Abstract: The invention in one form is directed to an airlift pump that is optimized to transfer large volumes of water using very low pumping head. Specifically, the airlift pump is comprised of a pump inlet and outlet which are both located below pond's surface. The pumping force driving the water flow is supplied by the weight of the volume of water displaced by pressurized air into a vertical pipe, and this energy is dissipated by the friction of the rising bubbles pipe entrance head, plus the frictional effects of the inner pipe wall and the energy contained in the water's exit velocity.
Abstract: A filter device, in particular for lubricating oil filtration, includes at least two filter inserts (27), in each of which a filter material (43) is accommodated. The filter inserts are provided with fluid passage points (37, 39) and can be stacked on top of one another with the formation of a stack. A back-flushing device (55,57) is movably arranged along the inner side of the filter inserts (27). The individual filter inserts (27) are designed as identical parts at least with respect to their housings.

Abstract: The present invention relates to a method and a device for controlling pollutants in basin water resources cycling utilization in agricultural activity areas. The method includes: providing an acidification tank, an aeration tank and a multi-media constructed wetland connected in sequence, which are 4˜10 m far from basin revetment, feeding basin water into the constructed wetland, adsorbing or degrading heavy metals and organic pollutants by the constructed wetland, and then transporting the treated basin water to the agricultural activity areas. The present invention effectively controls the content of heavy metals that will enter the agricultural activity areas, fundamentally reduces the content of heavy metals in the crops, promotes the growth of the crops, maintains sustainable and healthy development of agriculture, and therefore guarantees human health and safety.

Abstract: Provided is an apparatus and method for interacting with objects of interest. A filtering apparatus can comprise a channel system, through which objects of interest are able to diffuse. The channel system can comprise a channel of suitably configured non-uniform cross-sectional area along the length of the channel. In some embodiments, the channel system can be provided by a suitably configured porous bulk material. In some embodiments, channel system can comprise an interior chamber comprising filtered objects, where the filtered objects are contained on a first side by a first filtering surface, such as a semi-permeable membrane, and on a second side by second filtering surface, where the cross-sectional areas of a representative channel of the first and second filtering surfaces are not identical. The filtered objects can also be configured to interact with an externally applied body force, such as an electric field acting on charged filtered objects.
Abstract: Some embodiments of the invention provide a reverse osmosis water filtration system including a housing, a pre-filter cartridge, a reverse osmosis cartridge, and a post treatment cartridge. A medial water line transports a first portion of pretreated water from the pre-filter cartridge to the reverse osmosis cartridge. An unfiltered water line includes a flow restrictor and blend valve. The unfiltered water line is fluidly coupled between the medial water line and a blend water line. The blend water line receives filtered water at a first flowrate from the reverse osmosis cartridge and unfiltered water at a second flowrate from the blend valve. The first flowrate and the second flowrate are substantially equal to produce a consistent total dissolved solids value.
Abstract: In view of the current pollution to sewage by nitrate nitrogen, the present invention discloses a method for promoting denitrification to remove nitrate nitrogen in water by magnetic resins. In the method disclosed by the present invention, magnetic anion exchange resins are in contact with and mixed with sewage, and nitrate nitrogen in the sewage is removed quickly and efficiently by both the ion exchange between the magnetic anion exchange resins and the nitrate nitrogen in the sewage and the denitrification enhanced by the magnetic material. Meanwhile, the regeneration and recycle of the magnetic anion exchange resins are realized by the denitrification of microorganisms.
