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.

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.

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.
