Water Softners

[CDNinKS]

Has anyone had any experience with this company:

I'm particularly interested in the water treatment they are showing. The water where we are building is very hard and I suspect I will have to install a softener. I have had the traditional softeners in the past that use the salt bath method and they work fine, but need to buy salt constantly. I have been quoted between 20,000 and 29,000 B for one of those.

This company is advertising a system that uses (I think) Zeolite to remove the hardness. From what I understand this is the same material used in swimming pool filters as an alternative to sand.

Anyone with any first hand knowledge?

I too am interested in this product and eager to hear from some users.

Theas are filters not softeners. I have seen this companys filters and can state they will not work for hard water softening. I have tried ion exchange resin but the drawback is the constant need for salt. I used a company from Cha-am who claimed to be able to offer a system . I had one fitted, a large stainless fiter filled with resin (40k). This appeared initially to work. The company promised ( for a fee) that he would take care of the regeneration of the resin and servicing . He came once after being reminded when we noticed the hardness returning. Again worked for around a month. We tried to get them back again but they keep making appointments and failing to appear.We have brine washed the system ourselves and have worked out we will require 30kg+ salt every three weeks to maintain the system.The problem is not the salt ( cheap) but the time it takes to service. I have also had experience of a automatic regeneration system ( 150k Baht) . This was supposed to be designed for several houses. It did not work and has since been connected to only one house who I believe is happy with it.
I would along with many others living with hard water to find a cost effective solution.

Zeolite is used in filtration systems, it is not a softener, as poosmate has written. The other drawback with resin bed softeners, in addition to the salt, is the amount of water that goes to waste as brine.

There is a way to do it electronically, but the keywords are: "cost effective". A couple of the systems in the link have been installed in Hua Hin, as part of the estate water supply from underground. The systems do work, with the proviso that the effect on the water only lasts up to about five days. So if you are using a storage buffer tank (as you should be doing), then it is questionable if it is effective. The cost of the units make it prohibitive for an individual house, and if you could get all the houses on an estate connected to the system it would have to bypass your storage tank, and depend on a reliable supply from the bore.

On a commercial scale there are several golf clubs in Thailand using these systems with good results. The last time I had any contact with the agent, they did not have small, household, types available.

Thanks for the info......that was what I suspected, there is no magic bullet.

Looks like the resin/salt method or nothing I guess.
