Abstract:
A portable water conditioning system is provided that includes an incoming water inlet; a reverse osmosis stage in fluid communication with the incoming water inlet, the reverse osmosis stage having a permeate outlet and a concentrate outlet; a diversion device having a diversion valve, the diversion valve placing the concentrate outlet in fluid communication with a waste water outlet; a deionizing stage in fluid communication with a pure water outlet; a bypass valve configured to selectively place the permeate outlet in fluid communication with one or more of the waste water outlet, the deionizing stage, and the pure water outlet; and a controller configured to control the diversion device and the bypass valve to provide water at the pure water outlet of a desired condition.
Abstract:
The invention relates to a filtration system (10) for liquid, particularly raw water, comprising at least one filtration module (20) for filtering the liquid, a first inlet pipe (21) for feeding liquid to the filtration module (20), a second inlet pipe (22) for feeding liquid to the filtration module (20) and at least one outlet pipe (26) for discharging filtrate from the filtration module (20). A cleaning branch (80) is arranged between the first inlet pipe (21) and the second inlet pipe (22), and at least one dosing feeder (81, 82, 83) for adding a cleaning chemical is connected to the cleaning branch (80). The invention also relates to a method for chemical rinsing a filtration system (10) for liquid, particularly raw water, comprising at least one filtration module (20) for filtering the liquid, a first inlet pipe (21) for feeding liquid to the filtration module (20), a second inlet pipe (22) for feeding liquid to the filtration module (20) and at least one outlet pipe (26) for discharging filtrate from the filtration module (20). In chemically rinsing operation, a cleaning chemical is added via a dosing feeder (81, 82, 83) connected to a cleaning branch (80) which is arranged between the first inlet pipe (21) and the second inlet pipe (22).
Abstract:
A fluid treatment system comprises an inlet to receive fluid (1) from a fluid feed source, a feed fluid treatment unit (2) and one or more downstream treatment units (6). The system further comprises a treated fluid recirculation loop (12a, 12b) from an outlet of at least one of the feed fluid treatment unit (2), or the downstream treatment units (6); and a controller (13).
Abstract:
The invention concerns a water treatment system (1) and a method for treating water (2) located in a water reservoir (3). The water treatment system (1) comprises a recirculation means (4) disposed within which there is a membrane filtration means (9) with a plurality of filter modules (10). The water treatment system (1) particularly comprises a gas supply means (24) by which gas can be introduced into the filter modules (10) of the membrane filtration means (9) to clean their membranes, or into the water reservoir (3) at one or more locations, periodically or when required, to circulate or mix up the water (2) therein.
Abstract:
An object of the present invention is to provide a reverse osmosis membrane filtering device capable of reducing variation in the amount of permeate water in the axial direction of water collecting pipes regardless of the number or length of the water collecting pipes. The reverse osmosis membrane filtering device includes: a water-collecting member including at least one water collecting pipe, and having a plurality of sections each of which has a plurality of water collecting apertures; at least one filter assembly disposed around the plurality of sections, the at least one filter assembly including a filter member including a reverse osmosis membrane; at least one insertion tube disposed inside the water-collecting member and defining a plurality of permeate-water channels corresponding to the plurality of sections inside the water-collecting member in cooperation with at least one seal member; and a pressure adjusting device configured to increase a pressure of at least one of the plurality of permeate-water channels to a pressure higher than that of another one of the plurality of permeate-water channels.
Abstract:
Disclosed herein are apparatus and methods for filtering a fluid including a filter module assembly coupled to a manifold. The manifold may include a manifold inlet in fluid communication with a source of feed liquid, an outlet in fluid communication with header of the filter module assembly, a fluid passageway in fluid communication with the manifold inlet, a source of gas, and the outlet, a second fluid passageway in fluid communication with the header and the first fluid passageway and a second manifold outlet vertically displaced from the first manifold outlet and in fluid communication between the first fluid passageway and the second fluid passageway.
Abstract:
A method for treating water including intaking a first amount of water into a plurality of treatment blocks, treating the first amount of water, outputting aqueous treated water streams from each of the plurality of treatment blocks, separating the aqueous treated water streams from each of the plurality of treatment blocks into aqueous permeate streams and concentrate reject streams, monitoring each of the aqueous permeate streams, controlling the operation of at least one of the plurality of treatment blocks based on predefined water-characteristic tolerances that fall within a predetermined concentration range based on the different qualities of the aqueous permeate streams, combining the aqueous permeate streams of at least two of the plurality of treatment blocks based on the identified characteristics and the predefined water-characteristic tolerances, and outputting the product water stream and the at least one concentrate reject stream.
