Reader question: Water treatment for drinking water in Thailand what should I pay attention to?
Dear readers,
We always buy bottled water for drinking water. Now my wife wants to buy a water purifier.
Now I'm no expert, but it seems that there are different versions and price ranges.
What should we pay attention to and what are your experiences?
Regards,
Benny
We have these at home
https://www.homepro.co.th/p/1117015
very satisfied. 1x per year new cartridge of ± 3000 thb
We (family of 2 people) buy the 20 liter bottles that are delivered to your home by 4 companies. 10 Baht for 20 litres. Friends of ours have a business like this. That is why we also know that it is spring water, drilled from a depth of 50 meters, so that no chemicals or pesticides are left in the water. Those companies regularly receive government inspections on the quality of their water and it sometimes happens that a company is temporarily out of circulation to clean or replace its pipes. This has been happening here for years, previously at 13 Baht, now due to the competition at 10 Baht/20 liters. We cook with it, use it as drinking water (daily 2 liters per person), our dogs quench their thirst with it. Our consumption is about 5 bottles per week, which amounts to 2.500 Baht on an annual basis. This is still cheaper than a 3.000 Baht annual cartridge. Then our tap water is another 1.500 Baht per year (120 Baht / month) for the shower, and the plants and the dishes.
With us, purchasing a water purifier is neither profitable nor interesting.
But every region has different prices and different quality spring water, so the choice is yours.
Good luck with your choice.
And there MUST be a UV system otherwise no permission.
UV kills algae and bacteria and removes odors
At least 200 Watt at a flow of 80 liters per minute.
Reverse osmosis system for home use but also with UV. His smaller systems do about 20 liters per hour. Enough for normal home. A stainless steel tank is included
Water purification or filter device?
We are two people and I bought a Camarcio Reverse Osmosis System about a year and a half ago. It consists of 5 filters, a pump, a tank and a tap. I installed it myself and bought it from Global House for less than 5000 Baht. The water that we get here is hard, but otherwise quite pure. Two weeks ago I changed the filters (actually should be more often) and I saw almost no discoloration, even though it was written that it would look rather dirty.
The water tastes fine.
I ordered the new filters from Lazada for 500 Baht and were also very easy to change, because they only fit in the right holder.
You can also buy filter systems with UV radiation, which also kills bacteria. We don't have that.
There are of course places where the water from the tap is less clean (we live in the countryside south of Hua Hin). You could have the water measured and a system built in based on that, but is that really necessary?
https://globalhouse.co.th/product/detail/8852381125320.html
This system works for us and we save around 500 baht per month on drinking water costs, journeys and also a lot of space. And of course less waste.
If you don't already have a water cooler that can hold those inverted bottles, then if you ever want to buy one, I would look into a system that you can connect your filtered water to. Then you have clean cold and hot water in one fell swoop and you never have to fill up new bottles and put them on that device. I do that every time and I can imagine that when I'm about ten years further, it will become increasingly difficult to place those bottles on there. Now I always fill them up with our filter water.
I also ordered a larger tank from Lazada. That is handy, because then you can use more water in one go (this in connection with our water cooler). Normally the supplied tank is sufficient.
I've been around for about ten years and have ensured that we (my wife is 20 years younger) nevertheless have a strong 6-day housekeeper and she does it effortlessly: put that large bottle on the water dispenser. And by the way, we use bottles for all our drinking water, so easy. We have a water purification system that has never been used before: reverse osmosis. But our bottled water costs are low, about 2000 Baht per year for 2 people and we are not economical with it.
UV also removes algae and odors. Mandatory for professional systems
Dear Rori, you have already written twice that UV removes the odors. That is not true. UV only kills bacteria and other living material. No more. It does not remove sediments and certainly no odors or tastes. The carbon filter does this at the end of the process.
You can use a UV filter that is then used before or after the filtering process. Then you can also kill bacteria. The lamp of this must be replaced at least once a year and also kept clean more often, otherwise the rays will not get through.
It depends on the area where you live. If there are a lot of bacteria in your water, a UV filter makes sense. If not, an RO filter alone is sufficient.
Numerous descriptions can be found on the internet (the best in English, because virtually no filter installations are used in the Netherlands). Google this: reverse osmosis vs ultra violet. Then you will learn a thing or two about the filters.
My humble opinion is that ROS is sufficient, but if you want to have 99,99% clean water, you must also use a UV filter. I am already satisfied with 99%, without UV.
When we still lived in Chiang Rai, my wife had a water shop, she didn't sell water but pumps, filters and everything that came with it. Reverse osmosis was also used to purify water.
Wells were only drilled when there was no water supply.
If there was tap water and that is not always good to drink, a storage tank of 5 cubic meters was installed and then a reverse osmosis installation.
This is how it looks in our new house in Thailand, even with some superfluous filters, because I wanted it so badly then (8 years ago).
But it has never been used, we drink bottled water and with such a very large bottle on the hot and cold water machine, it is so easy, no maintenance, no malfunctions, no extra electricity and that while (or because) we have the expertise in-house.
Outside we use well water or, if you prefer, ground water.
Just buy Water-to-Go filter bottles.
Even filter viruses from fresh water.
