Two generic methods
to remove Radon in Water

• GAC (tank filled with carbon)
• Aeration (water is bubbled to release the radon)

An AERATION systems remove up to 99% of the radon in the water.
 A GAC can remove as much as 95% but typically a single tank removes about 80%

GAC can only be used for Radon in Water that is less than 20,000 pCi/l or less.

Granular activated carbon (GAC) systems are simple and less costly than aeration but often provide poor long term performance.  They require yearly or bi-yearly carbon replacement.  The carbon inside the unit needs to be removed and replaced which is a messy time consuming and expensive job.

 





This is the schematic of a bubbling system or aeration system.

Radon in the water moves into the air bubbles created by the aeration system.

The exhaust is then vented above the roof.

This is an "AIRaider" system that aerates the water in three separate tanks inside the unit.

The grey motor is the blower that provides the aeration.

The green tank is the re-pressurization tank and re-pressurization pump

We reduced radon in water with this unit from 62,760 Pci/L to 642 pCi/L

This is the inside of an aeration system with the top removed.

Note the bubbles in the first three tanks.

The left tank is the treated water





This is system with iron in the water.  Aeration systems require yearly or bi-yearly check-ups to check the
operation of the solenoids and accumulation of minerals in the aerator tank.

This is a Shallow Tray aeration system.

The water is bubbled in a shallow tray before falling into the bottom of the system.

The blue tank on the left is the re-pressurization tank and the re-pressurization pump.


These are the "Bubble-Up" spray aeration units that use a pump on demand water supply system rather than a pre-pressurized water tank.

We installed the smaller unit in a home with limited space and reduced the radon in water from 58,295 pCi/L to 508 pCi/L

All mechanical water treatment systems can have issues that a qualified installer knows how to avoid and to be able to fix them

The picture below is an Airwell system.  It was designed by a Canadian company called Radon Environmental.
It works by using a Low Voltage compressor to pump air down into the well to release the radon in the water.
It has had performance as good as 99%.  The design requires a system that does not airlock the well.

Granular activated carbon (GAC) systems are simple and less costly than aeration but often provide poor performance.  They require yearly or bi-yearly carbon replacement.
