1. Properties of flocculant itself
Before purchasing polyaluminum chloride, we should fully understand the properties and characteristics of polyaluminum chloride. In the process of use, we usually prepare a solution. The liquid prepared on the same day should be used up on the same day. Long storage time will greatly affect the flocculation effect. Users should pay attention to this during use.
2. Product dosage
When adding polyaluminium chloride, we must determine the optimal dosage through small experiments. When users buy polyaluminium chloride, some manufacturers will remind users that polyaluminium chloride manufacturers will carefully do display experiments for customers to determine the dosage and calculate the cost. Why should we determine the optimal dosage? Because too much or too little polyaluminium chloride will affect the flocculation effect.
3. PH value of sewage treatment
When treating sewage, the first thing to do is to test the pH value of sewage and adjust the pH value of sewage to a good range suitable for polyaluminium chloride, generally between 6.0-9.0, so that the sewage treatment effect is good. Ignoring this step will also affect the flocculation effect of polyaluminium chloride.
4. Temperature of treated sewage
I don’t know if you have noticed. Due to the difference of seasonal temperature in spring, summer, autumn and winter, the flocculation effect is also different when polyaluminium chloride is used. The flocculation effect is often poor when the temperature is low in winter, so temperature is also one of the factors affecting the flocculation effect.
5. Mixing speed and time
Mixing speed and time are small details, which are often ignored by users. Details also need to be paid attention to. Too fast or too slow mixing speed can affect the flocculation effect. The same is true for the length of mixing time. Therefore, some small details also need to be paid attention to and implemented.
