Patent number: 11926543Abstract: 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: GrantFiled: February 28, 2022Date of Patent: March 12, 2024Assignee: ECOLAB USA INC.Inventors: Ashish Dhawan, Carter M. Silvernail, Aarthi Narayanan, Jason Robert Burney

Patent number: 9936692Abstract: 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.Type: GrantFiled: February 14, 2013Date of Patent: April 10, 2018Assignee: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.Inventors: Parvesh Sharma, Aarthi Narayanan, Hassan E.
