In the sludge treatment process, the dewatering stage is of vital importance, and choosing the appropriate chemicals is of great significance for enhancing the dewatering effect and reducing costs. Sludge enhancer, as a new type of agent, has many differences from ordinary dewatering agents and shows unique advantages.
Common dewatering agents are widely used in sludge treatment. They usually pre-treat sludge through physical, chemical or biological methods to change the physical properties and chemical composition of sludge flocs, destroy the colloid structure of sludge, reduce the affinity between sludge and water, and thereby improve the dewatering performance of sludge. However, the long-term use of these common agents will cause a certain degree of corrosion to the sludge dewatering equipment, shorten the service life of the equipment, and increase the equipment replacement cost of enterprises.
In response to these problems, a new type of sludge efficiency enhancer has been developed and produced. Sludge enhancer is a kind of chemical agent that can change the surface structure of sludge, reduce the solid surface load of sludge, lower the specific surface area of sludge, and destroy the structure of bacteria.
Sludge enhancers have multiple advantages. Firstly, it contains no chloride ions and no lime needs to be added during use. This not only avoids the potential harm that chloride ions may cause to the environment, but also reduces a series of problems brought about by the addition of lime, such as the inconvenience of lime transportation and storage as well as the potential impact on equipment. Secondly, the sludge efficiency enhancer performs exceptionally well in reducing the moisture content of sludge, capable of lowering it from over 90% to 40%-60%, fully achieving sludge reduction. This significantly reduces the treatment burden and lowers the treatment cost for subsequent sludge disposal, whether it is landfill, incineration or other treatment methods. Furthermore, sludge enhancers can significantly increase the sludge pressing rate of mechanical equipment, raising the sludge pressing efficiency by 100% to 500%, while greatly shortening the sludge pressing cycle. This means that enterprises can handle more sludge within the same period of time, improving production efficiency and increasing the economic benefits of the enterprises. In addition, the amount of sludge enhancer added is small. While achieving a good sludge reduction effect, it does not corrode the equipment. This is conducive to the subsequent resource utilization of sludge such as incineration, brick-making, and composting, which is in line with the concepts of environmental protection and sustainable development. Finally, the sludge enhancer can also reduce the frequency of filter cloth replacement for mechanical equipment. Due to its unique mechanism of action, after using this agent, the degree of clogging and wear of the filter cloth caused by sludge during the dewatering process is reduced, thereby saving the cost and time of frequent filter cloth replacement for enterprises and further reducing the operational costs of enterprises.
In conclusion, compared with ordinary dewatering agents, sludge enhancers have obvious advantages in terms of environmental protection, dewatering effect, equipment protection, production efficiency and cost savings, bringing new development opportunities and solutions to the sludge treatment industry.
