Abstract: A water treatment system provides treated or softened water to a point of use by removing a portion of any hardness-causing species contained in water from a point of entry coming from a water source, such as municipal water, well water, brackish water and water containing foulants. The water treatment system typically treats the water containing at least some undesirable species before delivering the treated water to a point of use. The water treatment system has a reservoir system in line with an electrochemical device such as an electrodeionization device. The water treatment system has a sensor or a set of sensors for measuring at least one property of the water or an operating condition of the treatment system. The water treatment system also has a controller for adjusting or regulating at least one operating parameter of the treatment system or a component of the water treatment system to optimize the operation and performance of the system or components of the system to supply water tailored to quality requirements.

Abstract: Silica and boron are particularly removed at high rate in processing by the electrodeionization apparatus. An electrodeionization apparatus has an anolyte compartment 17 having an anode 11, a catholyte compartment 18 having a cathode 12, concentrating compartments 15, and desalting compartments 16. The concentrating compartments 15 and the desalting compartments 16 are alternately formed between the anolyte compartment 17 and the catholyte compartment 18 by alternately arranging a plurality of anion-exchange membranes 13 and a plurality of cation-exchange membranes 14. The desalting compartments 16 and the concentrating compartments 15 are filled with ion-exchanger. The anion exchanger/cation exchanger volume ratio is 8/2 to 5/5. Electrode water flows into the anolyte compartment 17 and the catholyte compartment 18. Concentrated water is introduced into the concentrating compartments 15. Raw water is fed into the desalting compartment 16 to produce the deionized water from the desalting compartment 16. Water containing silica or boron at a lower concentration than the raw water is introduced into the concentrating compartments 15 as the concentrated water in a direction from a side near an outlet for the deionized water toward a side near an inlet for the raw water of the desalting compartments 16. At least a part of concentrated water flowing out of the concentrating compartments 15 is discharged out of a circulatory system.

Abstract: The dilute support frame is made up of interphase longitude and latitude bars that preferably are hollow. The bars can be rectangular, rectangular with a rounded end, half-circular, triangular, polygonal or any combination thereof. The bars are sized to support the ion exchange resin in the dilute channel adjacent the concentrate membrane bag. The support frame also assures fluent water flow in the dilute channel. The support frames are arrayed on the membranes with interphase aisle to save the frame arrays and make water flow fluently. The membrane envelopes in turn with the support frames as both are preferably wound to form the cylinder module, and is covered by one plastic protecting net. This new type of support frame can assure fluent water flow in dilute channels and convenient resin filling.

Abstract: Apparatus and method are disclosed for introducing ion exchange or other particulates into compartments of an already-assembled electrodeionization or comparable stack by modulating a flow of slurry into the compartments with slugs of gas such as air. The air propels liquid through the cells, scavenging ponded liquid so that the particulates (which are retained, e.g., by a strainer or obstruction, in compartment of the apparatus) are deposited as well-packed beds to fill the compartments. Pressurized air filling protocols may deliver discrete slugs of slurry between bursts of air, and the direction of filling may be periodically reversed to diminish particle bed non-homogeneities or settling gradients that arise during transport. The slugs of air may be applied in the direction of slurry flow, in the reverse direction, or both. Different slurries may be transported in a sequence to form layered and packed beds of enhanced utility. An apparatus of the invention has filled compartments of enhanced packing, and is ported or has its passages arranged so that ion exchange material may be filled, or may be replenished by a fluidized flow according to a method of this invention.

Abstract: An electrodeionization (EDI) module is formed an anode spaced apart from a cathode, one or more waste channels formed between the electrodes and a product channel located inward of the waste channel(s). Ion permeable membranes form the boundary between the product channel and the waste channel(s). The product channel and waste channels are filled with a mixture of anionic and cationic ion exchange materials. At least the waste channel(s) and preferably the product channel as well, use either an anion bead having a relatively low affinity for the selected anion specie(s) to be retained (e.g. Type II) or it is a blend with Type I materials. Preferably, the membranes contain an ion exchange material to speed the transfer of ions across them. More preferably, the anionic membrane contains anion materials that have a relatively low affinity for the selected specie or species for retention.
