Submerged gas diffuser assemblies configured to aerate liquid suspensions in reservoirs or deep shafts with enhanced aeration contact patterns and adjustable aeration rates. Aeration contact patterns and rates are varied by the adjusting the spatial configuration of gas permeable membranes, altering the fluid flow patterns around the membranes, manipulating trans-membrane pressures across membranes, varying the sequence of aeration of liquid within the fluid flow patterns, expanding the membrane surface area, and/or by selectively occluding certain portions of membrane surface area of the membrane assemblies. The membrane assemblies are designed to prevent, control, or mitigate membrane fouling and hydro lockup.

Filtration systems (40) utilize a pre-treatment method to cause scale formation to occur on particles (94) in the fluid stream (96) rather than on the filter surface and may also destroy microorganisms in the fluid stream. More specifically, but not limited to, a filtration device can be a filtration membrane, such as spiral wound filtration membrane (60), that utilizes an open feed spacer (80), such for example an embossed or printed pattern on the membrane, to create a thin feed spacer channel which replaces a conventional feed spacer mesh material. System (40) further utilizes a treatment device (54) to enable a pulsed power, magnetic, electro-magnetic, electro-static, or hydrodynamic fluid treatment scheme to condition particles in the fluid stream (96) such that scale forming elements precipitate (94) on to the particles in the fluid stream rather than on the filtration surfaces.

The invention relates to a method for preparing graphene, characterized by carrying out explosion treatment for one or more times on carbonaceous materials by using fluids under supercritical state. By using the fluids under supercritical state to penetrate and dissolve the carbonaceous materials and having the aid of sudden release of high pressure hot steam, the shearing and peeling between layers of the carbonaceous materials are promoted to realize the preparation of graphene. Compared with using ball milling, mechanical peeling, high temperature and high pressure to prepare graphene in the prior art, the invention has the advantages of mild process conditions (low pressure), short process time, large area of prepared graphene, and complete preserved crystal structure. According to the invention, the content of graphene which comprises less than 5 layers is higher than 90 %, and the batch production of graphene powder products can be really realized.

The stimulated rock volume (SRV) of a subterranean formation may be increased by pumping viscous fracturing fluid into the formation in a first stage to create or enlarge a primary fracture, decreasing the pumping in order for the fluid to increase in viscosity within the primary fracture, and then continuing to pump viscous fluid into the formation in a second stage. The fluid pumped into the second stage is diverted away from the primary fracture and a secondary fracture is created. The directional orientation of the secondary fracture is distinct from the directional orientation of the primary fracture. The fluid of the first stage may contain a viscosifying polymer or viscoelastic surfactant or may be slickwater.

The present invention is a method for refining native biomass to extremely fine and highly disrupted particles using high shear and/or cavitation in combination with high temperature and high or low pH conditions which dissolve biomass to a high percentage. The method of the present invention results in a high percentage of hydrolysis, in many cases near theoretical levels, in short residence times while minimizing inputs over other methods, using low chemical inputs, and optionally with no chemical inputs in certain stages compared to existing processes. The method of the present invention also uses minimal electrical energy inputs and conserves heat energy within the process and reduces equipment requirements while producing concentrated products.

The invention relates to the field of assembly concrete buildings, in particular to an assembly concrete new type pillar and beam structure and an assembly connecting method. Assembly concrete new type pillars and an assembly concrete new type beam can serve as pillars and a beam applied to the assembly concrete buildings. The assembly concrete new type pillar and beam structure comprises a prefabricated pillar and prefabricated beam structure, and each prefabricated pillar comprises a prefabricated side pillar and a prefabricated center pillar. Grouting grooves are formed in the top and the bottom of each prefabricated pillar, and the connected grouting grooves are grouted with a grouting material to achieve equal-shearing-strength connection between the prefabricated pillars; as beam steel bar penetrating holes are reserved in the prefabricated pillars, prefabricated beam steel bars can directly penetrate through the prefabricated pillars to be connected with the prefabricated pillars; as steel poles provided with threads at the ends are pre-buried in the prefabricated beam to transmit shearing force and pull force between the prefabricated beam and post-poured concrete, and the steel poles with the threads at the ends can serve as connecting pieces for fixing a prefabricated slab to the prefabricated beam. By the adoption of the method, connection between precast concrete members is more reliable and economical.

Hydrogenated vegetable oil exhibiting superior thermal stability and containing reduced levels of saturates and trans fatty acids are produced using an activated hydrogenation catalyst and/or an improved hydrogenation process incorporating high shear. The use of a high shear mechanical device incorporated into the hydrogenation process as a reactor device is shown to be capable of enabling reactions that would normally not be feasible under a given set of reaction pressure and temperature conditions. For example, the hydrogenation process described herein enables a reduction of hydrogenation time, and operation at lower temperatures than current processes. The resulting hydrogenated vegetable oil is particularly useful in frying, confectionery baking, and other applications where a product with a low trans fat content or higher thermal stability is desirable. The hydrogenated oil produced may comprise less than 10 weight % of trans fatty acids with less than 5 weight % of linolenic acid (C_18:3).
