less shock. UV-C kills the bad chloramines, this means you’ll need to do less maintenance to the swimming pool due to chloramines. This decreases the maintenance costs.
- UV-C is effective against all microorganisms.
A Review of Swimming Pool Sanitization Methods
Many homeowners struggle while trying to select sanitization systems for their swimming pools because they have many options to choose from. The truth is: no single system is best. Different swimming pools call for different systems. You should therefore consider a number of variables when selecting a sanitization system, including initial costs, maintenance costs, maintenance tasks, climate, and number of swimmers. In this article, I briefly discuss five popular swimming pool sanitization methods and list advantages and disadvantages of each.
Chlorine has historically been the most widely-used chemical for swimming pool sanitization, though several alternative sanitation methods have recently gained popularity. It kills bacteria by undergoing a simple chemical reaction. In this chemical reaction, chlorine breaks down into hypochlorous acid and hypochlorite ions, which then oxidize bacteria until they are neutralized or destroyed.
Advantages of Chlorine Sanitization
- Chlorine has a long half-life and can therefore be stored for long periods of time.
- It is available to consumers in many different forms. It can be found as a solid granules, liquid, gas.
- Chlorine has a residual effect: not only does it neutralize contaminants when it is first added to swimming pool water, but it also continues to neutralize long afterward.
Disadvantages of Chlorine Sanitization
- By-products of chlorine are chloramines and trihalomethanes (THMs), which cause skin and eye irritation to swimmers. Also create bad odour.
- After being added to a swimming pool, chlorine dissipates very quickly. Swimming pools that utilize chlorine must therefore be regularly tested and maintained.
- Chlorine By-products have been associated with a number of health issues, including respiratory problems.
Salt chlorine generators utilize a chemical process called electrolysis to form hypochlorous acid from salt and water. The key characteristic that distinguishes salt chlorine from its sanitizing counterparts is its ability to recycle itself. After the hypochlorous acid sanitizes the swimming pool water, it reverts back to salt, and then the process repeats. Salt chlorine generators have gained much popularity with homeowners recently, and the market for them is likely to expand further in the near future.
Advantages of Salt Chlorine Sanitization
- Because the chlorine generated is so concentrated at the point of production (inside the salt cell), swimming pool water is super chlorinated when it passes through the energized cell. This super chlorination helps combat the buildup of chloramines.
- Swimmers experience less skin and eye irritation in salt chlorine swimming pools than in traditionally-chlorinated swimming pools.
- Salt chlorine produces nearly neutral pH levels, so few additional swimming pool chemicals are required to balance the pH levels in salt chlorine swimming pools.
Disadvantages of Salt Chlorine Sanitization
- Salt chlorine generators typically cost between more as its spares.
- Salt cells must be replaced once every three to five years.
- Excessive salt concentration is corrosive and can contribute to the breakdown of handrails, lighting systems and other equipment.
UV Systems has proved that ultraviolet treatment with low levels of free chlorine has major benefits over any of these traditional methods.
The greatest benefit of UV treatment is that short-wave ultraviolet light has a photo-oxidation effect that destroys chloramines and other toxic by-products of chlorine. This is done without adding any further swimming pool chemicals to the water. Much less chlorine needs to be used to provide bacterial control, so water quality and atmospheric conditions are considerably improved.
The primary UV disinfection process destroys all bacteria passing through the treatment plant. In particular, and unlike ozone systems, this protects bathers against bacteria in the filter media re-entering the pool.
Advantages of UV Sanitization
- UV destroys these pollutants releasing free chlorine back to pool.
- UV acts instantly. Only low level chlorine residuals are necessary.
- UV cuts costs by releasing the combined chlorine
- Maintenance costs of UV equipment are lower, and do not increase significantly with age.
Disadvantages of UV Sanitization
- UV water purifier kill bacteria and viruses but does not remove dissolved impurities
Ozone is an unstable, inorganic gas that is created when free oxygen atoms collide with oxygen molecules. It is manufactured by subjecting oxygen molecules to either a high-voltage ionization process or to ultraviolet radiation. Most ozone generators utilize the high-voltage ionization process because it results in a much higher concentration of ozone (20% by the high-voltage ionization process versus 5% by ultraviolet radiation).
Advantages of Ozone Sanitization
- Ozone is a strong oxidizer. Specifically, it is 100 times stronger than chlorine.· It reduces the need for swimming pool maintenance: it breaks down filter-clogging contaminants such as grease and oils.
- Ozone has no effect on the pH levels of swimming pools. Swimming pools that utilize ozone, therefore, require much less pH adjustment. This translates to less chemical usage.
Disadvantages of Ozone Sanitization
- Ozone has a short half-life: it cannot be stored, but instead must be used soon after it is produced, and is only effective as it mixes with the water in the return line. After it returns to the pool, Ozone is released back to the atmosphere.
- It alone is not a sufficient sanitization method for most swimming pools, as it cannot eliminate all swimming pool contaminants. However, Ozone is compatible with Chlorine or Bromine.
- Ozone gas is harmful in high concentrations.
UV is the best and simple sanitation methods used in modern days. Specially for Indian customers and the quality of labour force we use to maintain pools, UV is undoubtedly best solution to maintain pool. To make more effective UV comes with Ozone these days.
