Pumps for pool water treatment
A filtration pump circulates water through the filtration system, removing impurities and keeping the water clear. A properly sized pump ensures that the entire volume of water in the pool circulates through the filter frequently enough throughout the day. Modern models are designed to be energy-efficient, which helps keep operating costs under control.
A chemical dosing pump automatically feeds pool chemicals, such as chlorine or pH adjusters, into the pool water as needed. Automatic dosing prevents the underdosing or overdosing of chemicals and guarantees consistent water quality in all conditions.

Sand filtration
We supply suitable sand filters for projects based on the facility and application. Filter sizes range from small single-layer filters with a 45 cm diameter up to 250 cm DIN multi-layer filters. Even larger sand filters and specialty filters are available upon request.
Manufacturers of standard size filters include:
- Fluidra (Astral)
- Technol
- Waterco
Operating principle of a swimming pool sand filtration system
Sand filtration is a key component of swimming pool water treatment, which maintains water clarity by mechanically removing solid impurities. The operation of the system is based on a closed circulation, where pool water is directed through the filter tank using a filtration pump and returned to the pool purified and chemically treated.

Filter media
SAFETY DATA SHEETS (in Finnish)Quartz sand
A traditional and reliable filtration material made from natural and washed quartz. It provides stable filtration performance and good water quality. Quartz sand consists of angular sand grains whose irregular shape traps dirt effectively. The most common grain sizes are 0.7–1.2 mm (fine) and 3–5 mm (coarse).
Glass pearls
A new generation filtration material made from 100% pure glass. It provides excellent water clarity and filtration performance, as it is capable of filtering particles as small as 3 microns from the water. The material consists of small, round glass beads with a grain size of 0.5–6 mm.
Activated carbon
Filtration efficiency can be significantly improved with multi-layer filtration by adding a separate activated carbon filtration layer on top of the sand bed. Options include Anthracite H (grain size 1.4–2.5 mm) or AquaSorb activated carbon (grain size 1.7–3.6 mm), which effectively remove organic impurities from the water and improve water quality. Powdered activated carbon (PAC) is fed into the water treatment filters using a Pakdos dosing unit. The container size is 60 l.
Ultrafiltration
A membrane filtration system, or ultrafiltration, is particularly suitable for facilities where the technical room has limited floor space or a low ceiling. The minimum height requirement for the system is only about two meters, and in accordance with DIN standards, the water circulation rate can be halved compared to sand filtration.
Ultrafiltration system includes:
- Flocculation
- Pre-filtration
- Membrane filtration
- Chemical filter cleaning
- Activated carbon filtration
- Chlorination and pH adjustment
Operating principle of ultrafiltration
Ultrafiltration is an advanced pool water treatment method that produces microbe-free water by removing bacteria and viruses using precise membrane technology. The operation of the system is based on a space-saving process, where pool water is directed through ultrafiltration membranes and returned to the pool completely purified.

P4Y Automation
Our swimming pool water treatment control system is designed to enhance and simplify maintenance. The system is scalable and can be integrated with both a traditional sand filtration system and a modern ultrafiltration system.
P4Y Automation offers significant advantages for pool water treatment:
- Centralized management: All functions are integrated into a single user interface, eliminating interface issues and streamlining maintenance.
Real-time automation: The system monitors water quality and doses chemicals automatically, minimizing human error.
Cost efficiency: Intelligent control optimizes water, energy and chemical consumption based on actual demand.
Remote management: A secure remote connection enables monitoring on any device without separate license fees.
Immediate fault management: Automatic notifications enable a rapid response and remote issue resolution.
Backwash water recovery
The backwash water recovery system enables up to 50% of the sand filter backwash water to be recycled. The reverse osmosis-based method generates significant savings in water, wastewater and heating costs. Designed and manufactured in Finland, the equipment ensures fast deliveries and reliable maintenance and spare parts services.
Pool chemical dosing
Maintaining swimming pool water quality requires continuous and precise monitoring, which is best achieved through automation. Automatic measurement, control, and dosing systems ensure water purity and safety by optimizing chemical consumption according to actual needs.
Our range includes reliable solutions from industry-leading manufacturers, such as WDT’s Granudos and Prominent, which can be flexibly adapted to facilities of all sizes.
We also offer high-quality pool chemicals and photometers for professional use.
UV systems
Connecting a UV unit to the filtration cycle enhances swimming pool water treatment and significantly improves water quality. A significant benefit is also the reduction of combined chlorine in the pool water, often by up to half of its previous level. This makes the pool water more pleasant by reducing irritating chlorine compounds, and it also freshens the air in the pool area by reducing the chlorine odor.
P4Y UV systems
Durable construction and high capacity
All units are compact and easy to install. Their durable construction is based on a polished acid-resistant irradiation chamber and a corrosion-resistant outer coating. The comprehensive range offers options for flow rates up to 550 m³/h and flange sizes up to DN 300. This allows the UV system to handle the entire water volume of the filtration cycle.
Efficient monitoring and easy maintenance
Maintenance is facilitated by an automatic or manual cleaning system and a 360-degree measuring UV sensor. Operating is seamless with a user interface that features comprehensive control and monitoring functions. Maintenance planning is effortless thanks to operating hour counters and a service indicator. Additionally, the equipment can be flexibly integrated into other systems.
Operating principle of the UV system
The shortwave ultraviolet radiation produced by the UV system destroys bacteria, viruses, and other microorganisms by damaging their DNA structure. This reduces the need for chemicals and effectively removes organic matter from the pool water that is not affected by traditional filtration.
