Water Filter to keep dirt out of tank

[brianks]

Looking for a simple water filter that will keep the dirt out of the tank only. Don't want soft water unit or something fancy. Have Master M3 filter but it is too fine and clogged quickly and can't clean so disconnected. Know there are two filter units at Home Pro one from Clarte and another one that look and seem to work similar. Do they work? Went to Pure and they were useless. Couldn't translate their water analysis report for me so I gave up and walked out. Anyone have or know of something simple that does filter the dirt out?

We have this one, but it is between the tank and the house to keep the dirt out of the home system. I really haven't heard of filters installed before the tank.

brianks,
you are doing things right by also filtering your water BEFORE it gets to your tank as this means better quality water to store and less treatment out from the tank. What is the source of the water and have you any idea of what it's quality may be like before tanking it?

[brianks]

WOW! Thanks guys. Where do you find the Mazuma filter?
deepee: Water quality is not very good here out on Soi 88 over the hill. Lots of white stuff in water and since I could not read Thai report from Pure don't know what is really in it. All I know is that I get a good amount of sediment build up in the bottom of my tanks and water leaves the white spots on plants when it dries.

I would think you would need a pump (also before the tank) as water pressure here is not usually adequate to push it through a filter. That's why ours is after the tank and the pump. It requires a high level of water pressure to filter the water and the filter even has a pressure gauge and relief valve. Are you planning to have or do you have two pressure pumps before and after the tank?

I'm not sure where our filter came from as it was installed by the builder as part of the contract, but I've seen them (Mazuma) at HomePro a while ago.

I have a pressure pump after the tank but none before it. We rely on the varriable pressure of the system (when it is on and delivering water--usually now at night only) to put it into the tank but have to say had to remove the M3 filter cartridge when put in another tank as water just would not push through it any more.

Have seen the Mazuma filters at Home Pro and a similar one by Clarte. Does yours work? How often do you have to change the filter?

I have been using it for years with the same filter and it works great. I just backwash the filter every month as instructed on the tank and a lot of muddy water comes out of a valve on the filter. The water in the house is always clean and clear.

What type of filter do you have?
We have a Mazuma S-27 BEFORE the tank with resin filter to filter the calcium. But as we have a flow of about 100 m3 per month we should put salt in it very often, which is quite cumbersome. So it is not much use. Our only pump is AFTER the tank.
The water in the house looks always clean because you don't see the calcium, but we have to treat our fittings wirh vinegar quite often.

Hope you aren't drinking this water. Have known some to do so and suffer kidney stones as a result.

I installed a Clarte model with all the bells and whistles, thinking I could convert bore-hole water into drinking or bath water. Unfortunately it's output is too slow and noisy for the latter and the output PH was far too low for the former. Around 5. Despite all the UV, RO and filtration, my test meter indicated there were still particulates in the water and the filter clogs up rapidly.

I believe it's okay for running municipal water through it.

my question refered to what is inside the filter:
ActivateCarbon
CationResin
Anthracite
Manganese

with carbon you get black output after backwash, with resin you get a rusty red one and you have to regenerate it with salt all 2-3 weeks.

Today I ran across a Fujika modular filter surprising at Power Buy that might do the job. Multi stage system you can bolt up to 5 units together to filter and process the water. Each unit does something different. First one might do what I want as it only filters out sand. Anyone know anything about the Fujika unit?

I had a quick look and I think part of the problem is we are discussing 2 issues (ie filter and treatment/conditioning)

I think it's essential to filtre out large sediments first (eg sand) before getting to any second stage if your water is prone to this as your second stage expensive medium life span would soon be reduced.

Like you I can't seem to see any large cheap replaceable units sediment filter which if placed before the tank need to be resonabley course so not to impede water pressure too much.

The second stage treatment/conditioning depending on your requirements could be just a simple Activated Carbon and/or aditional filter medium to remove other soluables

I found the english link to these M5 and M7 units which are also recommended to be installed before the tank http://www.masterpure.com/id20.html and as noted above on other units these also need backwashing with Brine, it think they cost in the range of 15-20K. It seems this arrangement is preferable as the contact period in the filter is longer than having it installed after the pump, but providing you have 2 large storage tanks a slow feed should not be a problem.

There was also another link I found but could not get the pages to download properly maybe you will have better luck http://www.iwater.co.th/water-treatment-en.html

I also found a nice picture of someone who obviously did not get his chemstry set for his 12th birthday using Mazuma or simialar

Of course trying to get down to drinking water quality can increase the requirements drastically along with the quality of your town or well supply.

I had a nice surprise, my builder not only drilled his own well he added these filters, so most of my problems are solved and just need small local ones near my tanks
