Liquid Purification Or Separation > Processes > Making An Insoluble Substance Or Accreting Suspended Constituents > Including Oxidation > Of Iron Or Manganese Material Of Iron Or Manganese MaterialOf Iron Or Manganese Material patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.04/26/07 - 20070090057 - Process for the purification of acidic metal-bearing waste waters to permissable discharge levels with recovery of marketable metal products Acidic metal-bearing wastewaters are treated to produce a finished water of sufficient purity to meet discharge standards while recovering metals removed in forms which are commercially valuable. The metals are selectively precipitated, either in a batch or in a continuous system, for removal of individual metal products in a specific ... 10/19/06 - 20060231498 - Reactive filtration In one embodiment, a method for removing a contaminant from alkaline water includes adding ferric iron to alkaline water until reaching a pH less than 7 to form a neutralized solution and exposing the neutralized solution to iron metal. ... 10/05/06 - 20060219640 - Method for handling waste material generated in a metallurgical process The invention relates to a method for improving the filterability and washing result of fine-grained waste material generated in the metallurgical industry. According to the method some of other fine-grained solid is added to the first waste precipitate before filtration, which is also removed from the process, and which remains ... 07/13/06 - 20060151398 - Iron composite particles for purifying soil or ground water, process for producing the same, purifying agent containing the same, process for producing the purifying agent and method for purifying soil or ground water Iron composite particles for purifying soil or ground water, comprise α-Fe and magnetite, and having a ratio of a diffraction intensity D110 of (110) plane of α-Fe to a sum of a diffraction intensity D311 of (311) plane of magnetite and the diffraction intensity D110 (D110/(D311+D110)) of 0.30 to 0.95 ... 03/23/06 - 20060060539 - Method for treating at ambient temperatures acid or non-acid mine drainage waters containing heavy metals using recirculated iron oxide as an oxidation and precipitation catalyst The present invention is to provide a method for treating Acid Mine Drainage (AMD) or Non-Acid Mine Drainage (NAMD) waters, exhibiting a relative acidity/alkalinity pH factor of from 5.0 to 10.0, containing one or more of the heavy metals Fe, Mn, Mg, Al, Cu, Ni, Cr, or Zn held in ... 02/16/06 - 20060032821 - Treatment of iron contaminated liquids with an activated iron solids (ais) process The present invention is a method and system for treating iron-contaminated water (e.g., mine drainage) using an innovative treatment approach identified herein as the Activated Iron Solids (AIS) Process. The AIS process is capable of oxidizing and removing iron as iron oxides from iron-contaminated waters (such as, mining-related discharge, groundwater, ... 01/19/06 - 20060011553 - Water purification system and method An oxidation filtration system for cleaning groundwater, the system having an aeration tower and a filtration tank. Within the filtration tank is an upper chamber and a lower chamber. Contained within the lower chamber is a plurality of Styrofoam™ filter media. Separating the upper chamber from lower chamber is a ... 12/15/05 - 20050274678 - Integrated technology in sequential treatment of organics and heavy metal ions wastewater This invention offers an integrated technology in sequential treatment of wastewater. Low biodegradable organics and heavy metal ions are both contained in wastewater from surface finishing processes. The aim of the invention is to find the solution for treatment of organics and heavy metal ions in complicated wastewater that contains ... ### FreshPatents.com Support |
