Polyaluminum and polyferric
Thread Content
What to do if precipitation occurs in polyaluminum and polyferric compounds? Is there any way to avoid it?
What you’re saying is too general; it’s confusing at first glance. First of all, in the processing stage you’re referring to, what kind of equipment is used there, and what processing standards must that equipment meet? Your question above is like saying: I’m full. Who is full? Eat what will fill them. . . . .
Polyaluminum chloride and polyferric chloride are generally used as coagulants. I suspect the owner has a dosing tank; after the coagulant is prepared, sediment forms at the bottom of the tank (possibly due to some of it not dissolving), which can easily cause blockages at the outlet. We use stirring while the power is on (air blowing can also be used if conditions permit), stirring continuously to keep it in a suspension state.
What LZ is asking is whether sedimentation occurs when polyaluminum and polyferric compounds are used as coagulants in the dosing system; this can be addressed by using stirring, or, if possible, by introducing factory air from the bottom to keep them in a suspended state
I understand what the original poster means; that’s something that cannot be avoided. Even if you use transparent products. It can be stirred during configuration, and then physically removed on a regular basis. Furthermore, it is necessary to buy good quality medicines with minimal impurities.
It is best to install the chemical feed pump inlet not at the very bottom of the chemical tank, and to clean the tank regularly
The function of a flocculant is to aggregate small particles into larger ones, thereby facilitating faster sedimentation.
