About to build my washout booth with filtration in a few weeks or so, I would like to share some thoughts and hope that others will share some ideas.


This is the filter I posted earlier elsewhere. It is a ceramic drip filter which I plan to use as the final filter in my washout filtration system.It costs US17 here and I hear there are US10 models available but I think is cost something around US$20 in the US.

Some videos on the Ceramic Drip Filter

Found an earlier post and reposting here with some edits on sizes of opening and prices)

Some ceramic filters incorporate nano-silver impregnated into a porous ceramic outer shell that can trap bacteria down to as low as .22 of a micron in particle size [1/100,000 of an inch]
....
Laboratories consider a filtering medium with an effective pore size of .01 micron to .45 micron to be bacteriologically sterile and .45 micron to 1.0 micron to be bacteriologically safe...

Bacteria range in size from 0.2 to 2 microns in width or diameter and from 1 to 10 microns in length for the nonspherical specie, so a 1-micron filter will remove most bacteria and cysts.

What if one uses a sediment filter(the towel in the video), series of pre-filter to prevent the final filter from clogging early, and a 0.2 micron ceramic filter at the end of the filtration system for a wash out booth?

As posted earlier, that ceramic drip filter is the one I plan to put at the end of my filtration system. I clarified with the dealer and was told that ours is a 0.2 micron filter but the one on the video has 0.5 micron. A brand new Korean Ceramic Drip Filter impregnated with silver cost about US20 here. A Taiwan made 0.9micron ceramic drip filter cost about $17 and a China made 0.9 micron ceramic drip filters cost under $10.

My plan is to use the newer filters to filter our drinking water then after every few months, move it to the washout booth/tank/bucket. I may add more filters to facilitate the draining.

These ceramic filters are very fragile and are often rinsed only for cleaning. But if necessary a soft sponge applied to the ceramic surface very gently can be done. Hard strokes may damage the filter. These filters can be used until the ceramic thins out due to washing or if it cracks.

Your sediment filters(cloth or any suitable fabric including old screen mesh) and pre-filters(finer fabrics or larger micron filters) should determine how long your ceramic filters clogs or needs cleaning.

A cheaper alternative

As I previously stated, I want to use that ceramic drop filter at the conclusion of my filtering system. I asked the dealer about it, and he said ours has a 0.2 micron filter, but the one in the video is 0.5 micron. A brand new silver-impregnated Korean Ceramic Drip Filter costs around US$20 here. A 0.9 micron ceramic drip filter manufactured in Taiwan costs around $17, whereas a 0.9 micron ceramic drip filter made in China costs less than $10.

My goal is to utilise the newer filters to filter our drinking water, then shift it to the washout booth/tank/bucket after a few months. To make draining easier, I may add extra filters. I'm also looking for the best faucet water filter.
