  • Patent number: 7955503
    Abstract: A pure water producing apparatus prevents fluctuations in the amount of produced pure water without requiring a heat exchanger. Raw water is filtered with an activated carbon filtration device, sent through a water supply pump to the reverse osmosis device, and demineralized. Demineralized water output from the reverse osmosis device contacts a water quality sensor including a water temperature sensor, is sent to an electrodeionization device, and subjected to electrodeionization. Water subjected to electrodeionization contacts a water quality sensor having a water temperature sensor, and is taken out as treated water. A sensing signal output from the water temperature sensor is input to a pump control circuit to control an amount of the water supplied from the pump so that an amount of water passing through the reverse osmosis device is maintained constant.

    Abstract: A drain system and method for draining a first liquid, including a collection vessel having a first chamber arranged to receive the first liquid, a second chamber, and higher and lower valves positioned between the first and second chambers. When the valves are open, liquids can pass between the chambers.

A first outlet to the second chamber allows liquids to flow from the second chamber. In a first mode, the first inlet supplies a second liquid at a pressure higher than that of the first liquid in the first chamber such that the valves are closed. In a second mode, the first inlet stops supplying the second liquid such that the pressure in the second chamber reduces relative to the first chamber allowing the valves open.

  • Patent number: 7918994
    Abstract: A system for removing contaminant from sulfur to a level that allows re-processed sulfur to reenter a supply chain. The system melts contaminated sulfur, filters the molten sulfur, and then dispenses the less contaminated sulfur after filtering it. More specifically, solid contaminated sulfur enters a settling tank, while heated molten sulfur circulates through the system and the settling tank. The circulation of the molten sulfur assists in the melting process of the solid sulfur, allowing the solid sulfur to melt efficiently. In preferred embodiments of the system, the system uses steam jacked sulfur lines and steam tracing to maintain temperatures for melting the solid sulfur and maintaining the molten state of the sulfur circulating through the system. Furthermore, the system comprises a programmable logic controller, which controls motors, pumps, valves, and environment monitoring instruments.

    Abstract: A water treatment system including a reverse osmosis module and a control valve controlling communication between a water source and the module. A feedwater biased storage tank stores permeate and its pressurization by feedwater is controlled by a feedwater control valve. Flow of signal pressure to a signal pressure chamber of the feedwater control valve is restricted to reduce the rate at which a fluid generated force is applied. A check valve in parallel with the restriction allows relatively unrestricted flow out of the signal chamber when signal pressure is terminated. A tank pressurization control valve controls the operation of the feedwater control valve and controls the pressurization of a feedwater biasing chamber in the storage tank. Per-meate is stored in an accumulator for flushing the reverse osmosis module when the storage tank reaches a predetermined limit.

  • Patent number: 7857976
    Abstract: A multipurpose hemofiltration system and method are disclosed for the removal of fluid and/or soluble waste from the blood of a patient. The system continuously monitors the flow rates of drained fluid, blood, and infusate. When necessary, the pumping rates of the infusate, drained fluid and blood are adjusted to remove a preselected amount of fluid from the blood in a preselected time period. A supervisory controller can monitor patient parameters, such as heart rate and blood pressure, and adjust the pumping rates accordingly. The supervisory controller uses fuzzy logic to make expert decisions, based upon a set of supervisory rules, to control each pumping rate to achieve a desired flow rate and to respond to fault conditions. An adaptive controller corrects temporal variations in the flow rate based upon an adaptive law and a control law.

  • Publication number: 20100030124
    Abstract: A patient wearable, continuously operating extracorporeal pump apparatus which accesses the patient's arterial venous pressure differential by applying external pressure to a subcutaneous graft that has been cannualized to modulate blood flow through an extracorporeal circuit and to drive the pump for delivering a medicament, such as an anticoagulant, to the site of an intravenous cannula to prevent clogging thereof and also to move a dialysate through a circuit, including a dialyzer and a dialysate rejuvenating cartridge, whereby kidney failure can be treated without recourse to prior art hemodialysis machines found in most treatment facilities. With slight modification, the present invention can be used to remove excess fluids from CHF patients, to remove toxins from the blood in those suffering from liver failure and to facilitate administration of insulin to diabetics and/or glucose to those having hypoglycemia.

  • Publication number: 20090255874
    Abstract: Systems and methods for versatile water purification are provided. A system according to the invention may include a first delivery pump. The first delivery pump may maintain a flow of water into a multi media filter. The multi media filter preferably filters the pumped water. The filtered water may then be pumped by a reverse osmosis pump through a plurality of reverse osmosis columns to produce an osmosis water having less particulate matter than the filtered water. The osmosis water may then be passed to a buffer tank. A second delivery pump for pumping water from the buffer tank may also be used. An ozone system for injecting ozone into water pumped by the second delivery pump may be also implemented. A first output path from the ozone system may pass the ozonated water from the ozone system to the buffer tank via a first valve. A second output path from the ozone system may also be implemented.

  • Patent number: 7578942
    Abstract: In wastewater treatment equipment, a surfactant is added to a micronanobubble reaction vessel 3 by using a surfactant pump 8 and a surfactant tank 9 which constitute a surfactant adding section. Thereby, a micronanobubble generator 4 stably and efficiently produces micronanobubbles in the treatment water as raw water containing the surfactant in the micronanobubble reaction vessel 3. Thus, the micronanobubbles make it possible to efficiently pretreat the wastewater introduced into the micronanobubble reaction vessel. Consequently, it becomes possible not only to enhance efficiency of wastewater treatment but also to reduce a treatment load on wastewater treatment equipment 14 in a step subsequent to the pretreatment. Thereby, scale of the wastewater treatment equipment 14 is reduced.
