Our paper “Models for predicting organic micropollutant breakthrough in carbon adsorbers based on water quality, adsorbate properties, and rapid small-scale column tests” received favorable reviews.
You are correct that a small portion of the flow will go up the pipe used to protect the motion of the string. But overall this is small compared with the area of the roughing filter. The biological sand filter also works to remove particulates not removed in the roughing filter step.
Since the water travels through the gaps between the river rocks rather than 'through the rocks itself'; i don't think this passage through pvc is a big deal. plus, the flow of water itself directly depends upon the rate of outflow which is not significant at all. That factor holds the water for long long enough in each phase of purification. Great Solution. Thanks for sharing.
The only thing I would perhaps add to this is additional 'storage' tanks in case the water head runs dry or a major maintenance is required.
Hello, can you tell me if it is necessary to have all four sections of the barrels if you are working with deep groundwater from a well (51 meters deep) that is supplying very clear water.? Even though it is clear, I would not assume it is free of contaminants. This is surrounded by Isan Thailand Farms where there is copious use of pesticides. Thank you for any advice. Best..
If there is not much sediment in the well water you could just use the biological sand filter for pathogen control and biochar adsorber for chemical control. Or biochar adsorber followed by silver-impregnated ceramic filtration or chlorination for disinfection. The gravel filter is mainly for water courses that contain particles and turbidity in excess of 10-20 NTU.
Often rainwater can be used without further treatment, if it is not contaminated by materials on the roof or in the storage cistern. As an additional safety factor, stored rainwater can be disinfected using chlorine, or treated using, for example, ceramic filters as a barrier against microbial contaminants that may reside in the storage vessel. Our partners at Caminos de Agua use ceramic filters for point-of-use household treatment of stored rainwater: https://www.caminosdeagua.org/en/ceramic-filter
Bit childish question can you send procedure how to make ceramic filter. As per my understanding by mixing cement,sand and gravel in mould we can make it.
It takes considerable experience with ceramics to get a consistent, effective filter product. Caminos de Agua has done extensive testing on their process over several years. https://www.caminosdeagua.org/en/ceramic-filter
I am getting hooked with your project and I am looking forward to realize it. Since it is not my area of expertise therefore I am doing a lot of readings before starting the experience. I have to mention that I am in a developing country in Africa where resources are very limited. I thank you for your great contribution to well being of human kind. Awesome, good luck in your future work.
I’ve just subscribed and looking forward to reading your blog. Until your book is published, is it possible to get the completed chapters as PDFs to save for offline access?
That's a good suggestion, Charlotte. Let me see if there is an easy way to do that. We've continued to edited back sections that appeared previously as works-in-progress on this site, so I will have to see about getting clean versions.
I think that it have some problems with the pre-filter. The water will go up without pass the pre-filter to the top it will go up via middle tube

Nice article.please guide simple approved method how to treat rain water obtained from RWH for drinking purpose?

Thank You So Much Mr. Kearns.Plz share your twitter link if possible.

Glad you are excited about the project! Feel free to post comments, questions, and suggestions as we go along.
