| 20100193416 | Non-biological removal and recovery of nutrients from waste - An integrated process that includes liquid-solids separation and filtration system that treats swine or dairy feeding operations residual waste (manure flushwaters) for recovery of solid and dissolved nutrients for reuse and recycling of water from these wastes for a variety of uses. The system includes a coarse liquid/solids system to remove coarse material and multi stage, multimedia filter system that includes a set of modules. Each module includes screen assemblies and filter media sandwiched between the screen assemblies. A plurality of control assemblies is associated with each of the modules. The control assemblies include at least one external valve and are in fluid communication with a corresponding module to control flow through the corresponding module. The control assemblies selectively control fluid in each of the modules between at least one of: a forward flow through the screen assemblies to treat an influent flow, a bypass flow to bypass at least one of the modules, and a reverse flow provided through at least one of the modules. | 08-05-2010 |
| 20100243544 | SEWAGE TREATMENT APPARATUS AND SEWAGE REUSE SYSTEM - The present patent aims to control a water storing quantity of reuse water which is stored by a sewage treatment apparatus of a satellite treatment plant. The sewage treatment apparatus of the present invention comprises: a membrane separation active-sludge treating section which performs a biological treatment on a part of sewage, which is introduced by a water introducing section while flowing through a sewer trunk line, to generate first treated sewage; a membrane highly treating section which performs a membrane high treatment on said first treated sewage to generate second treated sewage; a membrane treating tank which stores said first treated sewage; a membrane highly treating tank which stores said second treated sewage; water level sensors which respectively measure water level of said membrane treating tank and said membrane highly treating tank; and a power-control section which controls water introducing quantity of said water introducing section on the basis of the water level data measured by said water level sensors. | 09-30-2010 |
| 20110220561 | SEAWATER DESALINATION SYSTEM - According to one embodiment, a seawater desalination system includes a membrane filtering pump, a first to third flowmeter, a filtering membrane, a high-pressure pump, a pressure gauge, a reverse osmosis membrane, a discharge valve and a control module. The membrane filtering pump outputs seawater according to a first control signal. The first flowmeter measures flow rate Q | 09-15-2011 |
| 20120080364 | WATER PROVISIONING SYSTEM FOR KITCHEN - The water provisioning system mainly contains a selection switch, a water volume switch, a human-machine interface (HMI), a RO waste water recycling device, an electromagnetic valve, a RO water purification device, an antichlor device, a aeration pipe assembly, a first ozone module, and a second ozone module. The selection switch selects a type of water to use. The RO water purification device filters water from a low-temperature water source, stores purified water in a storage barrel, and provides high-quality drinking water. The 70% water from the RO water purification process that fails the drinking water standard is recycled through the RO waste water recycling device. The low-temperature water source is connected to a antichlor device and the water is therefore dechlorinated. The first and second ozone modules are used to produce ozonated water and to release ozone through the aeration pipe assembly into the kitchen cabinet for deodorization and sterilization. | 04-05-2012 |
| 20140021112 | Systems and Methods for Treating Grey Water On-Board Passenger Transport Vehicles - Embodiments of the present invention provide a system to direct water flow through a lavatory and to cleanse grey water through a series of treatment steps. The water may then be re-directed to the faucet for re-use in hand washing or other potable water use or to the toilet for flush water. The treatment steps are altered, depending upon the ultimate use of the water, as flush water need not be treated to the same level as potable water. The system may also function via a cascade of logic commands given by a series of electronic controllers, valves, and sensors which are fine-tuned to supply enough water to each component of the system. | 01-23-2014 |
