| 20100012558 | WASTEWATER TREATMENT SYSTEMS AND METHODS - Systems and methods for wastewater treatment. A nitrate source may be dosed to a collection tank, such as a wet well, for downstream control of hydrogen sulfide levels in the wastewater. A source of a strong oxidizer may also be dosed to the wet well. The oxidizer, such as chlorite, may temporarily interrupt denitrification processes in the wet well to prevent floatation of undesirable constituents therein. The oxidizer dosage may be generally consistent with the nitrate dosage. An ORP sensor may facilitate regulation of dosing. The nitrate and the oxidizer may be present in a single mixture to be dosed to the wet well. | 01-21-2010 |
| 20100018912 | Water filter device having encoding structure - The present invention relates to a water filter device comprising a filter head with filter head components, a replaceable filter candle with filter candle components, and an encoding structure which is formed between a filter head component and a filter candle component. Said water filter device is distinguished, in a first embodiment, in that an encoding structure is formed with axial orientation on an end face of the filter candle and/or on an element which is associated with such an end face of the filter candle. In a second embodiment, said water filter device is distinguished in that an encoding structure is formed separately from a fixing structure. | 01-28-2010 |
| 20100038293 | Water treatment apparatus - An apparatus for treating waste water comprises a mixing chamber including mixing members therein for mixing waste water and treatment chemicals therein and a separating chamber at the outlet of the mixing chamber for separating the flocculated contaminants and to provide a supply of clarified water. In a preferred embodiment, the chemicals are injected at sequential locations along an injection tube for sequential mixing of the chemicals with one another in the injection tube prior to the chemicals being injected and mixed into the mixing chamber for mixing with the waste water. | 02-18-2010 |
| 20100059424 | WATER FILTER DEVICE WITH CONTROL UNIT FOR SETTING A CUTTING RATIO - The present invention relates to a water-filter device. This is distinguished by the provision of an adjusting medium ( | 03-11-2010 |
| 20100200477 | APPARATUS FOR TREATING A WASTE STREAM - An integrated unit operations for the treatment of a waste stream, such as spent caustic, is provided in a single vertical vessel having at least three separate zones: a mixing, a settling, and a mass transfer zone. | 08-12-2010 |
| 20110036761 | AUTOMATIC OZONE WATER OUTPUT DEVICE - An automatic ozone water output device includes a faucet unit, at least one water inlet pipe, and an ozone generator. The faucet unit will automatically detect the presence of a user to output water. The water inlet pipe having a Venturi section connects the faucet unit and a water source. An ozone generating device having a pressure-sensitive activator is kept in a concealed space or a sheltered location, such as in the area under a basin or a sink. When water flows through the Venturi pipe, a negative pressure is developed and sensed by the pressure-sensitive activator. In response, the pressure-sensitive activator activates the ozone generator, thereby causing the mixing of ozone with the discharged water. | 02-17-2011 |
| 20120292237 | DIALYSIS MACHINE - A disposable cartridge for use in a hemodialysis machine has a blood flow path for carrying a volume of blood to be treated in a dialyser and a dialysate flow path, isolated from the blood flow path, for delivering a flow of dislysate solution through the dialyser. The cartridge is received in an engine section of the machine. The engine section has first and second platens which close when the cartridge is inserted to retain the cartridge. Actuators and sensors arranged on the second platen control operation of the cartridge. | 11-22-2012 |
| 20130037463 | WASTEWATER TREATMENT SYSTEM - The present invention is a system and method for treating a wastewater stream to produce an effluent having an acceptable level of turbidity. The invention comprises a controller operatively coupled to at least one turbidity meter for monitoring turbidity of the effluent stream. A plurality of chemical treatment additive pumps are provided for providing a plurality of additives to the wastewater stream. Furthermore, a method of sequentially testing the amount of each additive required to produce an effluent stream having an acceptable turbidity is disclosed. | 02-14-2013 |
| 20140319032 | COMPACT WASTEWATER CONCENTRATOR AND CONTAMINANT SCRUBBER - A compact and portable liquid concentrator and contaminant scrubber includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. A reagent may be mixed with the liquid to react with contaminants in the liquid. | 10-30-2014 |
| 20150034537 | Automatic Drinking Water Enhancement Apparatus - This invention is for an automatic drinking water enhancement apparatus consisting of a storage reservoir for water enhancement liquid connected to a positive displacement pump that will pump said water enhancement liquid proportional to the drinking water supply flow rate, and a merging and mixing means to combine the two streams, and an output leading to the dispenser to the user. The positive displacement pump may be powered by the drinking water stream flow and pressure, or by an electric motor with suitable electronic or computerized controls and sensors to drive the motor and infusion pump speed proportional to the filtered water flow rate, or as otherwise controlled. Fixed and variable control of the water enhancement liquid concentration in the output drinking water stream are included. Because it operates automatically, in the simplest embodiment the use requirements for this apparatus are the same as using a filtered water delivery faucet, plus keeping the water enhancement reservoir filled on occasion as necessary. If a user controlled water enhancement concentration approach embodiment is used, the user will have the additional use requirement to adjust the control input device to specify the desired water enhancement liquid concentration. | 02-05-2015 |
| 20160000990 | DIALYSIS MACHINE - A dialysis machine which includes a preparation system comprising a main line for the dialysis liquid, several supply lines for respective concentrates opening at said main line is disclosed. At a point behind each orifice a respective mixing chamber is arranged and after the latter a respective conductivity probe is disposed. Downstream of the last conductivity probe, a shared pump is arranged. The negative pressure in the main line is adjusted via a pressure control valve which is arranged upstream of the first orifice in the main line. Furthermore, a proportional valve or a digital switching valve is disposed for metering the various concentrates in each supply line. The pressure control valve and the proportional valves or switching valves are controlled in electromagnetic fashion by a central electronic control unit. | 01-07-2016 |
