With the continuous improvement of environmental protection requirements, the operation effect of plate and frame filter press is affected by many factors, one of which is the choice of sludge dewatering agents. So, what kind of sludge dewatering agent is good for the plate and frame filter press? Technical engineers at Works Chemical will analyze from a variety of perspectives.

First, the effect of sludge properties

The selection of sludge dewatering agents for the plate and frame filter press must first consider the nature of the sludge. In general, different sludge properties are suitable for the use of different dewatering agents. For example, for sludge with high organic content, inorganic agents such as iron oxide and aluminum sulfate can be used for dehydration; For sludge with high salt content, salt agents such as ferric chloride and sodium chloride can be used for dehydration. Therefore, selecting the appropriate dewatering agent according to the nature of the sludge is the key to improve the operation effect of the plate and frame filter press.

Second, the effect of pharmaceutical concentration

The concentration of the reagent will also affect the operation effect of the plate and frame filter press. In general, the higher the concentration of the agent, the better the dehydration effect. However, too high the concentration of the agent may lead to equipment blockage, corrosion and other problems. Therefore, it is necessary to control the appropriate concentration range when using the agent. In the specific operation, the appropriate drug concentration can be determined according to the laboratory test data or empirical values.

Third, the effect of dosage method

The dosing method will also affect the operation effect of the plate and frame filter press. Generally speaking, the continuous dosing method can maintain a certain drug effect, thereby improving the dehydration effect; And the way it's done can make it less effective. In addition, the control of the dosage of chemicals also has an important effect on the dehydration effect. Too much or too little medicine can lead to poor dehydration. Therefore, in actual operation, it is necessary to adjust the dosing method and quantity according to the actual situation.

Fourth, the effect of the mixing degree of chemicals and sewage

The mixing degree of chemicals and sewage will also affect the operation effect of the plate and frame filter press. In general, the more fully mixed the agent and sewage, the more conducive to the water molecules in the sludge to penetrate the pores in the mud cake, thereby improving the dehydration effect. Therefore, in actual operation, it is necessary to ensure that the agent and the sewage are fully mixed. The effective mixing of chemicals and sewage can be achieved by adjusting the mixing speed and mixing time.

In summary, which sludge dewatering agent is used by the plate and frame filter press depends on a variety of factors, including the nature of the sludge, the concentration of the agent, the dosing method and the degree of mixing with sewage. Therefore, in the actual operation, it is necessary to consider these factors comprehensively, select the appropriate sludge dewatering agent and carry out reasonable configuration and dosing, in order to improve the operation effect of plate and frame filter press.
