摘要： A biological reactor system treats concentrated contaminated water with a combination of upflow and downflow bioreactors that are downstream from a reverse osmosis or other concentrator. The system may have a fail safe configuration where flush water may be introduced to the reactors in the event of a power failure or when taking the reactors offline. Many reverse osmosis systems introduce antiscalant treatments upstream so that the reverse osmosis filters do not scale. However, such treatments result in superconcentrated conditions of the antiscalants in the contaminated water processed by the bioreactors. A flushing system may deconcentrate the bioreactors to prevent the antiscalants from precipitating and fouling the bioreactors.

摘要： The present invention provides method of removing particles from a feed fluid, the method comprising: passing the fluid through a first filtration medium having a thickness of from 5 to 20 μm, wherein passing the feed fluid through the first filtration medium provides a particle removal probability log10 reduction value (LRV) of greater than or equal to 1 for particles having a diameter of from about 10 to about 40 nm and a particle removal probability log10 reduction value (LRV) of greater than or equal to 3 for particles greater than about 40 nm in diameter; and passing the fluid through a second filtration medium having a thickness of from 20 to 70 μm (e.g. 20 to 45 μm) 20 to 45 pm, wherein passing the feed fluid through the second filtration medium provides a particle removal probability log10 reduction value (LRV) of greater than or equal to 3 for particles having a diameter of from about 10 to about 40 nm and a particle removal probability log10 reduction value (LRV) of greater than or equal to 3 for particles having a diameter of greater than or equal to about 40 nm; so as to retain at least a portion of the particles on each medium to produce a filtrate containing a lower concentration of the particles than the feed fluid.

摘要： Method for treating impurities contained in exhaust gases of ships to reduce sulphur oxide and other emissions. In order for the method to purify wash water exiting from an exhaust gas scrubber sufficiently enough to be directly dischargeable to sea, and in order for a purification unit used to be small enough to be easily placed onboard a ship, exhaust gases are scrubbed in the exhaust gas scrubber and wash water containing impurities and exiting from the scrubber is supplied to the purification unit, circulated in an effluent circuit, and filtered through a semipermeable membrane of a filter to obtain purified effluent and a residue containing impurities, when necessary, the pH value of the purified effluent is adjusted to be at least 6.5, after which it is discharged into the sea or recycled to the scrubber while the residue containing impurities is led back to the effluent circuit.

摘要： A method for treating produced water in a system for treating wastewater is disclosed. The system includes a reverse osmosis unit for removing dissolved solids. The reverse osmosis unit produces a permeate and concentrate. To reduce the fouling potential of the membranes associated with the reverse osmosis unit and/or to increase membrane lifetime and/or to increase system recovery, at least a portion of the concentrate is recycled and mixed with the wastewater stream at a point upstream of the reverse osmosis unit.

摘要： Provided is a method for controlling a pH to a neutral range (pH 6 to 8) by adding an alkali or an acid to decarbonated water, including controlling the amount of the alkali or the acid added using an electrical conductivity meter. The decarbonated water is, for example, water obtained by decarbonating industrial water or groundwater so that the concentration of carbonic acid is 10 ppm or less. The method may further have a step of producing pure water by RO treatment of the decarbonated water with a pH adjusted to 6 to 8 by the pH control.

摘要： A wave-actuated system for desalination of water by reverse osmosis (RO) having a wave energy converter (WEC) subsystem and a RO desalination subsystem is disclosed. The WEC subsystem has a float, a reaction member, and a hydraulic cylinder connected between the float and the reaction member and defining first and second variable volume chambers The RO desalination subsystem has a RO cell containing a RO membrane and a flow smoothing device (FSD). During a first stroke of the WEC subsystem: the float moves in a first direction; and seawater is supplied from the first variable volume chamber to the RO cell and to the FSD. During a second stroke of the WEC subsystem: the float moves in a second direction; seawater is supplied from a seawater intake to the first variable volume chamber; and seawater is supplied from the FSD to the RO cell.
