International Classification:
C02F 3/00, C02F 1/52
US Classification:
210608, 210150
Abstract:
The inventive water treating method and arrangement successively combine at least one step consisting in biological treating at least one part of pollution contained in said waters by a fixed biomass, wherein a bio-cleaned flow logically obtainable at the and of said step, prior to the entry thereof to a next step, contains less than 2 g/l of SS, and at least one stage for carrying out a flocculation-decantation by ballasted flocs consisting in transferring biologically treated flow to a mixing area (), preferentially at a velocity gradient ranging from 10 s−1 to 1000 s−1, wherein at least one type of denser than water insoluble granulated material is injected and suspended matters are aggregated around said granulated material particles, in transferring the flow issued from the mixing area () to a decantation area, wherein the clarified flow and decantation sludges mixed with the granulated material are separated, in extracting granulated material from the decantation sludges, in recycling major part thereof is in the mixing area () and in removing the decantation sludges separated form the granulated material.
High Rate Chemical Softening Process
US Patent:
2013031, Nov 28, 2013
Filed:
May 23, 2013
Appl. No.:
13/900575
Inventors:

Charles D. Blumenschein - Pittsburgh PA, US
Charles D. Blumenschein - Pittsburgh PA, US
Assignee:
Veolia Water Solutions & Technologies Support - Saint-Maurice
International Classification:
C02F 5/02
US Classification:
210713
Abstract:
A ballasted flocculation system that chemically softens water and causes hardness particles to precipitate from the water and crystallize. In the course of crystallizing, the hardness particles grow and form ballasted floc that are separated from the water in the form of sludge by a clarification unit, producing a clarified effluent. The separated sludge including the hardness crystals is directed to a separator where the sludge is separated into two streams with each stream having hardness crystals contained therein. In one process design, one stream includes relatively small hardness crystals and the other stream includes relatively large hardness crystals. The stream having the relatively small hardness crystals is directed to a first reactor and mixed with the incoming water and a softening reagent. The stream having the relatively large crystals is directed to a second downstream reactor and mixed with water and a flocculant which facilitates the growth of the hardness crystals.
Process For Reducing Perchlorate In Water
US Patent:
2012031, Dec 13, 2012

Assignee:
VEOLIA WATER SOLUTIONS & TECHNOLOGIES SUPPORT - Saint-Maurice
International Classification:
C02F 1/70, C02F 1/66, C02F 1/44, C02F 1/42
US Classification:
210638, 210757, 210668, 21074817
Abstract:
A method or process for removing perchlorate ions from water includes mixing water containing perchlorate ions with a reducing agent such that the perchlorate ions and the reducing agent undergo an oxidation-reduction reaction. During the oxidation-reduction reaction, perchlorate ions are reduced to chloride ions and the reducing agent is oxidized. The oxidized reducing agent is separated from the water containing chloride ions and the oxidized reducing agent is regenerated and reused in the reduction of the perchlorate ions.
Process For Removing Barium From Water
US Patent:
7608190, Oct 27, 2009

Nov 14, 2008
Appl. No.:
12/271506
Inventors:

Assignee:
N.A. Water Systems, LLC - Moon Township PA
International Classification:
C02F 3/00
US Classification:
210663, 210665, 210688, 210724
Abstract:
A method for reducing barium concentration in waste streams. Hydrous manganese oxide (HMO) is formed in solution/slurry and mixed with water containing barium such that the hydrous manganese oxide exhibits a negative charge at a desired pH. Barium from the water is adsorbed onto the negatively charged HMO surface. The HMO with adsorbed barium is separated from the water, producing treated effluent having a reduced barium concentration.
Method Of Removing Phosphorus From Wastewater
US Patent:
7828976, Nov 9, 2010
Filed:

International Classification:

US Classification:
210631, 210711, 210713, 210714, 210725, 210727, 210906
Abstract:
A process for removing phosphorus from wastewater wherein an iron or aluminum salt is added to the wastewater. The iron or aluminum salt results in the precipitation of certain iron or aluminum species that include phosphorus adsorption sites. These iron or phosphorus species are settled and become a part of sludge produced in the course of the wastewater treatment process. By recycling substantial portions of the sludge, the concentration of these iron or aluminum species in the wastewater is increased. This increased concentration results in the presence of large quantities of unused phosphorus adsorption sites that attract and adsorb phosphorus, resulting in phosphorus being removed from the wastewater.

Abstract:
A method for treating wastewater comprises biologically treating the wastewater in a fixed-biomass biological reactor and then treating the wastewater in a ballasted flocculation system. The ballasted flocculation system produces a clarified effluent and sludge containing inert granular material having biomass accumulated thereon and suspended solids. The inert granular material having biomass accumulated thereon is separated from the suspended solids and then cleaned with a cleaning solution. After separating the biomass from the cleaned inert granular material, the cleaned inert granular material is recycled for use in the ballasted flocculation system.
Regenerating Spent Pickling Liquor
US Patent:
2002000, Jan 17, 2002

Charles Blumenschein - Pittsburgh PA, US
International Classification:
C21B011/00, C23G001/02
US Classification:
134/003000, 423/150300, 134/028000, 134/109000, 134/010000
Abstract:
Apparatus and method for regenerating spent pickling liquor from the acid pickling of a metal are disclosed. Acid pickling of a metal uses a first acid and forms a spent pickling liquor (SPL). A second acid added to the spent pickling liquor, under specific low temperatures produces a metal salt of the second acid. The metal salt of the second acid is crystallized and removed from a regenerated first acid. In one aspect, hydrochloric acid is regenerated from a pickling process for iron or steel, using sulfuric acid as the second acid, and ferrous sulfate heptahydrate crystals are produced. Regenerated hydrochloric acid is recycled to the acid pickling process.
