Patent number: 11535537Abstract: A method for efficiently removal of oxidised selenium from liquid, such as FGD wastewater. The method involves adding a non-iron-based reducing agent (e.g. sodium dithionite) and preferably Fe(II) ions to the liquid at a pH of above 7.5 or 8 and precipitating elemental selenium from the liquid.Type: GrantFiled: October 26, 2015Date of Patent: December 27, 2022Assignee: Ecolab USA Inc.Inventors: Tarun Kumar Bera, Jitendra T. Shah, Vaideeswaran Sivaswamy

Patent number: 10626750Abstract: Disclosed are methods useful in applications relating to blast furnace processes. The methods of the present invention provide enhanced deposition inhibition of particulate matter in top-pressure recovery turbines. The methods of the present invention comprise adding nitrogen-containing compounds to a top-pressure recovery turbine, inhibiting deposition of solids formed from blast furnace gas on top-pressure recovery turbine components.Type: GrantFiled: December 8, 2017Date of Patent: April 21, 2020Assignee: Ecolab USA Inc.Inventors: Tarun Kumar Bera, Fan Yang, Jiaqi Zhang, Glenn L. Scattergood, Roger W. Fowee

Patent number: 10358363Abstract: Novel fluorophores and their use as fluorescent tags for polymers used in wastewater treatment. The fluorophores are quaternary amine salts that can be used to synthesize fluorescent tagged polymers that are stable at varying pH, have significant water solubility, and may be fluorescent at wavelengths greater than 550 nm. The fluorophores readily undergo polymerization with vinylic monomers to form fluorescent tagged polymers with excellent incorporation of fluorophore into the polymer framework. The fluorescent tagged polymers are useful to monitor and optionally dose industrial wastewater.Type: GrantFiled: March 17, 2016Date of Patent: July 23, 2019Assignee: Ecolab USA Inc.Inventors: Tarun Kumar Bera, Deepak Jadhav, Kiran Phatangare, Trishul Artham, Jitendra Shah, Wesley Lamar Whipple, Winston Su, John David Morris, Paul Joseph Zinn

Patent number: 10301205Abstract: The present disclosure relates to a formulation and a process for the removal of inorganic impurities from waste water. The formulation consists of a blend of at least one alkali metal aluminate, at least one cationic organic coagulant and optionally at least one alkalinating agent in pre-determined proportions. The process for decontamination using the afore-stated formulation includes steps such as admixing, settling, microfiltration and optionally acidification, ultrafiltration and reverse osmosis. The disclosure further provides an apparatus for the removal of inorganic impurities from waste water.Type: GrantFiled: February 17, 2015Date of Patent: May 28, 2019Assignee: ECOLAB USA INC.Inventors: Tarun Kumar Bera, Manish Kumar Singh, Yogesh Bhole

Patent number: 10000393Abstract: Dewatering agents and methods of dewatering wastewater slurries are provided. Also disclosed are methods for improving the separation of solids from water. The water may be produced water, raw water, or wastewater, for example. The dewatering agents can be in solutions and the dewatering agent solutions may include various components in addition to soy protein, soy flour or a combination of soy flour and soy protein.Type: GrantFiled: January 14, 2015Date of Patent: June 19, 2018Assignee: ECOLAB USA INC.Inventors: Prasad Y. Duggirala, Weiguo Cheng, Darlington Mlambo, Tarun Kumar Bera, Luiz Wanderley Bratfisch Pace
