摘要： The present invention relates to a filter for purification of water. An object of the present invention is to provide a filter for purification of liquids which achieves at least 2 log reductions of bacteria, viruses or cysts. It is a further object of the present invention to provide a filter for purification of liquids which provides high flow rates in gravity fed water purification systems. The present inventors have surprisingly found that a filter comprising a fibrous support composed of fibres and a matrix of polymer with copper impregnated therein characterised in that the matrix of polymer is superimposed on the surface of the fibres, not only provides reduction of viruses from a liquid to be purified at low pressure drops but also retains high flow rates. It was further found that the copper leach from the filter is within limits.

摘要： Process for removing hydrocarbons from a body of water wherein the hydrocarbons are separated from the aqueous phase by selective permeation through a sintered porous filter surface-treated with at least one hydrophobic product, so as to collect the hydrocarbons and remove them from the water without using additional chemical products or products capable of absorbing the hydrocarbons. This allows the body of water to be remediated and at the same time recover the hydrocarbons spilled in a clean and substantially continuous manner. The filter preferably consists of a sintered inorganic material, such as for example a metallic material, a vitreous material, a ceramic material.

摘要： A method and a system for separation of impurities, especially nutrients, from wastewater. In the present method, water having a low nutrient content is brought to flow through at least two zones, which zones are arranged in the direction of the water flow in a desired order, and which comprise, independently of each other, material which is intended to separate impurities and which is selected from a group that is comprised of living willows with roots, willow chips, carbonised parts of willow, or a mixture of willow chips and carbonised parts of willow, in which case at least two zones comprise materials that differ from each other. This solution can be used to purify impure, typically nutrient-rich wastewaters, such as household and municipal wastewaters, as well as farming and agricultural leachates, for example surface water and storm water originating in fields, barns, pig houses, sheep barns, henhouses, stables and fur farms, and to recover nutrients

摘要： A filter and filter material for providing or treating potable water is provided. The filter includes a housing having an inlet and an outlet, a filter material disposed within the housing, the filter material formed at least in part from a mixture of a plurality of mesoporous and microporous activated carbon particles. Preferably, at least some of the mesoporous activated carbon filter particles are coated with a cationic polymer, and even more preferably, at least some of the particles are coated with a cationic polymer and silver or a silver containing material.
