Abstract: A method is provided for removing an inorganic ionic species or organometallic ion contaminant, or combination contaminants, including such as arsenic, chromium, bromide, bromate, perchlorate, and/or others from water which contains an unacceptably high concentration of the contaminant(s). The method includes treating the water with an ion exchange resin, preferably a magnetic ion exchange resin such as MIEX® Resin, which is capable of adsorbing the inorganic ionic species contaminant(s), and regenerating and recycling the ion exchange resin back to the process. The method produces potable water from ground water containing such contaminants and eliminates breakthrough and chromatographic peaking problems observed with conventional ion exchange systems.
Abstract translation: 提供了一种用于从含有不可接受的高浓度污染物的水中去除无机离子物质或有机金属离子污染物或组合污染物的方法，包括诸如砷，铬，溴，溴酸盐，高氯酸盐和/或其它物质的混合污染物， 。 该方法包括用离子交换树脂处理水，优选是能够吸附无机离子物质污染物的MIEX树脂等磁性离子交换树脂，并将离子交换树脂再生并再循环回 的过程。 该方法从含有这些污染物的地下水中产生饮用水，并消除了常规离子交换系统观察到的突破和色谱峰值问题。

Abstract: Dispersed solid materials in aqueous waste waters are agglomerated for easier filtering by adding a polyelectrolyte, a floc former and a filter aid in any order in which the filter aid is present for incipient floc formation. The electrolytes exemplified are branch chain amines, quaternary ammonium or sulphonium salts. The floc formers exemplified are tri- and tetravalent metal salts and the filter aids exemplified are diatomaceous silica, perlite, or non-organic fibre.

Abstract: Provided are electrochemical devices that are rechargeable, where the regeneration techniques are based on a batchwise application of current or current density to the cells, where there are a service mode where no current or current density is applied and a recharge mode where a current or current density is applied. Electrochemical and EDI systems according to the embodiments herein are suitable for deionization and/or purification of typical municipal tap quality water in applications where demand for purified, low-TDS water is intermittent. Such operations avoid the use of chemical additions for regeneration purposes. In addition the cells provided herein are amenable to small footprints for consumer and commercial applications such as: dishwashers, washing machines, coffee and espresso makers, ice makers, steam tables, car wash water sources, and steamers.

Abstract: The present invention relates to water treatment, in particular to a process for the removal of dissolved organic carbon from water. The process includes the following steps, adding an ion-exchange resin to water containing a contaminant such as dissolved organic carbon, dispersing the resin in the contaminated water to enable adsorption of the dissolved organic carbon onto the resin, and separating the resin loaded with contaminant from the water. In a preferred embodiment the process employs a magnetic ion-exchange resin.
