FEM-1 Flow-Through Electrochemical Module Cell

FEM-1 cell, 1989

The Electrochemical treatment of water and device for electrochemically treating water.

British patent GB 2 253 860. Claimed on 12.03.91, published on 23.09.1992. Authors: V.M.Bakhir, Yu.G. Zadorozhny.

FEM-1 аlow-through electrochemical module cell. FEM-1 module was developed by V. M.Bakhir and Yu. G. Zadorozhny in 1989, and its first models were made and tested in the same year. FEM-1 module played an important role in developing a new approach to engineering and technology for producing electrochemically activated water and solutions. It was not widely used in industry due to complexity of collector head manufacture and a number of problems associated with the formation of bi-polar segments of cathode electrode surface, but indicated an optimal principal way of de-veloping commercial electrochemical systems. Combined with the auxiliary electro-lyte capacity operated under elevated pressure FEM -1 module was firstly employed in the first modification of STEL-МТ-1 device meant for producing washing, disinfectant and sterilizing solution – anolyte of neutral рН value. Development of the device was carried out in conformity with Russian Health Ministry assignment: it started in Octo-ber 1990, and was completed in June 1992. The diagram was later described in the British patent GB 2 253 860. Preparation for the development of STEL-МТ-1 device consisting in working out and full-scale production of FEM-1 module had been per-formed at the VNIIIMT MZ RF by V.M.Bakhir and Yu.G. Zadorozhny since1989.

Electrochemical unit of STEL-МТ-1 device.

The device’s electrochemical reactor consists of one FEM-1 cell. In 1990, STEL-МТ-1 device was approved by the USSR Ministry of Health for commercial manufacture and wide application in medical facilities. The device’s output is 20 l/h of neutral anolyte (AN), consumed electric power is 100 W
