With the improvement of the treatment rates of domestic sewage and industrial wastewater, the output of sludge is increasing day by day. Due to the extremely high moisture content and poor dewatering performance of sludge, the cost of subsequent sludge treatment has increased sharply. Therefore, how to improve the dewatering performance of sludge, reduce its volume and lower the cost of subsequent sludge treatment has become an important research topic. Here, Qingdao Shijun recommends sludge enhancers.

Pretreatment of sludge through physical, chemical or biological methods can 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. Adding chemical agents as a type of chemical conditioning method is widely adopted due to its simple operation and low cost.

Nowadays, the commonly used sludge conditioners on the market include polyacrylamide, ferric chloride, lime, etc. However, the use of these agents not only fails to achieve deep dewatering of sludge, but also requires a large dosage. At the same time, the long-term use of these agents will also cause certain corrosiveness to the sludge dewatering equipment, reducing the operating cost of the equipment.

In response to the above problems, Works Chemical, through continuous independent research and development, has successfully developed a new type of sludge dewatering agent that can effectively replace the commonly used sludge conditioner on the market now. 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.

The function of sludge enhancer:

1.Sludge enhancers can reduce the moisture content of sludge to 40%-60%.

2. The sludge enhancer, in combination with the plate and frame filter press, can effectively enhance productivity, increase the sludge pressing efficiency by 100% to 500%, and shorten the sludge pressing cycle.

3. It effectively reduces the frequency of filter cloth replacement.

4. The dosage of sludge enhancer is small and there is no need to add lime.
