Abstract: An extracorporeal reservoir device including a housing, a venous inlet sub-assembly, and a venous filter. The venous sub-assembly is mounted to the housing and includes a downtube and a luer port connector body. The connector body extends from the downtube and forms a passageway open to a lumen of the downtube. The connector body is arranged such that fluid flow from the passageway merges with a flow path of fluid along the primary lumen at an angle of less than 90°. Secondary blood flow through the port connector body is less likely to induce turbulent flow into venous blood flow within the downtube, and is thus less likely to break up any bubbles carried by the venous blood. For example, at port flow rates of less than 500 mL/minute, fluid flow from the port connector body does not induce turbulent flow into fluid flowing through the primary lumen.

Therefore, a filter exchange period can be accurately determined by measuring properties of the filter varied during filtering of contaminants, and indiscriminate exchange of the filters can be prevented to reduce maintenance cost.

Abstract: A gray water recycling system which uses a holding tank receiving waste water from a laundry facility. The holding tank has a pump for withdrawing water from said holding tank. A float, within said holding tank, is activated when a water level within said holding tank exceeds a pre-determined level. The pump communicates with a pressure tank. The pump used to fill and pressurize the pressure tank is activated when pressure within said pressure tank falls below a predetermined level and the float within said holding tank indicates that a water level within said holding tank exceeds a pre-determined level.

Abstract: Conditioning processes and equipment for removing hardness from water circulated in a system. A sidestream is routed to a reactor and back. A buffer is added to the circulated water, in some embodiments in a sidestream exiting the reaction chamber, forming soluble metal complexes with metal ions of the type that cause scaling. A conditioner is added to the sidestream water which breaks the soluble metal ion-buffer complexes and precipitates and accumulates the released metal ion as a solid for accumulation and disposal. In some embodiments a polymer is added, a corrosion inhibitor blend is added and/or pre-mixed with the buffer, and a chlorine generator removes sodium chloride from the buffered sidestream, and makes chlorine gas, hydrogen gas, and sodium hydroxide for use in the process or for disposal.

Abstract: Systems, methods, and devices for preparation of water for various uses including blood treatment are described. In embodiments, fluid is passed either by pump or passively by gravity feed, through various filtration elements from a fluid source to a treatment fluid container The latter forms a batch that may be used during treatment. Methods and systems for creating multiple-treatment batches are described. Advantages of creating a multitreatment batch include the fact that the burden of treatment preparation can be reduced and the timing of the preparation of the batch can be independent of the treatment time. As described, there are various trade-offs and concerns with this approach which are addressed by the inventive embodiments.

Abstract: An in-line water monitoring system for the detection of the accidental or intentional introduction of potentially harmful substances. The automated system comprises a water pressure driven concentration unit that filters drinking water through a hollow-fiber filter. Material collected on the filter is backflushed into a collection vessel by passing a sterile solution through the filter in the reverse direction. An electronic signal at the end of the backflush sequence triggers a sensor such as an array biosensor to begin processing and analyzing the sample. The array biosensor houses a slide prepared with antibodies to the test organism. The array biosensor is programmed to automatically run sample and detection reagents over the slide, analyze the resulting pattern for positive and negative data, and report the results.

Abstract: A method of and system for purifying fluid of an internal combustion engine or hydraulic system utilizes an evaporation chamber separate from a filtering chamber. A metering valve may be oriented between the filtering chamber and the evaporation chamber to control the flow of fluid to the evaporation chamber.

Abstract: Methods for recovery of tartrate-containing, insoluble solids from an essentially settled grape-based mixture. More generally, methods for the recovery of insoluble solids, that have a predetermined characteristic from essentially settled mixtures are disclosed. The methods include performing proxy analyses on samples taken from the mixtures in order to determine at what time recovery should begin and end. Performing titration is detailed as a particular proxy analysis.

Abstract: A refrigerant filter, attachable to automotive air-conditioning systems, for removal of debris from air-conditioning refrigerants. The filter media is contained within a two-part hollow body for flow-through filtration of the refrigerants. The first and second parts of the hollow body are sealingly and removably attachable to one another to easily gain access to the filter media, which permits replacement of the filter media without removal of the filter body from the refrigerant line. The apparatus includes a first and second filter media, in which the second filter media prevent transfer of portions of the first filter media into the air-conditioning system.

Abstract: A system for separation of fluids and drill cuttings received from a borehole during an under-balanced drilling procedure. The system is designed to cope with significantly varied pressures and flow rates, particularly in relation to gas content of drill fluids returned to the surface during the drilling process in a production zone, and to provide effective separation and to reduce the detrimental effect due to the presence of the drill cuttings in the returned drill fluids. In the present invention there is utilized a first stage, high pressure vessel in which a major portion of the gases ad drill cuttings are separated, and a second stage, horizontal low pressure vessel, preferably of greater volume than the high pressure vessel, in which further separating is achieved, including the separate removal of the drilling liquid to be returned to the drill tube.

Abstract: An improved oil reclamation device for removing solid contaminates and water or other volatile contaminates from the engine lubricating oils and hydraulic fluids. More particularly, this oil reclamation device relates to a unique combination evaporation chamber and filter housing, and to an improved filter assembly. A first feature of this oil reclamation device is the improved utilization of space through the efficient combining of the filter and evaporation chambers within one compact housing, which utilization brings the benefits of a compact installation with a minimum difficulty of installation. Another benefit of this design is the efficient use of engine oil to heat the evaporation surface evenly and effectively without the need of any additional heat source. This design eliminates cold spots on the evaporation surface and the need for potentially dangerous heating elements. Further, many different types of filter elements and filtration ratings may be used.

Abstract: An apparatus and method for removing free and emulsified water as well as solid contaminants from an oil/water mixture produced in lubricating the bearings of a steam turbine employs a singular, closed housing having a lowermost, filter-free gravity chamber, an uppermost filter element chamber, and a filter-free water collection chamber between the gravity chamber and the filter element chamber. The oil/water mixture introduced into the housing has its free water component removed in the gravity chamber and has its emulsified water and solid contaminant components removed by coalescence in the filter element chamber. Free water, emulsified water and solid contaminants are collected, monitored and selectively drained from the water collection chamber and gravity chamber.

Abstract: This invention relates to filtering or straining of fluids where the suspended solids removed by filtration must eventually be discharged from the filter as a "dry cake" discharge. The apparatus provides for the use of a central flow tube positioned within a filter element which is connected to a filter element drain pipe through a valve, which in case of multiple filter elements within a filtration vessel, controls draining of all elements. To assist in detecting a defective or malfunctioning filter element, a sample conduit with a sample valve is provided independently for each filter element.
