Under the current backdrop of increasingly strict environmental protection requirements, domestic sewage treatment plants are under tremendous pressure to save energy and reduce emissions. The application of sludge enhancers provides an effective way for domestic sewage treatment plants to achieve this goal.

Firstly, in terms of energy consumption, traditional sludge treatment methods often require a large amount of energy. For instance, to reduce the moisture content of sludge, long-term mechanical pressing or high-temperature drying may be required, both of which consume a large amount of electrical or thermal energy. Sludge enhancers improve the dewatering performance of sludge, enabling better dewatering effects to be achieved under lower pressure or temperature conditions. Taking a large-scale domestic sewage treatment plant as an example, after using the sludge enhancer and in combination with the conventional plate and frame filter press, only a relatively low pressing pressure is needed to reduce the sludge moisture content to the ideal level, reducing energy consumption by 30% to 50% compared with before.

In terms of the use of chemical agents, traditional sludge treatment often relies on a large amount of chemical conditioning agents, such as lime and iron salts. These chemicals are not only costly but also cause a series of problems during use. For instance, the strong alkalinity of lime can lead to equipment corrosion, and iron salts can increase the volume of sludge and the difficulty of subsequent treatment. The dosage of sludge enhancers is relatively small, generally only 0.5% to 2% of the dry sludge volume. Moreover, its unique formula can avoid the drawbacks of the above-mentioned traditional agents, without the need to add a large amount of lime and other auxiliary agents, which greatly reduces the cost of using chemical agents and at the same time reduces the environmental pollution risk caused by the use of chemical agents.

From the perspective of the subsequent stages of sludge disposal, due to the better dewatering and reduction effects achieved by sludge enhancers, the energy consumption and environmental impact in subsequent disposal processes such as sludge incineration and landfill have also been correspondingly reduced. The moisture content of the dehydrated sludge is low, and the energy required for combustion assistance during incineration is reduced. Less land resources are occupied during landfill, reducing the waste of land resources and the potential risk of environmental pollution. Overall, the application of sludge enhancers in domestic sewage treatment plants, from the front end to the back end of sludge treatment, has comprehensively contributed to energy conservation and emission reduction, making significant contributions to achieving the green development goals of domestic sewage treatment plants.
