The dosage of polyaluminium chloride(PAC) is very important. Controlling the dosage well can achieve many advantages such as good use effect, small dosage and low cost. Some customers are very careless in use. Add one bag to see if it works. If not, add one more bag. This is very wrong. It is easy to cause excessive or insufficient use of polyaluminum chloride, The correct way to cause unqualified effluent is to buy back a batch of polyaluminium chloride, take an appropriate amount of sewage, make a small test with the prepared polyaluminium chloride liquid, calculate the dosage through the small test, and then add it according to the obtained dosage, which can not only save the dosage of polyaluminium chloride, but also ensure the qualified sewage discharge, Therefore, controlling the dosage of polyaluminium chloride is the key in the use process.
