RE: Water! A Video On Purification & Preparedness On The Homestead. I Use My Sawyer Life Straw For 1st Time With Water From Our Dam & Discuss Water Independence For Plants, Animals & Us!
What volume can you put through one of those before it needs replacing?
The colour is probably tannins from plant matter in the dam, which should be harmless but may affect the taste. If you were doing it on a larger scale, you could get some activated charcoal and mix in the the water before one of the filtration steps. Those filters would have some charcoal in them, but evidently not enough to completely clarify the water.
Have you heard of biosand filters at all? They are a low-tech solution that works very well at purifying water and you could build one with higher throughput than the life straw.
Hi @brendio. These little filters are rated at 100,000 gallons. Great thinking with the tannins, I've seen "stained" water from rain water tanks too come to think of it and that was perfectly fine to drink.
Great tip with the charcoal. Haven't heard of biosand filters I'll have to check out out.
Thanks so much for your detailed additions & sorry for the late reply.
That's a lot longer lasting than I expected for such a small filter. I wouldn't think the Britta filters don't last that long.
It's impressive isnt it. Not sure on the britas. They have that silly timer thing build into the jug which is a time based replacement indicator rather than a volume one. It's probably a conservative measurement in order to sell more filters. Weve keep them going longer than we probably should. It's hard to say.
