  • Patent number: 8936726
    Abstract: Contaminants are removed from a quantity of contaminated liquid in a treatment reservoir (2,28) containing a carbon based adsorbent material capable of electrochemical regeneration. The adsorbent material is in the form of a bed supported on a plate (6) at the base of the reservoir. The bed is agitated for a period to distribute the adsorbent material in the liquid and adsorb contaminant therefrom. At the end of the period the agitation ceases, and the bed of adsorbent material is allowed to settle. The adsorbent is then regenerated, during or after settlement, by passing an electric current through the bed to release from the adsorbent gaseous products derived from the contaminant, in bubbles rising through the decontaminated liquid in the reservoir. Various methods of regenerating the adsorbent material are disclosed, as are apparatus in which the method can be applied.

    Abstract: Dried nanocrystalline cellulose (NCC), in particular films of NCC, of controlled water dispersibility and a method to control the dispersibility of dried NCC by controlling electrolyte solution ionic strength and ion valency is described. Neutral M-NCC suspensions containing monovalent counterions (e.g., M=Na+, K+, NH4+, Et4N+) produced by neutralization of acid-form NCC (H-NCC) with the appropriate hydroxide, are readily dispersible in water when fully dried; this is in contrast to H-NCC. The dispersion of dried M-NCC in aqueous media is effectively prevented by a combination of (1) increased electrolyte concentration and ionic strength, and (2) higher valency of the cation component of the dissolved salt. Additionally, pre-treatment of dried M-NCC films with an electrolyte solution having a polyvalent cation, for example a divalent or trivalent cation is sufficient to prevent the subsequent dispersion of the M-NCC film in pure water.

  • Publication number: 20110024361
    Abstract: An electrochlorination and electrochemical system for the on-site generation and treatment of municipal water supplies and other reservoirs of water, by using a custom mixed oxidant and mixed reductant generating system for the enhanced destruction of water borne contaminants by creating custom oxidation-reduction-reactant chemistries with real time monitoring. A range of chemical precursors are provided that when acted upon in an electrochemical cell either create an enhanced oxidation, or reduction environment for the destruction or control of contaminants. Chemical agents that can be used to control standard water quality parameters such as total hardness, total alkalinity, pH, total dissolved solids, and the like are introduced via the chemical precursor injection subsystem infrequently or in real time based on sensor inputs and controller set points.

  • Publication number: 20100300893
    Abstract: In some embodiments, the present invention is directed to processes for the combination of injecting charge in a material electrochemically via non-faradaic (double-layer) charging, and retaining this charge and associated desirable properties changes when the electrolyte is removed. The present invention is also directed to compositions and applications using material property changes that are induced electrochemically by double-layer charging and retained during subsequent electrolyte removal. In some embodiments, the present invention provides reversible processes for electrochemically injecting charge into material that is not in direct contact with an electrolyte. Additionally, in some embodiments, the present invention is directed to devices and other material applications that use properties changes resulting from reversible electrochemical charge injection in the absence of an electrolyte.

  • Publication number: 20100264040
    Abstract: The present invention provides a method for concentrating particles or molecules and an apparatus thereof. The apparatus comprises a substrate, a conducting granule having nano-pores or nano-channels capable of permitting ion permeation, an electrolyte solution comprising counter-ions having an opposite electric property to the conducting granule, and an external field. Wherein, particles or molecules to be concentrated have an identical electric property as the conducting granule at a predefined pH value, and are added into the electrolyte solution with the predefined pH value. While the external electric field is applied across the reservoir where the conducting granule is sitting, the counter-ions exit from the nano-pores or nano-channels and such that a transient ion super-concentration phenomenon occurs at an ejecting pole on the conducting granule so as to concentrate the particles or molecules. Hence the present invention has potential application in bead-based molecular assays.

  • Publication number: 20100038261
    Abstract: The galvanic cathodic protection of steel embedded in concrete structures is enhanced by the utilization of a flexible composite anode assembly containing a sacrificial anode member. The anode member is at least partially covered by a matrix comprising an ionically-conductive material. The conductive material includes at least one electrochemical activating agent such as a mixture of lithium bromide and lithium nitrate and a compressible water-retaining mineral such as a phyllosilicate mineral. The presence of this mineral in the matrix increases the current delivered by the anode, thereby resulting in a greater level of cathodic protection, and a longer effective service life of the anode. Exfoliated vermiculite is a preferred phyllosilicate mineral and is present in an amount of between about 2% and about 15% by weight, based on the total weight of the matrix.
