Which water purifier system

[CNXexpat]

Our village uses groundwater but the water doesn´t look clean. Also our water tank is under the ground what is difficult to maintain. So we are thinking about to buy our own water cleaning system and a tank on the ground. Any recommendations which systems and brands are good? Also for water tanks I see prices between 5,000 and 30,000 Baht for the same size. Are there independent tests of different systems and tanks?

The best testing comes from the 1000's of users own experience. 

My first choice of pump is Grundfos, others will tell to Mitsubishi, Hitachi, etc, it comes down to price and local service availability. 

For tank I used fibreglass and happy with it, but don't really have any preference.

Thank you. But the pump is not the problem. Interesting is the water cleaning system. What is necessary, which brand is good, etc.

Green color or just a bit muddy?  If the latter, you could put something like a sand filter in front of the tank.  There really isn't much maintenance for a storage tank.  In your case, there could be a build up of sediment on the bottom - maybe get the cesspit guys to suck it out?

The fist thing to do is get the water tested. 

 

If you fill a clear bottle and leave it undisturbed for a day or two does the water clear up? 

 

How does it smell? 

 

Are you filtering it to drink or just to bathe and whatnot?

First thing is to decide what the water will be used for, this will govern what treatment is required, there is a major difference between drinking water and watering the garden, showering or washing the dishes. A water analysis is a good place to start depending on usage needs. 

As bankruasteve has said, if it's just a bit cloudy /muddy, a pre sand filter with increased tank size giving more settling time maybe sufficient. 

If drinking water,  3 stage filter with UV is the way to go.

A very little bit muddy.

The smell is ok but it´s not 100% clear.

I only want it for showering, washing clothes and dishes and cooking. For drinking I only use mineral water because the so called drinking water is completely dead.

Guess you are already using the water for the reasons set out, if you don't have any problems currently other than a bit muddy I would opt for sand filtration or a larger tank or a couple of tanks allowing more settling time. 

 

If using sand filter, the local builders sand is not the best option as it too rounded in shape, clogs quicker and doesn't filter  well, you need either commercial filter sand or "sharp" sand - if you can locate it. 

Also look at treating your own drinking water, I have been doing this for more than 10 years in our current house without any problems other than filter cartridge changes and 1 new UV lamp that latest about 9 years from new.

Are you able to draw water from the source before your underground tank? 

 

If so, does it look the same as the water you draw from the tank? 

 

If it does, there is nothing wrong with the tank, an you should use it in conjunction with the new tank rather than replacing it.

 

You should put your primary filter between the old tank and the new tank, and a secondary filter after the new tank. 

 

With filters, bigger is generally better. I like Pentek “Big Clear” filters, 50 micron primary, 5 micron secondary. 

 

The most important thing is that you are able to get resonantly priced replacement elements. 

 

I like the clear housings because I can see how dirty the filters are getting.

Using the existing tank as a primary with a new secondary tank with the filters as you described is a great option.
