RO does remove salt, its membrane will remove just about everthing, the battery manufacturers even said it is pure enough for battery water. I have one that makes water for my off-grid batteries.There has to be some kind of membrane that removes salt. Does an RO filter remove salt?
VOC's are an interesting group of contaminants and include some pretty nasty ones. They vaporize at a low temperature and usually give off a strong odor. They can give water a sweet taste, too. They include gasoline, benzene, paints and solvents. If you have any VOC's in your water source, you will want to use activated carbon to remove it. Granulated Activated Carbon will reduce the VOC's as well.howdy yall, i like this subject. im planning on building a biosand/slowsand filter. ive done quite a bit of research and aside from berkey and sawyer, which are not very cheap, not unaffordable, but not cheap, the biosand is my personal choice for purification. and its realitively affordable as well as not too difficult to make. it takes some time to get going, but once the beneficial bacteria get established in the very top layer of the sand it is supposed to filter out most if not all voc's (volitile organic compounds). please do your own research and dont take what im saying as absolute truth, i am by no means an expert. i just studied untill i was satisfied as to which rout i would follow. just my 2 pennies. good luck and be safe!

Absolutely. I have enough "parts" to make three... but not enough sand. Sand is easy to find but hard to move. I don't have a lot of room to store spare sand right now. Maybe I can make a HUGE sandbox for the kids? That will be my reserve!Most parts that are used are easily available now and it might be worth getting the parts to make one now and just have it available.
It is possible, but depending on scale all you are making is a strainer.is this possible and how can I make a filter like this using sand and random junk?
I would avoid doing that.... keep it simple (KISS principle).I would add the layers of Activated Charcoal and Dichotomous Earth between the Pea gravel and sand using an extra end cap with holes drilled like the "diffuser plate" and then a coffee filter on top of that to prevent the finer Dichotomous Earth to infiltrate the pea gravel.
Can't disagree with the KISS concept! But that is why I would add those two items to the filter.I would avoid doing that.... keep it simple (KISS principle)
The final product that comes out can have the last few (if any) pathogens killed with a little bleach. You can pour the water back and forth between two buckets to get the bleach out.
Nothing takes salt out, except for distillation.
