Abstract: A green process and system are disclosed for utilizing a biomass filter aid in the filtration of a bio-oil. The process comprises filtering a bio-oil containing residual solids from a conversion reaction in the presence of the biomass filter aid to produce a filtered bio-oil. The biomass filter aid facilitates efficient removal of residual solids from the bio-oil. The spent biomass filter aid containing the residual solids may be recycled as a conversion feedstock or used as a combustion heat source in the biomass conversion system.

Abstract: A method and device is provided for collecting filterable material to perform assays on a filtration apparatus by applying negative-pressure to the inlet chamber of the filtration apparatus which is independent of negative or positive pressure applied to its fluid path. The negative-pressure applied to the inlet chamber serves to actively aspirate fluid and promote flow into the inlet chamber via the fluid pathway. The negative-pressure applied to the inlet chamber facilitates the use of either negative or positive-pressure based fluid-filtration approaches. Use of the invention improves the functionality and scope of applications that can be performed with enclosed filtration apparatuses.
Abstract translation: 提供了一种方法和装置，用于收集可过滤材料，以通过向过滤装置的入口室施加负压而对过滤装置进行测定，该过滤装置独立于施加到其流体路径的负压或正压。 施加到入口室的负压用于主动地吸入流体并促进经由流体通路流入入口室。 施加到入口室的负压有利于使用负压或基于正压的流体过滤方法。 本发明的使用改进了可以用封闭的过滤装置执行的应用的功能和范围。

Abstract: A dewatering unit in the form of a railcar having bogies thereon to move the unit on rail tracks. The dewatering unit has first and second ends, first and second sides, and a bottom that bound and define an interior chamber. A conveyor is provided in the interior chamber and screens are located in the bottom and first and second sides. A grizzly is located below an opening in the unit's top and above the conveyor. Stabilizing assemblies are deployed to contact the ground and lift some weight off of the bogies prior to loading. A solid material/liquid mixture is dropped through the opening and onto the grizzly which partially fractures the solid material. Further fracturing is undertaken by conveyor drag bars and crushers located adjacent the conveyor. Liquid drains from the unit through the screens. The dewatered solid material is lifted out of the unit by the conveyor.

Abstract: The invention provides a vacuum dehydrating system for gypsum slurry, comprising a vacuum dehydrating apparatus, a first water supply apparatus for supplying filter cake washing water to the vacuum dehydrating apparatus, and a water heating apparatus for heating the filter cake washing water. The invention also provides a vacuum dehydrating method, comprising the following steps: 1) heating the filter cake washing water by the water heating apparatus; 2) supplying the heated filter cake washing water to a vacuum dehydrating apparatus during dehydrating the gypsum slurry by the vacuum dehydrating apparatus. In the invention, the filter cake washing water is heated. Due to the higher temperature of filter cake washing water, the dehydration rate of gypsum slurry is improved so that water content of gypsum filter cake after dehydration is decreased.

Abstract: A method and an apparatus for removing filterable particles from water are disclosed. One or more filter bags made from a filter material suitable for filtering off the particles to be separated are disposed in a body of water with the bottom of the bag situated below the water surface and its opening situated above the surface. The water flows through the wall of the filter bag to the surrounding body of water, while the particles remain within the bag. After a certain amount of particles has been collected in the filter bag, backwashing is carried out and the particles removed and conducted to a place remote from the body of water. The method and apparatus are particularly suitable for restoration of lakes, rivers, water courses and similar water bodies.
