3rd period, 1985 – 1989: development of flow-through electrochemical diaphragm reactors with coaxial electrodes in the form of monoblocks
The ELHA-003 unit for producing electrochemically activated water in the processes of manufacturing printed circuit boards, electroplating and polishing of large-diameter silicon single crystals. The installation is equipped with a hydraulic system with switching the circulation circuits of the auxiliary electrolyte to any of the electrode chambers. The installation allows to obtain electrochemically activated anolyte and catholyte from deionized water with a dissolved salt content of no more than 2 mg/l. The ELHA-003 installation was designed and manufactured by V.Bahir and Yu.Zadorozhim in NGO “VOSTOK” in 1985 – 1986. Later, NPO VOSTOK mastered the serial production of installations of this type. Tashkent, 1986.Electrochemical reactor of the ELHA-003 installation. The cathode is a monoblock made of graphite MPG-6 with 19 holes for placing ceramic diaphragms and anodes made of glass carbon or ORTA with a diameter of 20 mm each. Tashkent, 1986.ECHATRON-01 installation for obtaining catholyte and anolyte from drinking water used in industrial poultry farming technologies. The installation uses an electrochemical reactor of the ELHA-003 installation with a cathode in the form of a graphite monoblock with 19 cells. The capacity of the installation is 250 liters per hour, the current is up to 100 A, the voltage is up to 70 V. Moscow, NPK ASPECT, 1989ELF-2 installation for obtaining activated anolyte and catholyte from drinking water. The installation is intended for use in the food industry and was developed according to the technical specifications of Prof. Kalunyants K.A. An electrochemical reactor with a cathode in the form of a graphite monoblock with seven cells for coaxially installed ceramic diaphragms and ORTA anodes is mounted in the installation (two photos at the bottom left). The capacity of the unit is 300 liters per hour for catholyte and 100 liters per hour for anolyte. It is equipped with a hydraulic system with switching the circulation circuits of the auxiliary electrolyte to any of the electrode chambers, which allows, if necessary, to increase the output of the anolyte to 400 liters per hour or the output of the catholyte to 600 liters per hour. In total, 20 similar installations were manufactured at ASPECT in 1989. In 1990, 15 ELF-2 units were manufactured with RPE-10L reactors from 10 PEM-1 elements created in 1989 by V.M. Bakhir. The elements of the PEM-1 are connected hydraulically in parallel using collector heads and collector plates (two photos at the bottom right)
