MOSCOW. April 20 (Interfax-AVN) - The Russian Armed Forces will soon be supplied with new water-purification filters, which can be used on the battlefield and during emergency- and disaster-relief operations, an official from the Defense Ministry's 15th Central Research and Development Institute, told Interfax-Military News Agency on Wednesday.
"The new NF-50 man-portable water-purification filter and the NF-10V individual water-purification filter have been designed at the request of the Russian Defense Ministry," the official said.
He noted that man-portable water-purification filters, designed in the 1980s and fielded in the 1990s, had expired their service lives. In addition to that, they no longer meet water-purification requirements, since the list of substances polluting water has considerably increased and water-purification standards have become considerably tougher.
Man-portable filters are designed to purify water from water bodies and wells of dredges, bacteria, viruses, poison, and radioactive substances.
Man-portable filters can be used both on the battlefield, and during emergency- and disaster-relief operations, the official pointed out.
The NF-50 filter purifies water in two ways - water chlorination, and diaphragm purification, which in its turn comprises mechanical purification, sorption, and microfiltering.
