The solution

• Hydraulic CFX 3D pool models removes dead zones and lower needed pressure to move particles to outlets.

• Chlorine distribution is perfected In Hydrotech drum sieves more than 90% of particles are removed within hours and wasted to sewer in a concentrated stream

• Captura sand filters are backwashed daily so that particles are flushed out before dissolving.

• Captura filters can be installed with a very low pressure demand Ultraaqua membrane systems filters all pool water daily to 0,03 micron, which is 100 times finer than possible with sand filters! Ultraaqua membranes filters reuse water from sand filters so that water demand for backwash are reduced by a factor 10, even with daily backwash compared to traditional backwash once a week!

• Nitrogen originating from urine and sweat is dissolved and will together with chlorine form chloramines also called combined chlorine. With the Ultraaqua Multiray UV, combined chlorine can be destroyed resulting in a dramatic concentration drop

• THM is formed when chlorine reacts with dissolved organics. The primary THM is chloroform that is easily stripped out even in a small side stream. The Ultraaqua THM stripper is designed for this specific task and cuts THM to half concentration in a simple effective way

• The Electrocell Chlor-o-Safe chlorine factory delivers pure chlorine in low concentration, avoiding THM and combined chlorine formation in the dosage point

• Hydraulic CFX 3D ventilation models focused on THM and chloramine ventilation combined with thermic comfort and condensation considerations leads to new ventilation principles
