In the process of sewage treatment, the excessively high moisture content of sludge has always been a difficult problem plaguing the industry. Excessively high moisture content not only increases the volume and weight of sludge but also raises the costs of subsequent treatment and transportation. The emergence of sludge enhancers has provided an effective solution to this problem.

Sludge enhancer is a kind of chemical agent specifically used to improve the dewatering performance of sludge. It releases more free water by altering the charge properties and structure on the surface of sludge particles, making the bonding between sludge particles tighter. In this way, the water in the sludge can be separated more easily, thereby significantly reducing the moisture content of the sludge.

Compared with traditional sludge dewatering methods, the use of sludge enhancers has many advantages. First of all, its operation is very simple. Just add the reagent to the sludge in a certain proportion, and after simple stirring and reaction, the ideal dewatering effect can be achieved. Secondly, the sludge enhancer has a remarkable effect. It can reduce the moisture content of sludge to a relatively low level in a short time, greatly improving the dewatering efficiency of sludge. Moreover, the use of sludge enhancers can also reduce equipment wear and energy consumption, and lower treatment costs.

Effect advantage

Youdaoplaceholder0 Reduce moisture content ‌ : In combination with the plate and frame sludge press, the moisture content of sludge can be reduced from over 90% to 40% - 60%, fully achieving sludge reduction. The original moisture content of papermaking sludge, which was as high as 80% to 90%, can be reduced to below 60% after treatment. This significantly reduces the volume of the sludge and lowers the cost and difficulty of subsequent treatment.

Youdaoplaceholder0 Enhance dewatering efficiency ‌ : It can improve the dewatering performance of sludge and significantly increase the dewatering efficiency of dewatering equipment such as plate and frame filter presses and belt filter presses. Within the same period of time, more sludge can be processed, which improves the operational efficiency of the entire sludge treatment system. Some enterprises introduced sludge enhancers for experiments and found that the operational efficiency of dewatering equipment increased by more than 30%.

Youdaoplaceholder0 Improve sludge properties ‌ : After being treated with sludge enhancers, the sludge has more stable properties, is less prone to putrification and odor, which is conducive to the storage and transportation of sludge and also provides better conditions for subsequent resource utilization, facilitating subsequent resource utilization such as incineration for power generation or fertilizer production.

Youdaoplaceholder0 Other advantages ‌ : less dosage and lower cost of the reagent; It does not contain chloride ions and does not require the addition of lime. The addition amount is small, the sludge volume is significantly reduced, and it does not corrode the equipment. It can reduce the frequency of filter cloth replacement for mechanical equipment and save the operating costs of enterprises. A matching accelerator can be pre-added for the subsequent sludge drying and disposal process, which greatly improves the efficiency of the subsequent drying and disposal.

In practical applications, many sewage treatment plants have adopted sludge enhancers to reduce the moisture content of sludge. For instance, before a certain sewage treatment plant started to use sludge enhancers, the moisture content of the sludge had always remained above 80%. Even after dewatering treatment, the volume of the sludge was still very large, and the transportation and treatment costs remained high. After the application of sludge enhancers, the moisture content of the sludge rapidly dropped below 60%, the volume of the sludge was significantly reduced, and the transportation and treatment costs were also notably lowered.

Sludge enhancers do have a set of methods in reducing the moisture content of sludge. With its simple operation, remarkable effect and low cost, it has become an ideal choice for sewage treatment plants to solve the problem of excessively high moisture content in sludge.
