When sludge dewatering agent (sludge conditioner) replaces lime in sludge dewatering treatment, the moisture content can indeed be significantly reduced. This is because the sludge dewatering agent can effectively improve the dewatering performance of the sludge, so that the sludge is easier to remove water during the press filtration process.
Compared with lime, sludge dehydrating agent has the following advantages:
Efficient dewatering: sludge dewatering agent has a strong dewatering ability and can quickly combine with the water in the sludge to form a hydrate that is easy to remove. This allows the sludge to remove water more quickly during the press filtration process, achieving a significant reduction in water content.
Environmentally friendly: Lime may produce dust pollution and waste disposal problems during use, while sludge dehydrating agent is more environmentally friendly. They do not produce harmful substances during use, and the treated sludge can be more easily used or disposed of later.
Simple operation: The use of sludge dehydrating agent does not require complex operation processes, which can reduce the labor intensity of the staff. At the same time, sludge dehydrants usually have a long shelf life and stability, easy to store and use.
Reduce the cost: Because the sludge dewatering agent can improve the dewatering effect of the sludge, reduce the cost of subsequent treatment. At the same time, because there is no need to use inorganic salts such as lime, the corrosion and maintenance costs of the equipment can also be reduced.
In practical applications, sludge dehydrating agents have successfully replaced traditional sludge dehydrating agents such as lime, and have been widely used in many fields. For example, a sewage treatment plant uses a new type of sludge conditioner instead of lime for sludge dewatering treatment, and the results show that the moisture content of the sludge is reduced from the original 65% to 60%, which greatly improves the sludge dewatering effect. At the same time, the treated sludge has no secondary pollution, and the environmental load is effectively reduced. After a long period of operation, the sewage treatment plant found that the cost of using the new sludge conditioner was reduced by about 30% compared with the traditional lime method, which saved a lot of costs for enterprises.
