The filter element is the core of the filter and assumes an important part of the overall process, but many factors will affect the use of the filter during using it directly. Let's take a look at the directly effect of the use of stainless steel filter element.
1.The organic content of the filter medium:
There are many areas use the stainless steel filter. So there are many kinds of filter media to be carried out. Some of which are organic substances in some filter media and even some bacteria in the medium such as water, oil, too much organic matter. Triggering the propagation of organic digestive bacteria and ammonia nitrogen in the biofilm competition of in the growth of space that dissolved oxygen and nutrients and oxides. Thus affecting the filtration effect.
For example, when the ratio of biochemical oxygen demand (COD) to ammonia nitrogen ratio is greater than 2.7, the removal rate of ammonia nitrogen will decrease by about 70% when filtering water.
2. The PH and alkalinity of the filter medium:
Different pH of the filter medium is different, while the stainless steel filter itself can prevent corrosion, acid-base uneven environment will often corrode the filter layer, which will greatly reduce the filter effect.
Since the fixed-mode filter element is dependent on the diffusion of material to work, the convective mixing between the fixed film and the water has a great effect on its working efficiency. The experiment shows that the appropriate mixing of the filter medium will effectively increase the ammonia nitrogen Removal rate.
3. The temperature of the filter medium:
It is generally believed that the temperature of the filter medium will also affect the role of the filter. In the process of filtering the stainless steel filter, the reaction temperature of the partial filter medium itself is high. But the fact is that if the temperature changes slowly within a certain range the ability of the bacteria to adjust the temperature, so that the efficiency of the filter will not have a greater impact.
