Canister Water Filtration

[JonnieB]

i am setting-up a filtration system for a home i am buying in east pattaya. the house is in a mooban at the end of soi nungplabwan/patanakarn and has city water supply. the standard is "clean" water but not "potable" water. currently, the city water goes into an outside ss holding tank. from there, it is pumped into the house. my plan is to put a mini-canister type particle filter to strain out sand and dirt, and then after that, one of the tall metal free-standing mizuno canister filters filled with half-manganese and half charcoal mix.

should such a system give me the water i seek?

also, does it make a difference if i place the filters before the water enters and stores in the ss holding tank or after it?

also, what does the manganese do/filter out? i know charcoal is mainly for smell but i don't know what the manganese is for.

also, if i wanted to make the water potable, would a small canister ceramic filter as a third filter at the end of the filter train do the trick?

The manganese filter removes dissolved iron which can cause staining on washing and bathroom fittings.

The activated charcoal absorbs all sorts of stuff and makes the water taste nice (some may not agree with the second statement).

Put a coarse particulate filter on the inlet to your tank to stop build up of grit in the bottom.

We have a 3 stage resin/carbon/ceramic filter with a UV zapper, it only covers the kitchen taps though (for cooking and drinking) you may want to cover the bathroom sink too, for teeth cleaning.

Mains supply water is clean enough for bathing and the washing machine, we don't have a problem with dissolved iron.

Most of these filters have a fairly slow flow rate so you probably need to fit a filter to each outlet.

If you filter all the water comming out of your tank you will need to have a very high capacity filter and a lot of the filtering would probably be wasted as most of the water will be used for showers, toilets and washing that probably dont need filtered water.

To filter the water going in to the tank would also need a high capacity filter and if you have problems with dead rats, pigeons, geccos or other contaminants in your tank this filtering would be wasted.

Good thought

That's why I suggested a coarse inlet filter (one of the cotton units will do nicely and have a decent flow rate), just to stop the rocks.

I'm assuming his SS tank has a decent lid to keep out rats, snakes, gekkos etc.

We have a fibreglass filter on the input to the tank which takes out the majority of the gunge, sand etc.

The tank is stainless and with lid, which needs to be kept shut.

If you filter after the tank then you have flow capacity problems and a dirty tank!!

We use the tank water for all purposes except drinking.

For drinking we have one of the resin + charcoal + ceramic filters to fill the large water bottles for the cooler. Slow, but not a big deal. The ceramic filter needs a scrub every so often, when the flow gets too slow.

This set up has worked for me and my Thai wife for the last 5 years or so.

thank you for the suggestions. yes, i have a standard ss tank w/lid. i don't think dead organic matter will be much of a problem. however, in past places i have rented and also had ss water holding tanks (w/o any type of filter systems), i have noticed a large build-up of sediments (dirt) at the bottom of the tank (cleaned by opening the bottom spout and draining the tank).

the suggestion to put the coarse particulate filter BEFORE the ss tank is a good one. the one i have bought is a Clarte canister that i think has a 30 micron replaceable filter cartridge. this is just to keep the dirt and sand out of the tank and the follow-on in-house water appliances/faucets. i assume flow capacity would not be an issue as the house water will be drawn from the tank.

i assume the free-standing large canister filter with the manganese/charcoal filtration would best go after the ss tank.

my system is not to make potable water. i have decided against adding a 3rd ceramic filter. drinking and brushing water i buy bottled water.

What kind of flow can this canister take? We have to pump our water up to our tank and have a problem with brownish water. We are looking for something that we can attach before it reaches the tank but would it slow the pump down?

i will check the specs on the canister and post the info. it is pretty large for a non-free standing canister type filter...about 1.5 feet tall and 6 inches across.

Here are the specs:

clarte, model WP16P

water flow: 40 GPA (gallons per minute)

Filter: 5 microns

water pressure: 15-100 PSI
