Described is a process for treatment of a fluid comprising an oxidizable contaminant selected from one or both of a sulfide and a thiol, the process comprising the step of contacting the fluid with a first complex of ferric iron and a polyphosphate to oxidize the oxidizable contaminant and generate a second complex of ferrous ion and the polyphosphate.

A treatment method for a used ion exchange resin, includes: bringing a used ion exchange resin into contact with a reaction solution, the used ion exchange resin having an ion exchange group with at least a radionuclide or a heavy metal element adsorbed thereon, and the reaction solution containing an iron compound, hydrogen peroxide, and ozone; separating at least a part of the reaction solution in contact with the used ion exchange resin from the used ion exchange resin; and decomposing an organic component contained in the reaction solution separated from the used ion exchange resin.

A pH-stable dye which allows the penetration of hydrochloric acid into amorphically different carcinogenic fibers used for detection of sprayed asbestos or plastic mineral fibers for fireproofing components, is proposed. In the process, the continuous colored penetration of the fiber layers is achieved synchronously with the decomposition process of the hydrochloric acid. Thus, the progress of the penetration process can be estimated during the reconstruction work, and the task of removing the now spongy layers can be carried out with contrast agents of the following group consisting of organic and inorganic substances such as acridine orange, brilliant cresyl blue, bromophenol blue, eosin Y, erythrosine B, fluorescein, methyl blue, methyl orange, thymol blue resulting in the even penetration of carcinogenic fibers using hydrochloric acid.

A secured smart container is disclosed for collecting green waste products including operational functions for collection, video surveillance and monitoring capacity. The secured smart container may include one or more programmable logic controllers. Operational functions are performed by electrical components including sensors to determine green waste deposits characteristics and contents. Operational functions are further adapted to send and receive data, operationally wirelessly, and configured and adapted to utilize solar derived electric power and, optionally, electric power from other sources. Embodiments provide constant 24 hour/7 days a week video surveillance and alert monitoring capabilities. Disclosed systems and methods also include collection and transportation of waste contents from the container to a processing subsystem. Additionally, disclosed systems may also include a monitoring system for monitoring the collection of green waste product, delivery of the same to the processing subsystem and tracking to and throughout final processing of the green waste product and handling personnel.
