During the long development process of sludge treatment, traditional methods once dominated. However, with the continuous improvement of environmental protection requirements and the steady progress of technology, sludge efficiency enhancers, as a new treatment method, have gradually demonstrated advantages that are completely different from traditional methods.

In traditional sludge treatment methods, lime-assisted dewatering is relatively common. Lime is strongly alkaline and can rapidly reduce the water content of sludge through coagulation, while increasing the weight of sludge, which is convenient for subsequent treatment. However, this method has many drawbacks. Firstly, the use of lime will cause the pH value of sludge to rise sharply, often exceeding 12. Such a high pH value will not only seriously corrode the treatment equipment, shorten its service life, but also cause the filter cloth to clog, affecting the filtration effect. Secondly, the excessive addition of lime will significantly increase the amount of sludge, usually by 30% to 50%, which undoubtedly adds to the burden of subsequent treatment. Moreover, due to the addition of lime, the calorific value of sludge decreases, which imposes restrictions on subsequent resource utilization methods such as incineration and brick-making. From a cost perspective, the amount of lime used is large, usually reaching 30% to 50% of the dry sludge volume, which keeps the cost of chemical agents high. Meanwhile, the use of lime also requires the installation of dedicated dust removal equipment, which increases the complexity and cost of the operation. In addition, the filtrate after lime treatment is strongly alkaline and requires additional neutralization treatment, further increasing the overall cost.

In contrast, sludge enhancers have many obvious advantages. In terms of dewatering effect, the sludge enhancer, through its unique component combination, such as the cell wall breaker to release intracellular water, combined with electro-neutralization and flocculation effects, can reduce the water content of sludge from over 90% to 40%-60%, and in some cases even reach 54.27%-61.35%. Moreover, the volume of sludge cakes can be reduced by more than 50%, significantly lowering transportation and disposal costs.

From a cost perspective, the dosage of sludge enhancers is only 0.5% to 2% of the dry sludge volume, and the cost of treating each ton of sludge can be as low as 5 to 15 yuan.

In terms of environmental performance, the pH value of the sludge enhancer is controllable, generally around 8.0, and there are no residual chloride ions. This not only avoids corrosion to the equipment but also eliminates the need for secondary treatment of the filtrate, making it more environmentally friendly.

In terms of operation and equipment compatibility, sludge enhancers also perform well. During its operation, the automatic shedding rate of the sludge cake is high. For instance, in the case of Hebei, the sludge cake even needs to be held down with a shovel to prevent it from falling off too quickly. Meanwhile, the cleaning frequency of the filter cloth can be reduced by more than 50%. Moreover, the sludge enhancer can be deeply coordinated and cooperated with equipment such as plate and frame filter presses and centrifuges. Combined with high-pressure pressing (1.0-1.4MPa), the pressing time can be shortened by 30%-50%.

In a comprehensive comparison, sludge enhancers outperform traditional sludge treatment methods in terms of dewatering effect, cost control, environmental protection performance and operational convenience.
