Sludge conditioner plays a crucial role in solving the problem of non-forming plate and frame press mud. The following is a detailed analysis of how sludge conditioners solve this problem:
1. The reason why the plate and frame press mud are not formed
Sludge properties: sludge contains a large number of colloidal particles and impurities, resulting in poor flocculation effect, difficult to form a stable filter cake. At the same time, the hydrophilicity of the sludge is too strong, making the water difficult to be effectively removed.
Equipment problems: the plate and frame filter press may have problems such as blockage and rust of the filter plate during use, which affects the filter press effect.
Operating conditions: Unreasonable setting of filter press parameters, such as filter press time, pressure, etc., may lead to poor cake formation. In addition, if the sludge is not fully pre-treated and dried, it is also easy to lead to insufficient dehydration, resulting in high sludge moisture content and non-forming problems.
2. Mechanism of action of sludge conditioner
Sludge conditioner is a chemical agent that can change the surface structure of sludge, reduce the surface load of sludge solids, and destroy the structure of bacteria. It mainly solves the problem of non-forming plate and frame mud by the following ways:
Change the properties of the sludge: the sludge conditioner can destroy the colloidal structure of the sludge, making it easier to form floc. At the same time, it also reduces the hydrophilicity of the sludge, making the water easier to remove.
Improve the flocculation effect: by adding the sludge conditioner, the flocculation effect of the sludge can be significantly improved, making it easier for the sludge particles to gather into larger clumps, which is conducive to the filtration and pressing of the filter press.
Reduce the moisture content of filter cake: sludge conditioner can improve the dewatering performance of sludge and significantly reduce the moisture content of filter cake. This can not only improve the efficiency of sludge treatment, but also reduce the cost of subsequent treatment and disposal.
Selection and application of sludge conditioner
Selection principle: When selecting sludge conditioner, factors such as the nature of sludge, treatment needs and subsequent disposal methods should be fully considered. At the same time, it is also necessary to pay attention to the cost of the conditioner, the amount added and the impact on the environment.
Application method: The sludge conditioner usually needs to be added before the sludge enters the filter press and is fully mixed evenly. The amount added should be adjusted according to the nature of the sludge and treatment needs to achieve the best dewatering effect.
Note: When using sludge conditioner, it is necessary to follow the relevant operating procedures and safety specifications. At the same time, it is also necessary to regularly maintain and maintain the filter press to ensure its normal operation and filtration effect.
4. Case Sharing
In practical applications, many sewage treatment plants have successfully used sludge conditioners to solve the problem of non-forming plate and frame press mud. For example, the sludge conditioner (sludge enhancer) independently developed by Qingdao Shijun New Materials Co., Ltd. has been widely used. These sludge conditioners can not only effectively improve the dewatering efficiency of the plate and frame filter press, but also significantly reduce the moisture content of the filter cake, so as to realize the harmless and reduced treatment of the sludge.
In summary, the sludge conditioner has a significant effect on solving the problem that the plate and frame press mud is not formed. By selecting the right sludge conditioner and applying it correctly, the dewatering efficiency and treatment quality of sludge can be significantly improved, the cost of subsequent treatment and disposal can be reduced, and greater contributions can be made to the cause of environmental protection.
