A treatment process of persistent organic pollutants contained in particles is provided. Said process includes reacting persistent organic pollutant in particles under hydrothermal conditions in the presence of Fe2+ and Fe3+. Several beneficial effects can be achieved, including 1) no other additive is needed during the reaction process; 2) Fe2+ and Fe3+ are safe, cheap and extensive sources; 3) because Fe2+ and Fe3+ are dissolved, they can fully disperse into particles, and fully contact can be achieved, thus obtaining a decomposition rate no less than 70% of the persistent organic pollutants is under subcritical conditions.

The invention relates to a so-called zero emission ‘AST-CNR/ITM system’ modular plant for removal of pollutants from flue gases produced by industrial processes. The plant comprises prefabricated modular elements with programmed and automatic operation, easy to mount and assemble on site without undergoing expensive plant stoppage. Each module or ‘reaction tower’ comprises a plurality of sections vertically arranged on top of one another, which carry out the following functions: Removal of particulate matter with treatment and removal of chemical pollutants, such as heavy metals, chlorides, fluorides Treatment and removal of SOx Treatment and removal of NOx Capture of CO2 Production of hydrogen Production of methanol. The various sections may be combined according to the requirements of the plant and of the flue gases to be treated.

A device for extraction of pollutants by multichannel tubular membrane containing at least one fluid channel allowing the fluid to go through a feed inlet to an outlet end characterized in that membrane comprises at least an extraction channel filled with molten salt in order to adsorb said pollutants having to be extracted from the said fluid. Advantageously, the membrane is a ceramic membrane. An application is for the treatment of traces of pollutants in a liquid or gaseous fluid. For example, the removal of small pollutants as volatile organic compounds from an aqueous stream in industrial wastewater treatment or other water treatment applications, or the separation of aromatic compounds form an hydrocarbon feed in petrochemical applications. Another application is in the removal of water traces in products of high added value as pharmaceutical, cosmetic or biocarburant for example.

The present invention is directed to a degradation composition, methods and kits for degrading organic pollutants comprising reduced copper based nanoparticles-polymer complex (Cu-NPs) and an oxidant.

The Hon’ble court after observing reports given by various technical authorities like the Varadharajan Committee and The Central Board for the prevention and Control of Water Pollution, held that the emissions generated by the coke/coal consuming industries are air-pollutants and have a damaging effect on the Taj and the people living in TTZ. The court directed the atmospheric pollution generated in TTZ to be eliminated and the industries to use natural gas as an industrial fuel and those industries who are not in a position to obtain gas connections to relocate themselves.

DNREC announced it has successfully used an innovative approach to reduce polychlorinated biphenyls (PCBs) in two Delaware waterways.

In Delhi, the comparison made from the second week of March (before lockdown) to first week of April (April 6), reduction in PM2.5 was found to be by 62 per cent, PM10 by 57 per cent and NOx by 50 per cent,  the latest SAFAR data accessed by PTI showed.

A self-powered device that generates electricity from the wind can also absorb and break down harmful nitric oxide and nitrogen dioxide from the air

BP Products North America Inc. has agreed to pay a $15 million penalty to resolve federal Clean Air Act violations at its Texas City, Texas, petroleum refinery.

John Tuma, 55, of Centerville, Texas, was sentenced today following his March 21, 2012, trial conviction by a federal jury for discharging untreated wastewater directly into the Red River without a permit, discharging untreated wastewater into the city of Shreveport sewer system in violation of its permit and obstructing an EPA inspection.

New report paints a worrying picture, provides recommendations on what can be done.

About 40 percent of homes in America have a gas stove, but a new report reveals the appliance may be bad for your health. They can cause cancer in adults and asthma in children.
