According to some embodiments, a vent filter for a waste tank system is provided having a housing which eliminates or reduces the amount of bypass of odorous air moving through the vent system and precludes the odorous air from escaping without passing through filtering material. The housing includes a region wherein the cross-sectional area is reduced, inhibiting bypass of odorous gas past the filtering material.

System for a ductless fume hood (100) comprising a ductless fume hood (100) including a hood enclosure; two or more detectors comprising a photo-ionization detector (PID) sensor and at least one of a metal oxide detector (MOX) or an acid array sensor; the system also comprising a motor (102) which draws an effluent stream (C) of contaminated air through the hood enclosure; at least one chemical removal filter (106) for egress at an exhaust stack (118) and a processor operatively coupled a control panel (120) and configured to determine, in response to a user selection of at least one chemical species from a plurality of chemical species included in a chemical database, the at least one chemical removal filter capable of removing the selected chemical species from the effluent stream of contaminated air.
摘要:
The invention relates to processes for reducing ammonia loss and odor from organic material or waste to the atmosphere. A plasma generator is applied to upgrade organic waste and manure with a mixture of acidic nitrates and nitrites. The present invention also relates to an acidic nitrate solution, suitable for reducing ammonia loss and odor from organic material or waste to the atmosphere, and a process for producing such an acidic nitrate solution. The invention further comprises plants for reducing ammonia loss and odor from organic material or waste to the atmosphere.
摘要:
The present invention concerns a composite oxide based on cerium, oxide, silicon oxide and titanium oxide. The present invention also concerns a process to obtain these composites, a catalytic system comprising said composite oxides and their use for the treatment of exhaust gases from internal combustion, notably by bringing into contact exhaust gases from internal combustion engines with these catalytic systems.
