Filter media for efficient water treatment and energy-efficient operation

EnviroProcess offers a wide range of filter media for water treatment - from classic filter sand to modern glass beads, activated carbon and specialised media for powder filters. With the right filter media, you can improve water quality, energy consumption and the lifetime of your plant.

Filter media - optimised filtration for all needs

EnviroProcess offers a wide range of filter media, tested and carefully selected and adapted to fulfil different filter types and conditions. The choice of filter media is crucial for the efficient use of the plant's treatment capacity. EnviroProcess contributes with its expertise in the field and high-quality filter media that both improve water quality and optimise energy consumption.

Pressurised sand filters and filter sand

For pressurised sand filters, it is important to choose a filter media with low pressure drop and easy cleaning. Filter sand, or silica sand, is a popular solution. Grain size and distribution are critical factors - too fine sand can block quickly while too coarse sand risks filter breakthrough. EnviroProcess offers sand with optimal grain distribution, meeting the requirements of SS-EN 12904, for high capacity and efficient flushing.

Activated carbon and hydroanthracite

Activated carbon is made from various materials such as wood and coconut shells and has a high adsorption capacity, particularly effective in reducing organic pollutants and THMs. Stone carbon is best for larger molecules while coconut carbon is ideal for smaller pollutants. Hydroanthracite-H, made from lignite, is often used in multi-layer filters and combines low weight with high dirt-holding capacity.

Glass beads as an alternative to sand

Glass beads offer a higher permeability than sand, leading to lower pressure drop and reduced energy consumption. These polished glass beads are free of impurities and provide efficient filtration with rapid expansion during backwashing, minimising water consumption.

Powder filters: Diatomite and Perlite

Powder filters, using filter media such as diatomite or perlite, are compact and have low flushing water consumption. Diatomite, with its irregular surfaces, offers sharp filtration properties but is harmful if inhaled. Perlite, safer from a health point of view, requires careful selection of quality and grain size for effective filtration.
