Hello, everyone, recently, WorksChemical Xiaobian received a customer consultation asking how to remove water from the sludge most quickly? Today, the technical engineers of WorksChemical are here to reveal the secrets.

First, chemical agents can be used to remove water in the sludge:

1. Lime: It is a kind of sludge dewatering agent, but too much use can lead to serious corrosion of equipment.

2. Polyacrylamide/polyaluminum chloride: as a sewage flocculant, mainly based on flocculation.

3. Sludge conditioner (sludge dehydrating agent) : After dewatering the sludge, the sludge volume increment is small, and the mud cake volume is increased by 1.05-1.20 compared with that of the absolute dry sludge, which is 50% lower than that of the traditional lime method, and the subsequent treatment cost is low and the treatment efficiency is increased.

Second, mechanical equipment can be used to remove the water in the sludge:

High pressure diaphragm plate and frame filter press: suitable for deep dewatering of sludge in various industries. Simple operation and high efficiency.

Screw stacking machine: suitable for sludge with high organic composition content.

Belt filter press: suitable for small and medium-sized sewage treatment plants and industrial wastewater treatment plant sludge, high organic content of the sludge, the treatment effect is better.

Centrifugal dewatering machine: suitable for the treatment of high concentration sludge (such as sludge concentration tank and digestion tank), can achieve faster dehydration.

Third, hot dry method can be used to remove the water in the sludge

Hot dry dehydration is the use of heat energy to vaporize the water in the sludge, so as to achieve the purpose of dehydration. Common methods of hot dehydration include drying and incineration. The thermal dewatering method can reduce the moisture content of sludge to a very low level, but the energy consumption is high and the operation cost is high.
