Recently, many people have been interested in reverse osmosis membranes, old membranes, do you know these points? I am more interested, in order to meet everyone's needs, let's talk about it, if you are interested, you can learn about it.
The main purpose of the old reverse osmosis membrane is to realize the utilization and resource utilization and reduce the negative impact on the environment. The following is a brief introduction to the selection, replacement and ** of the old reverse osmosis membrane:
1. Selection: When choosing a reverse osmosis membrane, it is necessary to consider factors such as water quality composition, water treatment needs, and membrane performance requirements. Common reverse osmosis membrane materials include polyethersulfone (PES), polyamide (PA), etc., and suitable materials and models can be selected according to the specific situation.
2.Replacement: The reverse osmosis membrane will gradually decay during use, resulting in a decrease in water treatment effect. When the permeability of the membrane element decreases to a certain level, it needs to be replaced. The specific way to replace a reverse osmosis membrane is to remove the old membrane first, then put the new membrane on, and ensure the correct connection and sealing.
3.The processing of old membranes can be done in two ways: physical and chemical. Physical** is mainly to clean and disinfect the old film and then reuse it. Chemistry is the decomposition of membrane materials through specific chemical treatment methods, and the useful components in it.
When using the old film, the following points need to be noted:
Cleaning: The cleaning process requires the use of appropriate cleaning agents and processes to remove dirt and deposits from the membrane surface.
Detection: Before the first test, the old film needs to be tested to evaluate its residual permeability and damage degree to determine whether it is suitable for use.
Treatment: According to the material and nature of the old film, select the appropriate treatment method, such as physical separation, chemical treatment, etc.
Reuse: The old membranes after ** treatment can be reused, e.g. for the preparation of new reverse osmosis membranes or other related materials.
For the selection, replacement and treatment of the old reverse osmosis membrane, it is necessary to make reasonable selection and treatment according to the specific situation to achieve the goal of resource utilization and environmental protection.
