How to solve the problem of pipe blockage caused by polyaluminium chloride

In industrial wastewater treatment, Polyaluminium Chloride (PAC) is widely used as a highly effective coagulant in precipitation and clarification processes. However, when using polymeric aluminum chloride, the problem of excessive water insoluble matters may lead to pipe blockage. This paper will discuss this problem in detail and propose a solution accordingly.

In the process of industrial wastewater treatment, polymerized aluminum chloride sometimes leads to the problem of pipe blockage. On the one hand, it may be due to the operator’s improper operation, and on the other hand, it may be due to the quality of the polymeric aluminum chloride itself, such as the high content of water-insoluble matter. In order to ensure the smoothness of the wastewater treatment process, it is necessary to take appropriate measures to solve the problem for different reasons.

Selection of high-quality poly aluminum chloride

High-quality PAC should have the characteristics of low content of water-insoluble matter and few impurities, and so on. Excessive water-insoluble matter is the key factor causing pipe blockage. If the production process fails to properly select raw materials and deal with the water-insoluble matter and the content of water-insoluble matter is high, PAC users may find the phenomenon of pipe blockage after using for a period of time. This not only affects the treatment effect but also may cause huge economic losses. Therefore, when purchasing polymerized aluminum chloride, you can not just pursue the cheap price but should choose reliable quality products.

Adopt the correct use method

Before using polymerized aluminum chloride, the solid should be fully dissolved in a ratio of 1:10. If dissolved insufficiently, the solution with undissolved solids will easily clog the pipes. In order to ensure the dissolving effect, you need to fully understand the dissolving ability of the dissolving equipment and choose the appropriate mixing equipment. In addition, when you find solid particles sinking to the bottom, you should take timely measures to avoid clogging.

Solution: Tackling clogged pipes

In order to avoid the frequent occurrence of pipe clogging phenomenon, you should pay attention to the following issues:

Install filters in front of the pump and check and change them frequently; increase the diameter of the pipe to reduce the possibility of clogging; increase the pipeline flushing equipment so that it can be flushed when clogging occurs; maintain a suitable temperature to avoid crystallization under low temperature; employs spring-loaded poppet valves to ensure that the solution is ejected into the water with sufficient pressure to reduce the risk of clogging.

In addition, there are some additional suggestions to help prevent the occurrence of pipeline blockage problems: do not try to choose cheap and poor quality products; pay attention to the dilution ratio of the product to ensure full dissolution; regular inspection and cleaning of pipeline equipment to prevent the formation of crystallization and precipitation.
