摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A system and method of economically converting a spent first pickling acid solution that contains hydrochloric acid, water and ferrous chloride into a suitable second pickling solution. Sulfuric acid is added to the first pickling acid solution. This produces a regeneration solution. In the regeneration solution, the sulfuric acid reacts with said ferrous chloride and water to produce ferrous sulfate heptahydrate and hydrochloric acid. The regeneration solution is cooled to promote precipitation of the ferrous sulfate heptahydrate from the regeneration solution, therein creating ferrous sulfate heptahydrate crystals and a second pickling acid solution. The second pickling acid solution contains both hydrochloric acid and sulfuric acid. The ferrous sulfate heptahydrate crystals are separated from second pickling solution. The ferrous sulfate heptahydrate is sold commercially and the second pickling acid solution is used to directly pickle ferrous metal.

摘要： A method of reducing a sulfate concentration in wastewater comprises directing the wastewater stream to a precipitation reactor and mixing the wastewater stream with a calcium source and a calcium salt seed material to precipitate calcium sulfate. The precipitated calcium sulfate is then separated from a treated effluent and directed to a settling tank where the precipitated calcium sulfate is separated into heavier calcium sulfate precipitants and lighter calcium sulfate precipitants. The heavier calcium sulfate precipitants and the lighter calcium sulfate precipitants are separately recirculated to the precipitation reactor. A predetermined mass ratio of solids is maintained in the precipitation reactor.
