Washing appliance with dedicated water-softener

Номер: US20120298153A1
Автор: Gene Sidney Shelp, Iurie Pargaru, Leonard Paul Seed
Принадлежит: ENPAR TECHNOLOGIES INC

The softener is based on a capacitive-deionization (CDI) cell, in which the hardness ions are extracted, and disposed of still intact, in concentrated form. The softener is combined with a chelate to inhibit precipitation, in the appliance, from the concentrated effluent. The chelate being citric acid, the acidity is effective to keep the hardness ions in solution. The purify and regenerate modes of operation of the softener can be timed to coincide with the washing and rinsing cycles of the appliance, whereby the presence of the softener does not affect the speed and performance of the appliance.

Methods for the treatment of ballast water

Номер: US20130056648A1
Автор: II Richard W. Fahs, Matthew D.W. Fahs
Принадлежит: Fahs Stagemyer LLC

A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. This process can be used for the remediation of water, particularly ballast water.

A blend of micro-crystals of magnesium ammonium phosphate and other seed materials with magnesium hydroxide slurries reduces struvite scale in wastewater collection systems leading into waste-water treatment plants. These “seeds” act as attractants to phosphates and ammonia to allow the seeds to grow and remain dispersed throughout the waste water system. This greatly minimizes, or prevents struvite scale from building up in unwanted areas such as pipes, pumps, and valves that could potentially cause water flow blockage.

Polyphenol-type polymer coating of filtration membranes

Номер: US20130240445A1
Автор: Kristof Vizvardi, Zoltan A. FEKETE
Принадлежит: General Electric Co

A filtration membrane is coated with a polymer made from a compound comprising a benzenediol or a substituted phenol, such as catechol. The polymer deposition process comprises exposing the membrane to the compound in an aqueous alkaline solution. A membrane module may be immersed in the solution. Optionally, the solution is aerated. The polymer coating is reasonably durable in aqueous environments but may be removable. In an example, a module of PVDF based outside-in hollow fiber membranes was coated with poly(catechol). The membranes had a reduced fouling rate and could be maintenance cleaned with water or a dilute oxidant solution. The polycatechol coating could be oxidized by cleaning the membrane with a hypochlorite solution and re-coated. The modified membranes may be used, for example, in water or wastewater treatment. A filtration process includes steps of oxidizing and re-applying the coating after the membrane has been in use.
