What is a dual media filter in water treatment process?
Dual media filter is a type of filter used to purify drinking water. It is used by water treatment companies. I want to know the advantages and disadvantages of using dual media filter.

Dual media refers to the number of filter materials in use. For example, the first stage of the filter might be one to catch the coarse particles such as a pleated fine mesh paper material. The second stage of the filter could be a finer mesh media or maybe a netted bag of carbon particles to remove smell or taste.
The advantage of course is efficiency of the filter and effectiveness. Different conditions dictate what media choice you make. The best method I have encountered is of course, a graduated mesh media, starting with a larger opening mesh, then stepping down to a smaller mesh and so on. The final stage of filtration would likely be one that removes smell or taste from the water. The bottom line in advantages is that the fewer number of passes through the filter, the better as long as you achieve a good end product.
