With the improvement of domestic sewage and industrial wastewater treatment rate, the output of sludge is increasing day by day! Due to the high moisture content of sludge and poor dewatering performance, the cost of sludge follow-up treatment increases sharply. The pretreatment of sludge by physical, chemical or biological methods can change the physical properties and chemical composition of the sludge floc, destroy the colloidal structure of the sludge, reduce the affinity between the sludge and water, and thus improve the dewatering performance of the sludge. As one of chemical conditioning methods, adding chemical agents is widely used because of its simple operation and low cost.

The sludge dehydrating agents commonly used on the market now are polyacrylamide, ferric chloride, lime and so on. However, the use of these agents not only can not achieve the deep dehydration of sludge, but also a large amount. At the same time, the long-term use of these agents will also cause a certain corrosion of sludge dewatering equipment, reducing the cost of equipment. In response to the above problems, Works Chemical has successfully developed a new sludge dewatering agent through continuous independent research and development, which can effectively replace the sludge dewatering agent commonly used in the market today.

Next, Works Chemical will introduce to you, what are the functions of sludge dehydrating agents developed by Works Chemical? Why can replace the traditional sludge dewatering agent. It is a chemical agent that can change the surface structure of the sludge, reduce the surface load of the sludge solid, reduce the specific surface area of the sludge surface, and destroy the structure of bacteria. The main components are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent and so on.

The role of sludge dewatering agents:

1. The moisture content of sludge can be reduced to 40%-60%.

2. With the plate and frame filter press, it can effectively improve productivity, improve the mud press efficiency by 100%-- 500%, and reduce the mud press cycle.

3. Effectively reduce the filter cloth change frequency. 4. Add less, do not need to add lime.
