20120074074 | SELF-CLEANING SCREEN SYSTEM AND METHOD - A self-cleaning screen system and method removes contaminants from a fluid passed through a screen of the self-cleaning screen system. The self-cleaning screen system includes a cleaning mechanism used to remove contaminants which may have adhered to the screen. The self-cleaning screen system is self-powered by extracting energy from the fluid flow to cause rotation or other movement of either the screen and/or the cleaning mechanism. | 03-29-2012 |
20120145546 | ALL-ELECTRIC COAGULANT GENERATION SYSTEM - A coagulation generating system that combines the advantages of conventional and electrocoagulation. In the coagulation generating system electro-coagulation is performed on an input (e.g., salt/brine) solution to generate a concentrated coagulant solution, which is then added to the source water in the same way as a standard stored chemical coagulant. | 06-14-2012 |
20120145647 | ELECTROCOAGULATION SYSTEM - An electrocoagulation system including a dosing unit, a mixing unit and a buffer tank is provided. The dosing unit receives a fluid from an external source and injects an electrochemically generated coagulant into the fluid using one or more pairs of electrodes. The mixing unit mixes the coagulant with the fluid and is separate from the dosing unit. The buffer tank holds the fluid until particles contained in the fluid grow to a predetermined size. | 06-14-2012 |
20120152814 | MEMBRANE BIOREACTOR (MBR) AND MOVING BED BIOREACTOR (MBBR) CONFIGURATIONS FOR WASTEWATER TREATMENT - The water treatment system and method incorporating the use of a hydrodynamic separator to remove most of the total suspended solids (TSS) in source water being treated to thereby lighten the load on membrane filtration in the water treatment system and lower energy costs. | 06-21-2012 |
20120152855 | SYSTEMS AND APPARATUS FOR SEAWATER ORGANICS REMOVAL - A non-filtration pre-separation device and method for the removal of algae using the same, comprising a system having a hydrodynamic separator including at least one curved structure for the removal of bio-organisms from seawater, such structure having an inlet in operative connection with a source of raw seawater and a bifurcated outlet operative for passing pre-treated effluent fluid to a downstream filtration system and the removal of waste fluid. Various fluidic structures, implementations and selected fabrication techniques to realize such a device, whether singular or in stacked and/or packed parallel configuration are also provided. | 06-21-2012 |
20140146110 | BYPASS FLOW PATH FOR INK JET BUBBLES - An apparatus includes a bypass flow path between an ink supply port and a vent port and a primary flow path between the ink supply port and an ink delivery port. A first flow velocity of the bypass flow path is higher than a second flow velocity of the primary flow path. The first flow velocity induces bubbles to travel via the bypass flow path instead of the primary flow path. | 05-29-2014 |
20140168315 | TRAP CONFIGURED TO COLLECT INK PARTICLE CONTAMINANTS IN RESPONSE TO A CLEANING FLOW - An apparatus includes an inkjet manifold with at least one ink supply port coupled to an ink supply and at least one ink delivery port. A flow path is between the ink supply and ink delivery ports, and the flow path includes a trap configured to collect particle contaminants in response to a pulsed cleaning flow and hold the particle contaminants during an operational flow. | 06-19-2014 |
20140262973 | METHOD AND SYSTEM FOR STACKING AND SEALING HYDRODYNAMIC SEPARATION LAYERS - An assembly for a high output hydrodynamic separation unit includes, in one form, several components or parts. Top and bottom plates serve as caps for and distribute force through layers of separation channels. The compressive forces seal the channels and prevent leakage from the channels. An optional middle plate may also be provided to create smaller subsets of the layers of separation channels. At least one connector is provided to the combination of components to compress the layers of separation channels. In a variation, an optional outer shell may encase the unit to provide support and compress the stack with a unique threaded configuration. | 09-18-2014 |
20140264080 | PHASE-CHANGE ENABLED FLOW FIELD VISUALIZATION - A system and method for visualization of fluid flow, includes a light emitting arrangement configured to emit a focused light, a fluid channel configured to hold a fluid including a carrier liquid and a stimuli responsive polymer, wherein the fluid flows though the fluid channel, and an image recording arrangement. The light emitting arrangement is positioned to emit the focused light into a selected area of the fluid channel to interact with the flowing stimuli responsive polymer within the selected area. This results in a phase change to a portion of the stimuli responsive polymer. The image recording arrangement is positioned to record an image the portion of the phase changed stimuli responsive polymer made visible by the phase change. | 09-18-2014 |
20140268077 | A FLOW LITHOGRAPHY TECHNIQUE TO FORM MICROSTRUCTURES USING OPTICAL ARRAYS - A continuous flow projection lithography system to form microstructures using an optical array incorporated in a continuous coating process is provided. A mask is placed at a distance from the array. Each element of the array projects one image of the mask onto a substrate, effectively forming an array thereon. A coating process allows flows that can be used to define functional regions of particles or supporting layers that prevent adhesion of crosslinked polymers to surfaces. | 09-18-2014 |
