In order to maintain the accuracy of the effluent and protect the underlying water equipment, a security filter is required. The reasons why the filter chamber cannot be sealed are as follows:
1. Filter deformation or damage
When the edge of the filter plate is damaged, even if it is slightly protruding, even if one side is often worn, it will come into contact with other filter plates, regardless of the pressure, the formed filter chamber will be exposed. Depending on the leak point, the damage caused by the filter plate is usually large.
2. Improper placement of press cloth
The filtration chamber cannot be sealed for many reasons. We need to start with a simple method, wrapping around the filter chamber to see if the cloth is wrinkled or if the edge of the cloth is damaged. Because the structure of the filter chamber is formed by cutting the filter plate and filter cloth and relying on strong pressure, the ordinary filter plate is not a simple problem, the rest is the filter cloth. A seal should be formed between the filter plate and the key filter cloth. Wrinkles or damage to the filter cloth may create gaps between the filter plates, and the filter chamber will not form a seal.
3. Bag dust collector pressure is insufficient
The filter plate and cloth have to bear a lot of pressure to complete the closed filter chamber structure. In the absence of pressure, the pressure applied to the filter plate is less than that of the filtrate, and the filtrate will not move to produce a reasonable amount of energy from the gap.
If you want to clean the security filter, you need to shut down the system, and you can clean and unload the filter element. This will not maintain the continuity of the water supply system, affect production efficiency and greatly increase production costs. If the raw water filtration accuracy is required to be high (filtration accuracy of more than 100 microns), it is recommended that you set up an automatic sewage as pretreatment, the filter can also backwash and clean without stopping the machine, raw water through two stages of filtration, and can also ensure the accuracy of wastewater quality.
