The invention aims to provide a copper mesh coated with manganese molybdate and application thereof in the separation of oil-water emulsion and degradation of organic pollutants in water. A large amount of nano-scale manganese molybdates are grown on the surface of a copper mesh through a two-step hydrothermal method. Thereby, a multifunctional composite material is prepared, which can effectively separate oil-water emulsion and degrade organic pollutants in water. The copper mesh has good recyclability. Most of all, the product is suitable for industrial production to achieve the purpose of treating water pollution.

The group of inventions relates to the field of organic chemistry and can be used for cleaning water, industrial and domestic waste water or waste water sediment, and for the containment and recovery of petroleum and petroleum product spills in large bodies of water, rivers, lakes and seas. In the claimed group of inventions, aqueous solutions of polysaccharide microgels, having a molecular mass of 20000-200000 daltons and a particle size of 50-600 nm, are used as a substance for cleaning water of petroleum and petroleum products. Moreover, low concentrations of polysaccharide microgels in water, ranging from 0.1 to 20 g/l, are used. Said solutions are used as a surface modifier for a filter used in separating water-oil emulsions, as a sorbent for the containment and recovery of oil spills in an aqueous medium, and also as a coagulant for the cleaning of water polluted by petroleum and petroleum products. The technical result is in making it possible to recover a commercial product, recovered during the process of cleaning water of petroleum or petroleum products, and to recover the starting substance for the reuse thereof, while simultaneously simplifying the slurry utilization process.

An apparatus for separating FOG from grey water in an effluent includes a housing having a first end having two plumbing fittings and a second end having one plumbing fitting. A baffle mounted inside the housing at the second end forms a barrier to flow of liquid toward the plumbing fitting on the second end above a certain height, and allows the flow of liquid past the barrier toward the plumbing fitting on the second end below the certain height. A conduit allows flow of liquid from past the baffle to one of the plumbing fittings on the first end. A plug closes one of the three plumbing fittings, and leaves the other two plumbing fittings available for connection to plumbing from a source of effluent and an outlet for grey water, respectively.

Dehydration method for a liquid or gaseous effluent selected from LPG, gasoline, diesel, kerosene, solvents and natural gases, by inserting the liquid or gaseous effluent against gravity through a drying column having a drying bed with an initial height (H+h) constituted in its lower area by an inert material bed having the height of h and in its upper area by deliquescent desiccants having an initial height of H. The deliquescent desiccants have an initial weight of between 3 and 40 g, the h/H ratio is lower than 0.49, and the inert material has a specific surface area greater than 100 m2/m3 and lower than 800 m2/m3. The method further includes separating water obtained from the liquid or gaseous effluent.

A surface containment system to contain liquid contaminates escaping from a vessel, the containment system having in one example: a water and oil impermeable barrier liner positioned below the vessel; a perimeter wall surrounding the vessel, the perimeter wall extending vertically from the ground surface and supporting a portion of the barrier liner so as to form a containment reservoir; at least one fluid conduit through the barrier liner, the fluid conduit having a filter configured to retain contaminates and configured to allow water to pass by way of gravity from the reservoir through the impermeable barrier; the perimeter wall formed of a plurality of wall panels connected by way of struts each having a vertical component, a base component anchored to ground.

A device for separating a fluid component from a fluid, in particular compressed air of a vehicle, is provided. The device has a first container for containing the fluid, the first container being arranged to separate at least a part of one or more components contained in the fluid from the fluid, and a second container, the second container being arranged to separate at least a part of one or more components contained in the fluid from the fluid.

A method of fabricating an coating includes providing a coating comprising a base material. The base material is coated with an inorganic material using at least one of an atomic layer deposition (ALD), a molecular layer deposition (MLD), or sequential infiltration synthesis (SIS) process. The SIS process includes at least one cycle of exposing the coating to a first metal precursor for a first predetermined time and a first partial pressure.
