A filter device, in particular for fluids polluted with admixtures of water, such as diesel oil, includes a filter housing () having a fluid inlet (), a fluid outlet () and a filter element (). During the filtering process, the fluid can flow through the filter medium () of the filter element from the unfiltered side () to the filtered side () of the filter medium and into its inner filter cavity (). On at least one side of the filter medium (), a water-separating system () has a separating region () for separated water. The water separating system is connected via at least one water opening () that is open toward the separating region () to a water collecting chamber (). The filter element () has a passage () forming a fluid connection to the inner filter cavity () and can be connected to an element receptacle () of the filter housing (). A fluid-conveying system () forms fluid paths separated from each other. The first fluid path () leads from the fluid inlet () of the housing () to the unfiltered side () of the filter element (). The second fluid path () connects the respective water opening () to the water collecting chamber ().

Filter device and filter element provided therefor

A filter device, in particular for fluids contaminated with water admixtures, such as diesel oil, has a filter housing () holding at least one filter element (). The filter medium of the filter element separates an untreated side () from a treated side () during the filtration process in the filter housing (). A water collecting unit () is provided and holds separated water on the untreated side. Water separated on the untreated side () also reaches the collecting unit (). Mutually separated collecting chambers () are present in the collecting unit () for the water discharged at the treated side () and at the untreated side ().

Filter device

A device () for a fuel filter system () separates water from the fuel. The water takes on a property enhancing the separation by the device () by the action of a medium ().

Device for a fuel filter system

A filter device purifies fluids, especially fuels contaminated with organic substances. Hydroxyl radicals are formed from water molecules contained in the fluids by a separating device (). The hydroxyl radicals oxidize the impurities, especially organic substances, as much as possible and convert them into compounds such as CO.

Filter device for purifying fluids

A filter has first and second filter media (). The filter media define a flow space () between them receiving a device () for separation and flow guidance and dividing the flow space such that a functional space () is disposed adjacent to the first or the second filter medium. The first filter medium () defines a hollow space () toward the outside, and the second filter medium () defines a hollow space () toward the inside. Each of the hollow spaces () can be connected to at least one fluid duct (). The flow space () including the two functional spaces () can be connected to at least one further fluid duct () that is separated in a fluid-tight manner from the other fluid ducts ().

Filter

The invention relates to a device for purifying water contaminated with organic substances, which is drained or collected from filters, especially fuel filters or elements of a fuel system. Hydroxyl radicals are formed from the water by means of a separating device where the hydroxyl radicals oxidize the impurities, especially organic substances, as much as possible, and convert them into compounds such as CO.
