A large amount of aluminum sulfate is used in water purification treatment, so it is very unrealistic to manually add medication during this process. Therefore, generally speaking, there are several ways of adding medication, namely There are three methods: gravity dosing, dosing pump and pressure dosing.
1. The gravity dosing method requires a specially constructed liquid medicine pool to be used. During use, the liquid medicine is directly put into the water under the action of gravity. This method is relatively simple, stable and reliable. . In this process, the reason why the liquid medicine pool needs to be built is to increase the height between the liquid medicines. The dosage required when using it is not very large, and when transporting the liquid medicine, it needs to be The pipeline is controlled within a relatively short range.
2. There is also a method of pressure dosing, which mainly creates a negative pressure at the position of the nozzle under the action of high-pressure water, and then inhales the medicine and injects it into the pressure water pipe. In this way, aluminum sulfate needs to be used The equipment is relatively simple, and there is no need to build a very high liquid tank for use. However, this method is relatively inefficient when used, even when adding There may also be clogging due to improper operation, but this method can be used in purification processes of all sizes.
3. When the dosing pump is used, it only sucks the medicinal liquid directly into the medicinal liquid pool, and then inhales it into the pressure tube for quantitative dosing. However, the price of the equipment required for dosing using this method is high. It is relatively high, but the pump may easily become clogged during use, which will also be more troublesome during later maintenance.
The above introduces several common ways of dosing aluminum sulfate when using it. In fact, these three ways of dosing are not good or bad, but they have different advantages and disadvantages. , so we also need to choose the appropriate dosing method based on the actual usage.
