Efficient, flexible and economical – meltblown technology for high-performance filtration
Almost 500,000 tons of nonwovens are currently used annually in the production of filters, which corresponds to approximately 10% of current worldwide industrial nonwovens manufactured. Here, the filter market is split into two areas: air and liquid filtration. While in excess of 170,000 tons of nonwovens were manufactured for gas/air filters in 2015, the volume for liquid filters was almost double at around 295,000 tons.
Depending on the specific application, the demands on filters are extremely high. To this end, high-efficiency particulate air filters for clean rooms must, for example, filter < 1µm particles from the air with virtually 100% efficiency. Filters must achieve their separation performance with the lowest possible pressure drop – in other words, filter resistance. Pressure drop is one of the most important quality features of filters: the lower the pressure drop, the more energy efficient the filter of the corresponding filter class is. A good example is vacuum cleaner filters. The class in the case of vacuum cleaners depends on the energy consumption, which is also influenced by the vacuum cleaner filter. If the filter is too dense, the vacuum cleaner draws more electricity and the energy consumption increases.

Solid-liquid separation technology for removing contaminant fines
By Barry A. Perlmutter, President & Managing Director, BHS-Sonthofen Inc.
Treating water for environmental and process benefits is becoming more important in the oil and gas, energy, bioenergy, biochemical and chemical industries. As these operations are looking to become more cost efficient, water usage is being investigated. One critical aspect of these processes is the solid-liquid separation technology that is used to keep the water free of solid contaminant fines.
