Even Iran has put the PCB problem “on the agenda”: a special analysis was in fact dedicated to this topic during the “POP’s management workshop” held on 9 November in Tehran. The Iranian Ministry of the Environment and Industry is currently exploring the different solutions for management (inventory, decontamination, disposal) of the PCB problem; several international operators attended the meeting, each with the task of explaining their methods for treating this POP (Persistent Organic Pollutant). It has to be remembered that “POPs are chemical compounds with toxic properties that propagate in air, water or soil and, because of their poor degradability, remain in the environment for a long time”. In this approach, 12 major pollutants: aldrin, chlordane, dichloro diphenyl trichloroethane, dieldrin, endrin, heptachlor, mirex, toxaphene, hexachlorophene and three classes of compounds: polychlorinated dibenzodioxins (PCDD, more commonly known as dioxin), polychlorinated dibenzofurans (PCDF) and polychlorinated biphenyls (PCBs) are related by action and persistence.
Sea Marconi took part in the “POP’s management workshop” in cooperation with TREDI, a French company offering complementary services to those provided by Sea Marconi. Our approach, in fact, aims at the preservation of PCB-contaminated assets through complete decontamination of oils and electrical equipment contained. The immediate advantage is that of avoiding waste production, as well as the disposal and incineration of PCBs, thus also reducing the costs of managing contaminated materials.
Sea Marconi works with its mobile units (DMU) that suck oil from the transformer and, step by step, remove PCBs from the transformer and the oil. This treatment, called CDP Process, is performed safely, on-site (even with working transformers), in a continuous, closed circuit, without even partial emptying of the transformer. Not only does the CDP Process guarantee a “PCB-free” transformer, it also brings the oil’s dielectric properties back to optimal conditions.
