Many friends who have used it or have experience in water treatment know that polyacrylamide is an organic flocculant, while polyaluminum chloride is an inorganic coagulant. But can these two flocculants be used simultaneously? What would the effect be? Many people must have this question. Today, Henan Saike Environmental Protection will answer it for all new and old customers.
When treating wastewater, it is difficult to achieve the customer’s required effect by using only one flocculant. However, if polyacrylamide and polyaluminum chloride can be used simultaneously, it can solve the wastewater problem very simply. Speaking of this, some customer friends are eager to rush to conduct experiments. Don’t be in a hurry. There is still a little knowledge here, that is, the order of addition and the interval time. Polyaluminum chloride PAC is a coagulant and reacts with the wastewater very quickly. After adding, it needs to be fully and strongly mixed. While polyacrylamide PAM is a flocculant and cannot be mixed too vigorously to avoid destroying the already formed flocs. So, in normal circumstances, it should be added polyaluminum chloride PAC first and then polyacrylamide PAM. However, to be on the safe side, it is still recommended that everyone conduct small-scale experiments to determine the final dosing sequence. The interval time of dosing, the proportion of dosing, the amount of dosing and the intensity of mixing all require a rigorous and scientific experiment. Do not mix the two agents directly, otherwise it will directly affect the wastewater treatment effect and increase the cost.
