Filter water as rolling it in a barrel

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of a water filtration system designed to operate within a rolling barrel. The proposed system includes four panels with activated carbon and a mesh filter, aiming to filter water while the barrel is rolled for a duration of two hours. Participants explore the effectiveness and mechanics of this concept.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions the effectiveness of an "agitation type" filter, suggesting that traditional filters rely on fluid flowing through them to ensure contaminants are captured upstream.
  • Other participants reference existing filtration systems, such as the SafeSipp, which utilize different mechanisms including pre-filters and activated carbon, indicating that the proposed method may differ significantly from established designs.
  • There is a suggestion that the proposed design may not effectively filter water due to the nature of how filters typically function.

Areas of Agreement / Disagreement

Participants exhibit differing views on the effectiveness of the proposed filtration method, with some expressing skepticism about its feasibility while others reference similar systems that employ different filtering techniques. The discussion remains unresolved regarding the practicality of the rolling barrel concept.

Contextual Notes

Participants have not reached a consensus on the assumptions regarding the filtration effectiveness of the proposed design, and there are unresolved questions about the mechanics of water flow and filtration in this context.

Hi,

I need some help to verify whether this is possible or not.
I am working on a project that still in early phase of development. The idea is to create a water filter system to in a barrel as rolling it. Basically the barrel will contain 4 panels placed inside the barrel creating a shape of (+) sign in the barrel. The panels will contain activated carbon to filter the water and a mesh of 1mm holes. Let's say the barrel can carry 20gal of water. Is it possible to filter the water by rolling it for a 2 hrs duration using this concept? If not what would you suggest?
Note that there will be a gap right in the middle of the 4 panels. So they are not connected.

Typically filters are used in such a way that the fluid flows through the filter. This helps ensure anything caught by the filter stays upstream and doesn't pass through with the water. I'm not sure that an "agitation type" filter would be as effective.

This application is different. It utilizes a coarse mesh pre-filter when water is poured in the tank, chlorinated tablets, and an activated carbon filter that the water passes through when it is drained from the tank.
