20120181226Medical Fluid Cassettes and Related Systems - The invention relates to an apparatus for the treatment of a medical liquid comprising a liquid treatment machine and a cassette insertable therein substantially made of a rigid base body of the cassette with fitted chambers and passages and a foil covering them.07-19-2012
20080314816Settling and retention basin - A settling and retention basin includes an interior chamber having a peripheral wall preferably provided with two diametrically opposite openings in each of which is received a flow port member having a flow equalization port therein. Depending upon wastewater levels and surges, the flow port members can be removed and replaced by other flow port members of an identical construction, except for different sizes of design flow equalization ports thereof. Therefore, should a wastewater treatment mechanism be installed initially in a wastewater treatment plant with accurately sized flow equalization ports to achieve desired flow characteristics and efficiency, should such flow characteristics change over time because of inefficient flow-through of wastewater, the originally installed flow port members can be readily removed and replaced with identical flow port members except for larger flow equalization ports thereof thereby returning the overall wastewater treatment mechanism to acceptable design flow equalization and efficiency.12-25-2008

The thinned edges of the feed spacer material are located in the element between glue lines applied to the permeate spacers of the element. The thin edges allow a greater membrane surface area to be provided in a given element diameter. A feed channel spacer may also have an area with obstructions to create micro-mixing effects. These obstructions may be provided on a feed spacer sheet of constant thickness, or one with thin edges.06-13-2013

20080203006Self-standing weighted diffuser assembly - An apparatus designed to convert the dynamic of residential wastewater treatment processing bacteria from anaerobic to aerobic bacteria in existing single or multiple compartment septic tanks. The apparatus consists of a small self-standing weighted diffuser assembly designed with a center tube having a specific series of vertically lined orifices and a deflector plate that can be lowered through an 8-inch diameter opening by means of the attached flexible airline into an existing septic tank and sit directly on the bottom of the septic tank. A flexible airline attaches the diffuser assembly to a small air pump located outside of the septic tank. When the air pump is activated, air will enter the diffuser assembly and discharge through the orifices a combination of fine and coarse air bubbles. This action causes the wastewater to be forced against the deflector plate and creates a rolling action starting at the bottom of the septic tank and rolling upwards toward the outside of the tank. This rolling wastewater is forced to the top of the liquid level in the septic tank and then is pulled back down to the bottom and back toward the diffuser where the cycle begins again. This unique action takes place on all sides of the diffuser assembly very quickly breaking solids down into small particles. Additional benefits include the production of sufficient oxygen in the wastewater to proliferate the growth of aerobic bacteria. With the constant rolling action of sewage and particles, it is necessary especially in a single compartment septic tank to eliminate those particles from exiting the tank and entering into the secondary treatment system. The apparatus is designed to draw those small waste particles down and away from the septic tank discharge point, and back toward the diffuser assembly ensuring those particles do not exit the septic tank.08-28-2008

In another implementation, various hydrophilic and/or hydrophobic surfaces are disposed in multiple differential extractors and some effluents may be recycled to perform complex assaying and separation. In a further implementation, an apparatus can draw off purified water just beneath the air-water interface.05-28-2009
20120125836SEPARATION APPARATUS AND PROCESSES - An apparatus may include a separator and/or a discharger.

A discharger may be disposed below a fluid-lift portion and/or may include a portion external to a separator channel, which may include a downward angle relative to an effluent portion and/or may be configured to minimize the passage of a second fluid into a discharger as the second fluid buoyantly travels in a separator channel from an influent portion to an effluent portion. A second fluid may have a density that is less than the density of a first and/or may be configured to lift a first fluid to a fluid-lift portion.05-24-2012
