Water treatment technologies
4 complementary approaches for pure, healthy and crystal-clear water. Each technology addresses specific needs.

Chlorine
Chlorine is the most widely used disinfectant in the world for pool water treatment. There are two types of chlorine: inorganic (sodium hypochlorite, recommended with ASIN AQUA systems) and organic (tablets, incompatible with ASIN AQUA). Sodium hypochlorite provides precise and consistent dosing through Aseko automatic systems.
- Powerful and proven disinfection
- Precise dosing with ASIN AQUA systems
- Controlled treatment costs
- Compatible with private and public pools
- Wide range of Aseko products available

Salt
Salt technology uses electrolysis of sodium chloride (NaCl) at low concentration (2-4 g/l, 10 times less than seawater) to produce chlorine naturally. This process eliminates risks associated with transporting and handling dangerous chemicals. The water is soft, pleasant for skin and eyes.
- No chemical handling required
- Soft water, pleasant for skin and eyes
- Natural chlorine production through electrolysis
- Low salt concentration (2-4 g/l)
- Reduced treatment costs in the long term

Oxygen
Oxygen technology provides chlorine-free disinfection through the synergistic action of Aseko's POOL & SPA preparations and active oxygen. Combined with FLOC+C flocculation in a coagulation mixer and AFM (Activated Filter Media) filtration, this technology minimises the chemistry needed while guaranteeing crystal-clear water.
- No chlorine in the water
- Ideal for sensitive skin and allergies
- Crystal-clear water without chemical odour
- Integrated FLOC+C flocculation
- AFM filtration for maximum efficiency

AFI - Filtration Improvement
AFI (Aseko Filtration Improvement) is a unique combination of chemistry and physics to achieve crystal-clear water with minimal aggressive disinfection. The fundamental principle: what can be filtered does not need to be oxidised. By improving filtration, the need for chemical disinfectants is drastically reduced.
- Drastic reduction of chemicals
- Principle: filter rather than oxidise
- Superior water quality
- Optimised chemistry + physics combination
- Compatible with all Aseko technologies
