Abstract: Compositions for water treatment are provided. In some embodiments, the composition comprises: a cationic polyacrylamide-type polymer having a charge density of about 10% to about 40% and a molecular weight of about 600×104 g/gmol to about 900×104 g/gmol; and a cationic surfactant, the surfactant comprising an alkyl quaternary ammonium salt. Also provided are related methods and kits for treating wastewater with dispersed and dissolved organic matters and oils. Embodiments of the compositions, methods, and kits can be used to treat oil-in-water emulsions, produced water, and process water containing dispersed and/or dissolved organic matter such as hydrocarbons from various process industries including Steam Assisted Gravity Drainage (SAGD) oil operations.

Abstract: The present invention describes a device for assessing and providing quality feedback on thoracic compressions during cardiopulmonary resuscitation, which allows for an optimal assessment of the quality of the thoracic compressions made during cardiopulmonary resuscitation, which provides feedback on the position of said compressions. The device for assessing and providing quality feedback on thoracic compressions during cardiopulmonary resuscitation, by means of the elements thereof together with essential technical features thereof, such as an infrared sensor, a microprocessor, logic means, a graphic interface and remote connectivity means, makes it possible to estimate the depth and frequency parameters of the thoracic compressions, in order to determine whether they are adequate during a cardiopulmonary resuscitation procedure.

Abstract: A charged particle polymer hybrid (CPPH) flocculant is taught, comprising sub-micron size charged particles and a polymer which has been polymerized in the presence of the charged particles wherein the intrinsic viscosity of the hybrid polymer flocculant is less than 930 ml/g. A method is provided for producing freely draining flocculated sediment from a suspension comprising finely divided solids in water. The method comprises dispersing, at increasing concentrations, a charged particle polymer hybrid (CPPH) flocculant into the suspension to determine a starting plateau concentration of CPPH flocculant above which concentration no further increase in the solids loading of the produced floccules is observed. Then, the concentration of dispersed CPPH flocculant in the suspension is maintained at or above the starting plateau concentration. A method is further provided for separating fine solids and water from a suspension comprising finely divided solids in water.

Abstract: A method is taught for producing freely draining flocculated sediment from a suspension comprising finely divided solids in water. The method comprises dispersing, at increasing concentrations, a charged particle hybrid polymer (CPHP) flocculant into the suspension to determine a minimum concentration of CPHP flocculant above which a freely draining flocculated sediment is produced that has a minimum permeability of 1 Darcy. Then, the concentration of dispersed CPHP flocculant in the suspension is maintained at or above the minimum concentration. A method is further provided for separating fine solids and water from a suspension comprising finely divided solids in water. The method involves dispersing, at increasing concentrations, a charged particle hybrid polymer (CPHP) flocculant into the suspension to determine a minimum concentration of CPHP flocculant above which a freely draining flocculated sediment is produced that has a minimum permeability of 1 Darcy.
