Answers to the most common questions we've encountered since 1994 

Question: Is it better having a radon aerator which provides 40 l/min than 20 l/min?

Answer :  A radon aerator shall always provide at least 20 l/min but never more than the well pump. A normal pump for a household rarely delivers more than app. 20 l/min, after pressure, height and loss of friction (at 2 bar pressure). A radon aerator that is "too large" in relation to your well pump creates unnecessary wear and tear to your radon aerator. 

Therefore, Radonett has 5 different models which can fit properly with your construction. 

However, make note that  40 l/min of water on the grass field coming out of a garden hose is not the same thing as 40 l/min in water taps in a house; that is where you want to have pressure in all your taps and that's where the torrent is minimized considerably.  The Radonett torrent is calculated at 2 bar pressure and has a working pressure of up to app.4.5 bar (1 bar = 1 kg). 

The lowest pressure Radonett provides over 50 liters per minute without extra pressure being applied(!) and app. 20 l/min at 2 bar with pressure.

Question: How do you calculate the degree of purification for various radon/Co2 aerators?

Answer :   It is relatively simple to build a radon aerator that provides a high degree of purification after a little tap volume and low pressure. 

However, observe that the water should be clean even if many people are showering at the same time. The pressure should be sufficient in  all of the house's taps. The degree of purification shall be calculated at a rate of 20 l/min with 2 bar pressure at a tap volume of 1000 liters. This norm is an EU standard assumed by Jonny Andersson Radonett/Sarholms Sverige.

This norm is demanded for a EPD noticed/approved radon aerator. The norm is being used because in the future, the radon aerator's measuring results will be based on similar conditions. Radonett är Europas only EPD approved radon aerator .

Question: How much noise does a radon aerator generate?

Answer : Radonett has a volume level of app. 56 dB, which meets the normal tone of conversation. NB that Radonett is only functioning when you are washing, showering, rinsing, etc.  It does not run the whole day.

Question: What does is cost to use a radon/Co2 aerator?

Answer :  Radonett A1UV has an operating cost (electricity filter UV lamp, etc.) of several hundred crowns per year! 

Question: Can I install a radon aerator myself?

Answer :  Installing a Radonett is much like the new installation of a wash machine (plus an exhaust pipe through the wall surface).

If you do this type of work at home, you can easily install a Radonett. A very complete installation instruction manual is included in the delivery.

Question: Is the guarantee still valid if you install the radon aerator yourself.

Answer :  Yes, for Radonett.

Question: Does a radon aerator remove more than just radon.

Answer :  Radonett removes radon gas, radon daughters, methane gas, sulphur hydrogen, carbon dioxide, aggressive carbonic acid, and increases a low pH. Flocks iron and manganese  through the aeration process. This includes bacterial purification of process air with UV light. Radonett can be completed with a special filter for removing uranium.

Radonett makes water good and wholesome with a clear and fresh taste.

Question: Can you use carbon filters to remove radon from water?

Answer : Yes, if the percentage isn't too high. Carbon filter tubes can provid a lower initial cost but, over time, they become expensive and troublesome because the filter pulps need to be changed regularly.

  All water must be put through filter pulps, not only drinking water (it is when the radon spreads from the shower and dishwater, etc. which is the most dangerous, not only the intake of radon-contaminated water). Thus, filter tubes must be dimensioned for  the entire household. Filter tubes should be disassembled and changed at the filter pulps regularly. 

Filter tubes must not be placed in the living quarters space without radiation protection. The filter pulp is radioactive and should be deposited at a specially assigned place and treated carefully. Also see STUK/tenawa rapporten, and  http://www.uni-mainz.de/~eswe/tenawa.htm  (about the risk of radiation damage, etc. caused by filter tubes).

Question: Do I know if the radon aerator is functioning even after many years or to I have to conduct a water test regularly?

Answer :  Water tests should always be taken after app. one week after installation in order to control whether the installer has installed the device properly.

Radonett radon aerators use only 1 pump (motor) for all of the radon aerator's functions.  If this motor should stop, the purification stops as well, but at the same time so does the water supply to the household because everything is connected to and using the same pump. If you have a machine with 2 or 3 motors, (fans, purification pump, pressure pump) and then the purification pump or the fan stops, non-purified water comes out into the household spickets through the pressure pump without anyone noticing it. With Radonett, you are not taking the chance that you receive non-purified water within the household because if the purification stops and thus, the entire water supply is put on hold.

Question: Can you purify the water right in the boring hole?

Answer :  Yes, this was proven over a decade ago. It takes a long time to purify water when you have tapped a certain quantity of water and the rest comes out partly non-purified. The water in the drill hole moves sideways while the pure water is transported out quickly forward through different drill holes. Thus, it can be difficult to predict the exact result. A drill hole with cold water has a greater sideways flow than a "warm hole".  Normally, the water contains iron and manganese because the remainders are returned to the drill hole and a part is sucked back through the pump in an eternal circulation.
