With the development of medical technology, the requirements for medical water purification are also gradually improved. From the former distillation process to the current stage of the application of reverse osmosis desalination process, we can see the progress of medical technology at the same time, the medical water purification industry is also in rapid development.
Medical water purification equipment in the application of reverse osmosis desalination process design necessity
The need for medical water purification equipment in the reverse osmosis desalination process design of the main reasons: due to the geology of our country around the country, the climate and other environmental factors are different, the formation of the quality of the water is also different; and the medical institutions on the purification of water demand, emissions and the site of the actual situation also exists. Various types of differences; therefore, according to different water quality and the hospital's own needs targeted design of special reverse osmosis desalination process.
Medical ultrapure water equipment reverse osmosis desalination process design basis
1, to the local water quality data to carry out a detailed analysis of water quality, which is to determine the design of reverse osmosis pretreatment necessary steps.
2, for the local water source characteristics of change trend analysis, which is an important basis for the rational design of water treatment system.
3, carefully confirm the analysis of water quality of purified water production of specific indicators, according to the indicators of the design of reverse osmosis desalination system components and the selection of membrane elements.
Medical ultrapure water equipment system in the reverse osmosis desalination process design of the basic process
First of all, to determine the water pretreatment program;
In order to ensure that the reverse osmosis desalination effect and the normal operation of the equipment, the design of a reasonable pretreatment program has become not to be ignored.
Secondly, the design of special reverse osmosis devices;
1, reverse osmosis devices of various types of special components selection; according to the actual water quality characteristics of the selection of suitable components type.
2, reverse osmosis device to determine the number of components; according to the required water quality standards and the required amount of water and recovery rate requirements to determine the number of various types of components and arrangement.
3, reverse osmosis device to determine the use of fittings; in order to ensure the normal operation of the device must be selected to suit the system work pressure required for high-pressure pumps, meters and valves and other necessary accessories to choose.
Third, reverse osmosis desalination post-treatment process should not be ignored;
Generally after reverse osmosis desalination of water can not be directly used in the medical process, the need for relevant post-treatment can be used in medical water.
