  • Patent number: 11926543
    Abstract: Disclosed herein are the water clarification compositions and method of using the disclosed water clarification compositions for clarifying a water system or waste water source. Specifically, the disclosed compositions comprise and methods use multiple charged cationic or anionic compounds that are derived from polyamines through an aza-Michael addition with an activated olefin having an ionic group. The disclosed water clarification methods or compositions are found to be more effective than those methods or compositions including commonly used single quaternary compounds for reducing turbidity in water systems or waste water sources.
    Type: Grant
    Filed: February 28, 2022
    Date of Patent: March 12, 2024
    Assignee: ECOLAB USA INC.

  • Publication number: 20210403343
    Abstract: The present disclosure relates to recycling automotive phosphate rinse water. An apparatus and method is disclosed for treating process water containing phosphate. The apparatus may include a process water line. The process water line may be in fluid communication with a sample process water line. The sample process water line may be in fluid communication with a dilution line. The sample process water line, the dilution line, and a phosphate analyzer may be in fluid communication with a diluted process water line. The apparatus may also include a chemical additive feed line in fluid communication with the process water line downstream from the sample process water line.

  • Patent number: 10258683
    Abstract: Disclosed herein are single nucleic acid constructs comprising a vector, wherein the vector comprises: a first nucleic acid sequence, wherein the first nucleic acid sequence comprises one or more antigenic sequences of interest, one or more spacer sequences and one or more hydrophobic anchor sequences, operably linked to a first transcriptional control element; a second nucleic acid sequence, wherein the second nucleic acid sequence comprises one or more pathogen-associated molecular pattern (PAMP) sequences operably linked to a second transcriptional control element; a third nucleic acid sequence, wherein the third nucleic acid sequence comprises one or more cell surface receptor binding sequences operably linked to a third transcriptional control element; and a selectable marker. Also described herein, are methods of making the single nucleic acid constructs and methods of administering the single nucleic acid constructs for the treatment or prevention of infections and cancer.

  • Patent number: 9936692
    Abstract: Nanoengineered particulate coatings (NPCs) comprise a multiplicity of particulate hosts that are infused with a nanophase comprising a surfactant and at least one guest. The particulate hosts can be clay particles, the surfactant can be a cationic surfactant, and the guest can be an insect repellant. For example, montmorillonite particles infused with hexadecyl trimethyl ammonium bromide and garlic oil form NPCs that may be used to form an emulsion or suspension for spraying on citrus trees to repel Asian Citrus Psyllid.
