1、 Introduction

Due to the current fine processing of minerals, the solid-liquid separation of the formed slurry is relatively difficult, often resulting in phenomena such as inability to filter, inability to dry, compact filter cake, high water content, and the need for a shovel frame. Today, the technical engineer of Shijun New Materials will explore how to improve the dewatering efficiency of the plate and frame filter press by using sludge conditioning agents.

2、 The role of sludge conditioning agents

The main function of sludge conditioner is to change the physical and chemical properties of the material, reduce the resistance of water, make it easier for the material to pass through the filtering medium, and thus improve the dewatering efficiency. Common sludge conditioning agents include silicates, polyacrylamide, etc.

3、 How to choose and use sludge conditioning agents

Choosing the appropriate sludge conditioner is a key step in improving dewatering efficiency. Organic conditioners mainly promote sludge flocculation and sedimentation by changing the surface charge properties and adsorption of sludge;

Inorganic conditioning agents mainly change the physical properties of sludge through chemical reactions, making it easier to dehydrate. During use, it is necessary to regularly check the performance of the sludge conditioner, such as pH value, viscosity, etc., to ensure that it is used under appropriate conditions.

4、 Determine the amount and method of adding sludge conditioning agents

Determine the amount and method of addition based on the properties of sludge and dewatering requirements. Generally speaking, the dry dosing method for sludge conditioner involves directly adding the conditioner to the sludge, while the wet dosing method involves mixing the conditioner with water before adding it to the sludge.

5、 Debugging and optimization of sludge conditioning agents

During the use of sludge conditioning agents, parameters such as the pressure of the filter press, the speed of the filter cloth, and the porosity of the filter cloth can be adjusted to achieve the best dewatering effect. It should be noted that the amount and method of use of sludge conditioning agents need to be adjusted according to the actual situation. Improper use may have a negative impact on the dewatering effect of sludge.
