Sludge additive (sludge conditioner) is an efficient product designed to solve the problems of mud cake thin and runny in the sludge treatment process. The following is a detailed analysis of how sludge enhancers (sludge conditioners) specifically solve the problem of mud cake thin and runny:
First, the principle of sludge synergist (sludge conditioner)
Sludge enhancer (sludge conditioner) is usually a modified polymer product with multiple functions that can play an important role in the deep dewatering process of sludge. Its main principles include:
Enhance the cohesion of the sludge particles: the sludge synergist (sludge conditioner) can react with the solid particles in the sludge, so that it forms a larger floc, thereby enhancing the cohesion and sedimentation of the sludge.
Improve dewatering efficiency: By improving the dewatering performance of the sludge, the sludge synergist (sludge conditioner) can speed up the dehydration rate and improve the dryness and thickness of the mud cake.
Reduce filtrate residue: sludge enhancer (sludge conditioner) can reduce residual substances in the filtrate, reduce the turbidity and suspended matter content of the filtrate, and improve the quality of the effluent.
Second, sludge synergist (sludge conditioner) to solve the mud cake thin, runny problem of the specific performance
Increase the thickness of mud cake: After the use of sludge synergist (sludge conditioner), due to the enhanced cohesion of sludge particles, the formation of mud cake is more thick, which effectively solves the problem of mud cake thin.
Improve the degree of mud biscuit: sludge enhancer (sludge conditioner) can significantly improve the dryness of mud cake, so that the moisture content of mud cake is lower, to achieve better dehydration effect.
Eliminate the phenomenon of semiliquid: The phenomenon of semiliquid is mainly due to the incomplete dehydration of sludge or the uneven distribution of internal water. Sludge enhancer (sludge conditioner) can improve the dewatering performance of sludge and make the dryness inside and outside the mud cake more uniform, so as to effectively eliminate the phenomenon of runny.
3. Practical application cases
Taking a municipal sewage treatment plant as an example, the original plan of the plant adopted polyacrylamide pretreatment, but there were some problems, such as complicated conditioning process, serious waste of chemicals, large proportion of conditioner in the mud cake, high metal content in the filtrate, too long time for board and frame to enter the mud and press the mud cake, slow dehydration speed and easy to produce "runny" phenomenon. Later, the plant used a new type of sludge enhancer (sludge conditioner) to replace the traditional conditioning process, and achieved remarkable results:
Stable operation, saving 30% processing cost.
The whole operation is automatic and does not change the pH value of the sludge.
Thoroughly solve the filter plate and pipe fouling tendency.
The thickness and dryness of the mud cake after pressing and filtering can increase the production.
It does not produce solid waste due to conditioning and reduces the cost of solid waste treatment.
Fourth, the selection of sludge synergist (sludge conditioner) precautions
Product performance: Select sludge synergist (sludge conditioner) with high dewatering performance, low residue and no effect on sludge properties.
Scope of application: According to the type of sludge and treatment process to select the appropriate sludge synergist (sludge conditioner).
Cost effectiveness: Considering the cost and benefits of sludge enhancer (sludge conditioner), choose cost-effective products.
Supplier qualification: Select suppliers with good reputation and qualification to ensure product quality and after-sales service.
In summary, sludge enhancer (sludge conditioner) is an effective means to solve the problems of mud cake thin and runny in the sludge treatment process. The efficiency and quality of sludge treatment can be significantly improved by selecting the appropriate sludge enhancer (sludge conditioner) and using it correctly.
