World best filter material for purification of drinking

When algal blooms put the sand filters under pressure, Thames Water started its own in-house research into new filter materials. Not only did the effort cure the constraint, the use of new filter materials has saved millions in investments.

Fast Cleaning

To purify water with sand takes a long time. Besides requiring filters lot of maintenance and major resources in connection with cleaning. More than a dozen different materials, including sand, broken glass, sand / anthracite and Filtralite Mono-Multi were tested. Finally the choice fell on Filtralite Mono-Multi. It seems as if Filtralite has an additional filtration dimension, which can be explained with the open structure of the material. This is why we have already built about 37 filters with Filtralite, he says.
