Design choices in building a swimming pool
A swimming pool is a complex project in terms of building, engineering, but also chemical processing of the water. There are two solutions for building swimming pools.
Concrete:
Pools made of reinforced concrete are custom built to the size and plans that suit the owner.
Their construction requires marking out and digging, taking into account the plan and the elevation that will determine their dimensions and depth. Such pools have the advantage of being long lasting and can be designed to suit your needs.
Prefabricated:
These pools are made of metal and plastic, but they have many drawbacks, which is why our company does not undertake to build them, but only to provide maintenance for them.
1. Recirculation using pool skimmers
Recirculation using skimmers is the simplest construction-wise and is indicated for small or medium sized rectangular pools. The water is channelled to the pump through the skimmers. At the same time the water that is returned to the swimming pool through the return openings creates a current which brings debris to the surface towards the skimmers. That is why the correct positioning of the return openings compared to that of the skimmer openings plays a decisive role in proper water recirculation and the cleanliness of a swimming pool.
The system has two compartments:
- The swimming pool
- The pump room (the greater part of which can be incorporated into the pool or it can be limited within a shaft).
The water enters from the skimmer line and from the bottom of the pool and passes through a sand filter, the chlorinator and the pH regulator before returning to the pool.
2. Recirculation and pool filtering through overflow
The pump absorbs 70% of the quantity recirculated from the overflow tank and 30% from the bottom shaft. The water overflows into the perimeter channel or the cascade channel and returns to the overflow tank through pipes.
The system comprises three compartments:
- The swimming pool
- The overflow tank.
- The pump room.
The water enters through the overflow tank and pool bottom and passes through the sand filter, the chlorinator and the pH regulator before returning to the pool.
The pump room consists of the following components:
- Circulation pump
- Sand filter
- Chlorinator and pH regulator
- Electrical Panel
Pool water treatment
Main principles
- The pool water pH should be regulated at 7.2 – 7.6 throughout the season’s duration. The pH is regulated by adding PH- or PH+ respectively
- Free chlorine concentration in pool should not fall below 0.5ppm. Increase chorine intake (tablet, powder, granules) after each measurement.
- The pool filters and bottom should always be clean and the water clear. Check and clean daily.
- Water recirculation should be adjusted so that the entire volume of water is filtered every at least 4 hours.The recirculation pump should be set properly (at the beginning of the season).
- Η συγκέντρωση των ισοκυανουρικων να μην ξεπερνάει την τιμή των 100ppm. Σε περίπτωση που ξεπεράσει την ανώτερη τιμή των 100ppm τότε πρέπει να απορριφθεί ποσότητα νερού από την πισίνα και να συμπληρωθεί με φρέσκο. Επίσης χρειάζεται συχνός έλεγχος των ισοκυανουρικων για να αποφευχθεί υπερκατανάλωση χλωρίου.
