The first step in pharmaceutical water treatment equipment is the preparation of purified water system.Pharmaceutical purified water can be prepared by suitable methods such as reverse osmosis. Reverse osmosis technology is currently a relatively mature and efficient membrane separation technology. Its application in purified water equipment systems can achieve stable water production and meet the technical indicators required by the pharmaceutical industry.
The membrane separation technology used in the reverse osmosis process of pharmaceutical purified water equipment, its working principle is that when the mixture of molecules of different particle sizes passes through the semi-permeable membrane, driven by the pressure, due to the selective permeability of the semi-permeable membrane, the To achieve the separation of solute and solution. At present, reverse osmosis membrane technology has been applied and promoted in the fields of industrial water treatment, sterilization, and purification. The reverse osmosis process has more advantages than traditional filtration methods. In the traditional filtration method, when the system is running, all water passes through the filter layer of the filter, and when the filter's interception capacity drops to a certain extent, in order to effectively remove the intercepted pollutants, the backwashing operation of the equipment can be selected. When the reverse osmosis system is running, a part of the water flow in the raw water permeates the membrane along the vertical direction of the membrane surface, while the non-permeable part of the water flow flows along the parallel direction of the membrane surface, that is, the cross flow passes through, and the quality of the water is produced. More stable and reliable.
In terms of process selection, the purified water equipment adopts the reverse osmosis process and is used in conjunction with the pretreatment device. The water quality of the produced water is stable and reliable, and it has shown good results in water production projects in the pharmaceutical and other industries. If the user has higher requirements on the conductivity of the produced water, an EDI device can be installed after the reverse osmosis device to achieve deep desalination and further improve the level of water in the production process.
