Grey Water Recycle: How Often Should a Sand Paper Filter Be Replaced? Grey Water Recycle: How Often Should a Sand Paper Filter Be Replaced?

If you have a grey water recycle system, you will probably want to use a sand paper filtering system. A sand paper filter is excellent for waste water recycling. Its cost is lower than most of the other filtering systems on the market and it is no problem to run. A sand paper filter system is easy and cheap to install. It is very effective since the sand paper is on the inside of the system. The granules from the sand paper help to clean the new water and clear out waste from it. When it comes to maintaining the sand paper filter system, there really is not that much to it at all. The only maintenance required is a basic cleaning and for you to change the sand paper. 

Cleaning and Changing Rapid Sand Paper Filters for Grey Water Recycling System

A rapid sand paper filter is the type of filter used the most in grey water systems. It has layers of coal and carbon above the sand. The first layer of this paper helps to remove organic compounds that help contribute to odor and taste. Sometimes particles that pass through one surface of the sand paper filter can get stuck or suspended in the second or third later and is trapped in the pores or stick to the sand particles. The filter is created for this purpose so that all particles will not be able to stick to the top layer. This can result in having to change the filter every week or so because it would stay clogged. Using a rapid sand filter, you will only have to change it every three or four months at the most. The reason this filter does not have to be changed often is that it can be cleaned when water passes through it and back flushed. This removes any of the particles that have become stuck or embedded throughout the sand paper filter.

Cleaning and Changing Slow Sand Filters for Grey Water Recycling System

A slow sand paper filter passes water passed through it very slow and is used where there is enough land or space. These filters are made using the coarsest layers of sand, layers of gravel and fine sand as the top layer. If a slow filter is as effective as should be, it can be used for many weeks if it has been pre-treated with nutrient levels that are low. Slow sand filter are not able to be back flushed like the rapid systems. When the top layer is clogged with particles, it is scraped off. A slow sand filter will need to be changed at least ever 11/2 to 2 months to work properly.
