Parallel Filters

Placing filters "in parallel" can will increase output, but costs more to implement.

Everyone agrees that water is a must-have essential at the top of the list for survival preparations. Consequently, there are a lot of products on the market for cleaning up contaminated water to make it fit for human consumption. Here’s a quick look at the advantages of ceramic cartridges versus other filter types and discussion of a few key issues.

What is a ceramic water filter? 

The ceramic filter consists of a porous ceramic shell and usually is sold as a sealed cartridge that contains some additional water purification media. A picture of a dome-shaped filter is shown here, but they can be manufactured in various shapes and sizes. The outer shell of the ceramic cartridge filters out bacteria using sub-micron sized pore openings. (A micron is a millionth of a meter). In addition, many chemicals can be filtered out using “broad spectrum” activated carbon inside the shell. Specialized filters to remove particular chemicals such as fluoride or arsenic can also be manufactured by using other media in place of the carbon.

What are the advantages of these filters? 

Some popular types of filters just use small pore openings to strain out bacteria but do nothing to treat the water for pesticides, fertilizers or petroleum-based products that may be present in water from lakes or rivers. Other types of water filters will just use activated carbon for the chemicals but not have small enough filter pores to eliminate bacteria.

They also have a system that does not require stacked buckets. It is a hanging bag that rolls up very compact and is great for hiking and camping: http://www.homespunenvironmental.com/Bag_Water_Filter_p/tk-1001.htm

Great article for saving on ceramic systems. A Berkey is nice, if you can afford it, but clean buckets with the kits work fine.
