In the field of sewage treatment, plate and frame filter presses, as a common solid-liquid separation device, are widely used in sludge dewatering treatment. However, in the actual operation process, plate and frame filter presses often encounter the problem of unformed sludge, which not only affects the dewatering efficiency but also increases the difficulty and cost of subsequent treatment. This article will deeply analyze the reasons for the non-formation of sludge in plate and frame filter presses and recommend an effective solution - a new type of deep conditioning agent, sludge enhancer.
The reasons why the sludge pressed by the plate and frame filter press is not formed
The failure of the plate and frame filter press to form formed sludge is usually related to multiple factors such as the nature of the sludge, the operating parameters of the filter press, and the use of chemicals. Specifically, it mainly includes the following aspects:
Youdaoplaceholder0 Sludge properties : The moisture content, particle size, organic matter content and other properties of sludge directly affect the filtration effect. If the moisture content of the sludge is too high, the particles are too fine, or the organic matter content is relatively high, it may all lead to the sludge not being formed properly.
Youdaoplaceholder0 operating parameters : The operating parameters of the filter press, such as pressure, pressing time, and feeding speed, also have a significant impact on the filtration effect. If the parameters are not set properly, such as insufficient pressure, too short pressing time or too fast feeding speed, it may lead to the mud not being formed properly.
Youdaoplaceholder0 Chemical agent usage : During the sludge dewatering process, some chemicals are usually added to improve the dewatering performance of the sludge. However, if the agent is improperly selected or the addition amount is insufficient, it may also lead to the mud not being formed properly.
Sludge enhancer: An effective solution to the problem of unformed sludge pressing To address the issue of unformed sludge in plate and frame filter presses, it is recommended to use sludge enhancers as a solution. Sludge enhancer is a kind of chemical agent specifically designed to improve the dewatering performance of sludge. It can enhance the dewatering efficiency of sludge by altering its particle structure and reducing its viscosity, thereby solving the problem of unformed sludge during pressing.
Advantages of sludge enhancer :
Youdaoplaceholder0 Enhance dewatering efficiency : Sludge enhancers can significantly reduce the moisture content of sludge, improve dewatering efficiency, and make the sludge cake after filtration more compact and easier to handle.
Youdaoplaceholder0 Reduce the dosage of chemicals : Compared with traditional dewatering chemicals, sludge enhancers have higher efficiency, can reduce the dosage of chemicals added, and lower treatment costs.
Youdaoplaceholder0 environmentally friendly and harmless : The sludge enhancer adopts an environmentally friendly formula, which is harmless to the environment and meets the requirements of sustainable development.
Youdaoplaceholder0 Easy operation : The application method of the sludge enhancer is simple. Just add it to the sludge in a certain proportion, without the need for a complex operation process.
When the sewage treatment plant was using the plate and frame filter press for sludge dewatering treatment, it encountered the problem that the pressed sludge was not formed. After analysis, it was found that it was caused by the poor nature of the sludge and the improper selection of chemicals. The factory introduced sludge enhancers and added them to the sludge in accordance with the recommended proportion. After a period of operation, it was found that the mud cake after filtration was significantly more compact and easier to handle, and the dewatering efficiency was also significantly improved. Meanwhile, due to the high efficacy of the sludge enhancer, the dosage of the agent has been significantly reduced, lowering the treatment cost.
