Learning about the crucial components of a swimming pool can be immensely beneficial for both you and your pool. It will aid you in maintaining it on a daily basis and prove useful in tackling any issues that may arise from time to time.

Maintaining your pool can be a difficult task without a good understanding of its anatomy.

Skimmer Pool :

Overflow Pool :

Eight Essential Pool Parts

All pools share the same fundamental eight parts, regardless of any additional equipment or accessories that may be purchased.

• Skimmer/ Overflow fittings/ channel
• Main drain
• Suction line(s)
• Pump
• Filter
• Return lines
• Return inlets
• Vacuum point.

Once you have an understanding of the function of each pool component, it will become evident why some are placed on the suction side of the pool, while others are on the delivery side of the filter.

The Suction Side

This is the side of the pool that sucks in water and pushes to the filtration system, beginning the circulation process.

Skimmers

These are plastic buckets that built into the side of the pool to house skimmer baskets, which are there to catch larger debris such as leaves, twigs, bugs, and anything else that’s too large to go through your filter

When pool water enters the skimmer, it commences its journey through the pool’s filtration system

Overflow fittings/ channel

If it is an overflow pool, a channel would be placed on the pool water level to allow water to circulate around.

Main Drain

Typically situated in the floor of the pool’s deep end, the main drain is seldom used to drain the pool. Its usual role is the same as the skimmers, but it operates from the bottom of the pool, resulting in more effective circulation by drawing water from both the top via the skimmers and the bottom via the main drain.

Note: To minimize suction force in the event of a blockage of one of the drains by an object or person, newer inground pools are often equipped with two main drains as a safety feature. In contrast, older inground pools may not have two main drains, making pool safety practices even more important.

Vacuum point

A point connects with pipes to pump suction for manual cleaning.

Suction Lines

Typically constructed of UPVC, these pipes carry the pool water from the skimmer to the pump. Additionally carry water from main drain and vacuum point.

The Filtration System

The filtration system comprises the pool pump and pool filter.

The Pump

Pool water doesn’t just fall into the skimmers. The pool pump contains an impeller, which spins fast enough to create a vacuum that pulls the water into the filtration system.

Pool pumps are categorized by their horsepower since the impeller is powered by a motor. Typically, these pumps come in sizes ranging from ¾ to 3 horsepower. The appropriate pump size you need will vary depending on the size of your pool. The larger the pool, the more horsepower the pump will need to move the higher volume of water.

The pump alters the force exerted on the water from pulling to pushing as it passes through. The pump then pushes the water into the filter.

The Filter

Although sanitizers such as chlorine can eliminate viruses and bacteria, they only perform half the task of purifying the water. The filter completes the remaining process by removing fine debris, tiny particles, and in some cases, even bacteria that might have bypassed the sanitizer.

Pool filters are available in various types as media which determines the quality of cleaning. Sand, Glass media, Glass beads are few used in great extent. Each of them has its own pros and cons, but all are effective and easy to maintain.

The Delivery Side

This side of the pool pushes water from the filtration system back into the pool, completing the circulation process.

Return Lines

The opposite of the suction lines, but also made of UPVC, they carry pool water from the filter to the return inlets.

Return Inlets

After the water has been filtered and passed through the return lines, it makes its way to the return inlets, where it is reintroduced back into the pool.

The return inlets in the pool have a dual function – not only do they facilitate the re-entry of water back into the pool, but they also push the water around the pool. This aids in directing water towards the skimmers and any surface debris, allowing it to be collected in the skimmer basket.

Tip: To achieve that circulation in the pool, and if there are two or more return inlets, it is advisable to angle some of them downwards towards the floor in a specific direction, either left or right. This helps to create a circular flow and aids in dislodging debris from the bottom of the pool by directing the inlets downwards.

Additional Equipment

Pool Heater

While not considered an essential part of a swimming pool, a pool heater can enhance your swimming experience by providing warmth and extending your pool season. It doesn’t, however, contribute to the pool’s filtration or circulation processes.

You can find pool heaters suitable for both in-ground and above-ground pools, and there are several heating methods available to choose from, including natural gas, propane, electric, and solar. And they work more efficiently with a solar pool cover.

Heating your pool is worth considering if you’re not fond of cold water or wish to prolong your swimming season.

Chemical Feeder

This handy little piece of equipment simplifies the pool sanitization process. You only need to fill it with the specific sanitizer that the feeder is designed to use, such as chlorine, bromine, or a mineral cartridge, connect it, and then not have to worry about adding sanitizer for a while.

This is the last piece of equipment in your filtration line. The order of equipment is as follows:

Important: When connecting both a pool heater and a chemical feeder to your filtration system, it’s crucial to ensure that they are installed in the correct order. The water should pass through them in the following sequence:

• Pump
• Filter
• Heater
• Chemical Feeder

If the chemical feeder is positioned before the heater, the chemical-laden water can damage the heater over time.

Conclusion

By understanding the basic anatomy of a pool, you can ensure proper maintenance for a clear and clean pool all season long, allowing you and your loved ones to fully enjoy it.

1. Heat pump should be installed in a place where free air circulation is available. Heat pump generates heat from atmospheric air.
2. Ensure 1000mm of clearance all-around of the heat pump to allow air circulation and access for maintenance.
3. Do not block the top air exit for top mounted fan models. Shade shall be provided 2000mm above from top of heat pump.
4. Avoid positioning heat pump in such a way that the control panel does not face directly Sunrays.
5. Heat pump must be placed in proper levelled civil floor. even if it is installed in landscaping area proper pedestal to heat pump to be made & installed.
6. Distance between heat pump and pool should be as short as possible to reduce heat loss and pressure loss in the pipe work.
7. Isolator switch should be installed (by a qualified electrician) near the heat pump.
8. Electrical supply to the heat pump must be protected by an MCB & ELCB.
9. Air inlets and outlets must not be obstructed or blocked by any means including shrubs & bushes.
10. Our heat pumps are additionally protected with VMR to avoid & protect electrical fluctuation in incoming.
11. Heat pump must be installed in downstream, after pool filter so filtered water passes through it.
12. Each model heat pump performs with minimum- maximum water flow rate. If the flow is higher than required, need to be bypassed. If the flow is lower than required, system would not work & you need to check pump flow.
13. Correct sizing Pipework to be installed between pool & heat pump to ensure correct flow & pressure is achieved at heat pump.

Introduction:

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

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

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

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.
