The application of water treatment equipment is very wide, we can often see them. Multi-medium filter as a filter equipment, has been widely used in the pretreatment of water treatment equipment, as a filter equipment, the filter effect is naturally very important, but the filter effect of multi-medium filter will be affected by many factors, so the filter effect of many media filter and what factors are related? Let's find out!
1. Temperature
When filtering, if the temperature of the filtered liquid is low, the viscosity will be larger, and the viscosity of the liquid will gradually decrease with the increase of the temperature, so increasing the temperature is a solution to the high viscosity of the liquid, but at the same time, if the temperature is too high, it will cause the oxidation of the oil, so the temperature of the gross oil filtration is usually not more than 70 degrees.
2. Operating pressure
Sometimes there will be some impurities in the filtered liquid that can not be compressed. When the working pressure is strong, the speed of filtration will become larger. If the suspended substance in the processed liquid is composed of some colloidal substances, then the gap in the filter cake will be reduced when the pressure increases, and the filtration resistance gradually increases. So the operating pressure needs to be determined according to the actual situation.
3, the concentration of the treatment liquid suspension
When the concentration is high, the filter slag will be more, the intermittent production method is used, the filtration time in each operation cycle will be shortened, affecting the actual output. For continuous operation, the filter cake produced at the high concentration is more uniform, convenient for everyone to clean in time, so the impact on the output is not very large.
4. The filter medium used
The choice of filter medium will affect the processing effect. There are many kinds of filter media that can be used in multi-media filters, but to determine which medium to use, it is necessary to see what kind of processing effect to achieve, and then to determine the filter medium that needs to be used.
This is the end of the introduction of the filtering effect of multi-medium filter and what factors are related to it. If we want to ensure the filtering effect, we should reduce the above influencing factors when filtering, and find ways to solve the impact of these factors.
