Why is it that the membrane of the small and medium-sized laboratory water purifier is blocked? Author: small and medium scale preparation of laboratory water purifier is a compact version of the device, different sized laboratory pure water and ordinary water softening equipment, this machine is mainly small and medium sized laboratory water using reverse Permeable membrane material. Its principle is that when equipment is prepared in large quantities, it is the core technology system of reverse osmosis technology and equipment. Membrane elements are an important part of environmentally friendly small and medium-sized laboratory water purifiers. The effluent quality of ultrapure water is different from that of membrane elements. When any machine is used for a long time, there will be a problem, that is, the membrane is clogged. So, why is it that the membrane of the small and medium-sized laboratory water purifier is blocked? 1. The membrane has been used for a long time. Some have been used for two, three or more years. According to the instructions, the life of the membrane is one and a half to two years. The service life of the membrane should consider the water consumption and the quality of the raw water. Water consumption and raw water quality are generally proportional to the service life of the membrane. 2. The pre-filter element has not been changed for a long time, resulting in the siltation of the water quality inside the machine, which is far worse than the water quality before entering the machine. 3. Due to the poor quality of raw water and the small proportion of concentrated water, the concentrated water solenoid valve or flushing combination valve is blocked, the machine does not discharge concentrated water or there is little concentrated water, and the membrane life is expected to be short. 4. The quality of the film itself is very poor. Some membrane element manufacturers are a bit poor, so they must choose larger factories with better quality. The above are the main reasons for the clogging of the membrane of the environmentally friendly small and medium-sized laboratory water purifier. The membrane element can be replaced in time according to the condition of the instrument.
