摘要： The present invention discloses a purification method for purifying contaminated water, comprising at least one biological purification path as well as a filtration purification path, wherein the filtration purification path is operated at least partially in parallel to the biological purification path with a partial flow which is removed from the biological purification path. The purification method according to the invention can be used as, preferably last, stage of a purification process in a wastewater treatment plant prior to introducing the purified water into a river, lake or the ocean.

摘要： An ambient air purification device has a filter device arranged in a filter receiving region of its housing. The filter device has a main filter element and a prefilter element, each having a circumferential frame device. A clamping force generating device is provided in the housing to exert an axial clamping force on the frame device of the main filter element resting, when mounted, at the frame device of the prefilter element. The clamping force is transmitted to the frame device of the prefilter element and presses the latter seal-tightly via a seal against a circumferential contact shoulder of the filter receiving region to seal the filter device in the filter receiving region. The frame device of the main filter element is sealed indirectly by the frame device of the prefilter element in relation to the housing and has no seal location of its own in relation to the housing.

摘要： The present disclosure relates to an acid-base polymer blend membrane comprising at least one first polymer exhibiting acidic groups (A) and at least one second polymer exhibiting basic groups (B), wherein the molar ratio of acidic groups A / basic groups B in the acid-base polymer blend membrane is at least 1 / 0.25. Furthermore, the present disclosure relates to a cell membrane comprising a support structure and an acid-base polymer blend membrane, wherein the acid-base polymer blend membrane is impregnated on the support structure. Said cell membrane can be used in an electrodialysis cell, in a fuel cell, in a PEM electrolyzer, or in a redox flow battery, preferably in a redox flow battery.

摘要： A computer implemented system and process of analyzing real-time measurements of a one or more air quality sensors to provide an calculated estimate of airborne virus infection and air quality evaluation from current air quality measurements, advise those at risk, advise responsible parties of recommended actions to take, and in some embodiments take direct action in communication of instructions to air filtration and treatment equipment and HVAC systems to improve outside air flow, increase filtration, treat contaminated air and reduce humidity and reduce the risk of airborne virus transmission. Sensor data, calculated airborne infection risk, air quality, warnings and reports are created and distributed to network connected devices.

摘要： In a purification method for purifying contaminated water, the contaminated water contained in a purification tank is filtered by a membrane module disposed in the purification tank. An adsorption agent with powdered activated carbon is added to the purification tank at a raw side of the membrane module. The membrane module is aerated by inflow of air from below. The steps of filtering, adding, and aerating are carried out in parallel and/or sequentially. The purification method is used as a stage of a purification process of a wastewater treatment plant prior to introducing the water purified by the purification method into a river, lake or the ocean.

摘要： The invention refers to a deformable filter element comprising a flexible side element to seal pleats of its filter medium. An end section of the side element is bent over fold edges. The end section and the fold edges are secured to one another. The end section and a main section of the side element, which main section is typically arranged perpendicular to the fold edges, are neither parallel nor perpendicular to each other.

摘要： A bio-functional air filter medium is provided with a at least one particle filtration layer that retains particles and at least one bio-functional carrier coated with or having embedded therein antimicrobial, anti-viral and anti-allergenic materials. An air filter element having the bio-functional air filter medium is also disclosed. The bio-functional air filter medium is adapted to bind and capture allergens and block metabolism of bacteria, and provide anti-viral activity to effectively inhibit/deactivate viruses, all while filtering air in high flow, low pressure drop residential, HVAC or air purifier applications.

摘要： A replaceable air filter element has a multilayer filter medium panel configured for mounting on a reusable exoskeleton support frame. The exoskeleton support frame is installable on a flow face of the filter medium panel and is provided with U-shaped locking members configured to detachably engage with and mount the filter medium panel. The exoskeleton support frame is configured to be reused such that only the filter medium panel is replaced, thereby reducing the environmental waste and making for a “green” eco-friendly air filter element.
