Start saving

An inBlue solution compared to any other efficient public pool filter system is extremely energy and water saving. Here is how:



Factor 10 to 100
less energy

The gravity operated inBlue drum filter uses a factor 10 to 100 less energy than conventional sand or DE filters. Since only a fraction of the water needs to be filtered by sand or DE filters, the overall energy consumption decreases drastically. Most of the water simply can be pumped directly back to the pool from the balance tank.

Sand or DE filters, which are traditionally used in pools, operate with a pressure drop when backwashed from 1 to 3 meters plus a typical differential pressure of 2 to 10 meters. The inBlue drum filter on the other hand operates with a pressure drop when backwashed from only 0.1 to 0.2 meters plus a typical differential pressure of 0.2 to 0.3 meters.



Drum filter saves water consumption

The inBlue drum filter backwashes often to ensure that skin cells present in the water are removed before they can be dissolved. Backwash frequency is determined by bather load, but most often backwash takes place several times per hour. But be aware! Since only a few cups of water is needed per backwash, the drum filter in total uses less than one tenth of the water used during a weekly sand filter backwash. Sludge from the drum filter is concentrated skin cells.



Much less sand or DE filters

Since 90 to 95 percent of particles present in the water are removed by the InBlue drum filter, only little work is left for sand or DE filters. Based on bather load and general system design, our calculation models determine flow needed for sand or DE filters. In average less than 25% of the main flow is sand or DE filtered. 

Calculation of water hydraulics

inBlue modulates water hydraulics for each pool we work with. Using computational fluid dynamics (CFD) we use side inlet tubes to create water currents to the optimal rotation speed given by CFD. The currents accelerate cleaning of all areas of the pool, enhancing water and air quality. No need for traditional nozzles with meters of pressure drop.



No prefilter needed before pumps in an inBlue system

No prefilter is needed before pumps in an inBlue system. Due to the inBlue drum filter, no further filtration is required. Both stand-alone and basket filters integrated in pumps generate meters of headloss.



Ceramic pumps and frequency converters with eco-drive

Selection of pumping technology in a pool filtration system is of the utmost importance. inBlue's main pumps are super efficient with ceramic coating to maintain the lowest possible energy consumption over their entire lifespan. Most pumps are equipped with frequency converters and are PLC controlled for automatic power saving at night and/or when not needed.
