Water is an indispensable material in drug production, but drugs are special commodities related to human health, and the quality of water directly affects the quality of drugs.In recent years, with the implementation of the new version of GMP, the pharmaceutical industry has put forward higher requirements for pharmaceutical water.Among them, medical purified water equipment is used to meet the medical needs of pure water equipment, with the improvement of pharmaceutical quality requirements, high quality and high standard pharmaceutical purified water equipment has a promising future.

It is understood that the entire system of medical purified water equipment is composed of all stainless steel materials, using reverse osmosis, EDI and other new processes, can be more targeted to design a set of high purity water treatment process, to meet the pharmaceutical plant, hospital purified water production, large infusion production water requirements.

Among them, reverse osmosis is the reverse migration movement of osmosis, which is a method of separating solute from solvent in solution under pressure drive by selective interception of semi-permeable membrane.Industry insiders remind that medical purified water equipment is generally designed and produced according to the quality of raw water and the demand for water yield, so users in the selection of medical purified water equipment reverse osmosis membrane components, also should be selected according to these conditions."Only when the corresponding membrane components are selected according to the actual requirements can the expected standards be achieved. Special attention should be paid to the membrane selection."

Some users reported that when the desalination rate and water yield of the medical purified water equipment began to decrease, the system operation was not stable, and then there would be failures.Industry said that this situation may be generally caused by dirt or scale, just need to carry out a proper cleaning will not matter, users in particular need to pay attention to should be the medical purified water equipment reverse osmosis membrane failure.

So, how to "feel the pulse" of the reverse osmosis membrane failure in medical purified water equipment?A technician gave the following five steps, only for industry reference.

Step 1: the user can check the instrument to see if it is operating correctly.The correct operation of medical purified water equipment is the premise to ensure the production operation is stable and the equipment is stable without failure.

Step 2. Confirm the operation data again and check whether there is any omission or improper operation.Users can manipulate the data to exclude the above situations.

Step 3: determine if there is a problem with the equipment or a chemical malfunction.This also requires users to pay attention to the quality of equipment when selecting equipment, so as to avoid problems in the subsequent operation and bring troubles to production.

Step 4: analyze whether the failure is caused by the reaction of the chemical feed water.

Step 5: identify the pollutant and find the cause.Technicians say that if desalination rates and water production drop suddenly, and by a large margin, it is probably due to improper operation.

In addition, the technician reminds that under no circumstances should the water with free chlorine contact with the composite membrane element, or it may cause the membrane element function decline.When it is impossible to determine whether there is free chlorine, it can be verified by laboratory tests.

If the above situation occurs, the user needs to quickly solve, so as not to delay the reliable period of maintenance.In general, there are many reasons for the reverse osmosis membrane failure in medical purified water equipment, which need to be analyzed and investigated by users one by one to solve the problem.
