Osmotron Inject of Christian Water Technology Group

Although in the industry WFI usually by distillation one produces, diaphragm procedures permit cost savings of factor 5.5 to 7.5 in the comparison to distillation depending upon quantity. Highly Purified Water, which can be won by reverse osmosis in combination with electrode ionization and an osmose stage or an ultrafiltration downstream, offers therefore a clear economic advantage. The in such a way produced water quality corresponds to the WFI in its chemical and physical characteristics in accordance with USP. In Europe the procedure for the production can be used by HPW in accordance with EP. For injection and infusion solutions produced WFI is prescribed in Europe however further by distillation. With the Osmotron Inject offers the high-purity water specialist to Christian, member the Christian Water Technology Group, a plant for the HPW production by means of double reverse osmosis and electrode ionization.The compact unit is completely sanitisierbar with hot water and represents such a safe, closed system. With applications, which demand an integrity test, appropriate material can be used in the ultrafiltration. Also with this procedure combination the soft water in a first process step reaches the reverse osmosis stage after passing the safety filter under high pressure. The majority of the water flows through the diaphragm and leaves thereby the solved materials; it leaves the Permeator with a remainder salt content of approximately two per cent. In the next step the Permeat flows by the patented, temperature-stable Christian electrode ionization module Septrosan, where it is completely demineralized. The treatment works beyond that pyrogenreduzierend as well as due to very high pH gradients of pH 2 to pH 12 extremely germ-reducing. Reverse osmosis or ultrafiltration represents the last process step.If an integrity test is demanded, in principle an ultrafiltration stage is used. Their likewise sanitisierbares hollow fiber module is completely emptyable and exhibits a separating characteristic (MWCO) of 6.000 Dalton. In addition its offer and, the dead-space-poor structure completely cast in in synthetic resin highest security to doubly asymetrischen diaphragms. As a check of the ultrafiltration modules these are concentrate-laterally emptied and a compressed air pad is put on. A defective module is recognizable from ascending bubbles on the filtrate side. Also under economic criteria the ultrafiltration exhibits a plus: It permits a 100%ige to water yield. Just as the plant concept with reverse osmosis downstream produces also this Osmotron Inject variant water quality, which clearly falls below the limit values of USP 27 and EP 5. The conductivity reaches a value of about 0.1 µS/cm and a TOC content of smaller 20 ppb.The relevant micro-biological values are to less than 0.06 EU/ml with less as 5 KBE/100 ml and. The high-purity water plant covers a power spectrum of 500 to 10,000 litres per hour; also customized configurations for larger flow rates are possible. The Osmotron Inject consists of the material 316 L, orbital welded with a Oberflaechenrauigkeit of caption: The Osmotron Inject for the production from 500 to 5,000 l/h high-purity water is available in two configurations: with a combination of double reverse osmosis and EDI module as well as with reverse osmosis, EDI module and ultrafiltration downstream.
