1. Temperature: during the operation of multi-media filter in the process of water quality treatment, if the temperature is lower and lower, the viscosity of raw water will become larger and larger, and the filtration speed of the equipment will slow down, thus making its water production efficiency lower. In the case of making the same amount of water, the time spent will increase with the decrease of temperature. The viscosity of liquid is an exponential function of temperature, which decreases rapidly with the increase of temperature. To a certain extent, heating is a simple and effective measure to reduce viscosity, and also an effective measure to speed up the production efficiency of ultra pure water.
2. Water pressure: the water quality filtration of multi-media filter needs to be completed with the help of pressure. Only under the appropriate pressure can the water have a good filtering effect. If the pressure is too small, the water yield will be reduced and the water production efficiency of the equipment will be reduced. If the pressure is too high, it is not conducive to the work of the multi-media filter. If the pressure is too high for a long time, the aging of the multi-media filter will be accelerated, and the loss of the filter material will be increased, which will increase the cost of use.
3. Content and type of impurities: the main purpose of multi-media filter is to remove all kinds of impurities in water. However, the types of impurities in water are different in different areas, and the use of multi-media filter can not remove them well. At this time, it is necessary to add certain pretreatment to precipitate the large particles in the water.
The maintenance and maintenance of the multi-media filter requires the equipment itself. The purpose of the maintenance of the multi-media filter is clear. It can timely deal with a large number of problems caused by the change of technical status in the operation process of the equipment. It can improve the technical status of the equipment at any time, ensure the normal operation, and extend the service life of the multi-media filter.
Once the multi-media filter is damaged, it usually leads to normal operation failure, so it is necessary to timely carry out regular inspection, maintenance and maintenance of the equipment. Use certain working hours for maintenance. Overhaul various parts of the equipment and pay attention to the condition of filter materials.
Special card should be set for main parts to record the place of origin, price, operation status, repair times, maintenance personnel, etc. All equipment should be equipped with enough spare parts. When it is used in winter in cold areas, special attention should be paid to the anti freezing and thermal insulation work of outdoor pipelines, gates, pumps and other equipment.
