LIQUID FILTRATION MEDIA

In mining, in the food industry, in water treatment—liquid filters are used in a multitude of applications. Given the increasing shortage of water, they continue to gain in importance.

The specific requirements placed on the filters in the respective uses are just as diverse as the applications themselves. Separating contaminants ranging from pebbles to grains of sand to microscopic particles, the filter has to be optimally adjusted to the specific particle size.

Filter media are the heart of any filtration plant. They determine which particle size can be deposited and whether the filter is able to achieve the required efficiency. These filter media therefore have to flexibly adapt to the specific requirements of the respective application. In some applications they have to be particularly thin and robust to be able to withstand pressure affecting them during filtration.

In other applications they are required to be bulky and particularly resistant to heat in order to reliably separate contaminants even from heated fluids. And where one of these alternatives is not enough, specific Sandler nonwovens combine several properties if required. The filter media of the sawaloom® and sawascreen® product series will win you over!

Particularly in solid-liquid filtration it is vital for the utilised materials to be single-polymer. For example in the food industry, materials containing chemical additives are not employed. This requirement is consistent with Sandler’s philosophy of producing single-polymer filter media without chemical binders, making these synthetic nonwovens free from toxicological risk.
