example 2

[0098] An example of a transformer design of the present invention is described in Example 2 which facilitates the optimization of practical, useful flux leakage bridges in high voltage low frequency transformers.

[0099] Large ERIX tank

[0100] The previously described ERIX tank designs (eg, point-of-use (POU) potable water systems in residential applications) are effective for small systems that have been commercialized. as above and as Figure 1A , 1B and 2, these cells contain: a housing with an integral electrode; a separate capsule containing a bipolar membrane wrapped around a detachable and replaceable core mesh tube; and a housing cover . In one embodiment, the cover is integral with the bellows. In another embodiment, the cover is separate from the bellows. The electrodes are integral to the housing, and since they are relatively expensive, designed for the lifetime of the system (e.g., 10 years), for safety and certification purposes, the electrical connecti...

example 1

[0122] An incoming solution with a conductivity of 950 S / cm was prepared from calcium chloride, sodium bicarbonate and magnesium sulfate. In four experiments, using the produced by the company The 140 potable water system was deionized with increased service volume consisting of two small LINX 100 TDS capsules fabricated with textured bipolar membranes (LINX and Pionetics are trademarks of Pionetics Corporation). Continuous deionization of service volumes of 6 L, 12 L, 18 L and 24 L at 1.9 L / min with deionization flow and power off for 3 minutes until programmed to end (and regeneration begins) at the deionization step Before reaching 2.0 liters. A volume of 2.0 liters was collected and its conductivity recorded. After a 3 minute interruption, deionization flow and power were restored while four 0.5 liter volumes of produced water were collected, the conductivity of which was also measured. The results are plotted on Figure 7 middle. The conductivity spikes observed a...

Abstract

A fluid treatment apparatus is constructed from at least one electrochemical cell including a bipolar ion exchange membrane and having a single output orifice to deliver treated fluid. The apparatus may employ a power supply transformer featuring a magnetic dispersion bridge to regulate the magnetic flux to secondary coils, thereby limiting the current delivered to the load and protecting the apparatus from over-current damage. The cell includes a membrane assembly which incorporates both the inner and outer electrodes to provide repeatable assembly and service, as well as reliable performance. The apparatus will provide continuous fluid treatment when designed with at least two stages, each stage including at least one cell, in which one stage is treating influent solution and another stage is regenerating. A method to operate these apparatus includes the steps of deionizing influent solution without interruption, halting deionization water flow and removing power from the deionization cells, flushing the liquid between membrane layers to the drain outlet, initiating regeneration power, and initiating regeneration flow.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 516,612, filed June 7, 2017, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to industrial electro-regenerable ion exchanges. In particular, embodiments of the invention relate to the handling of fluids in electrochemical cells, operating capacity, power supply, and cell and system designs that are particularly beneficial for deployment in large scale systems. Background technique [0004] Fluid treatment equipment including electrically regenerable ion exchange cells (ERIX cells) can be used to treat fluids to, for example, selectively exchange ions present in the fluid, remove contaminants from drinking water, reduce total dissolved solids (TDS), treat Industrial process intermediates and treatment of sewage, among other uses. An electrically regenerable ion exchange cell comp...
