Sandwashing special flocculant is a flocculant for the selection of gravel. It is mainly used to handle the suspended solid particles in the scrubbing wastewater, and quickly condense and precipitate it, thereby achieving the separation and recycling of water from solid.
The formula of special flocculants for sand washing is usually different according to specific application requirements and processing goals. Here are some common ingredients and characteristics:
Organic flocculant: such as polymer aluminum (PAC), polymer iron sulfate (PFS), etc. These organic flocculants can form colloid impurities with the surface of the suspended particles, so that they can quickly condense and precipitate.
Silicate flocculant: such as sodium silicate (SAS), etc. Silicate flocculant has good flocculation performance and can generate stable precipitation during the processing process.
Polymer flocculant: such as cationic polyacrylamide (CPAM). The polymer flocculant has a good flocculation and precipitation effect, and the capture and precipitation of suspended objects are fast.
The use of sand washing agents is usually used to add appropriate concentrations to the gravel was washed in the scrap water, and mixed after mixing, so that the flocculant and the suspension were fully exposed. Subsequently, the wastewater was sedimentated or filtered by the sedimentation tank or filtering equipment to separate the solid particles from the water.
It should be noted that when using sand -washing coagulants, we should follow relevant safety operation guidelines and suggestions provided by manufacturers to ensure the correct use and processing waste liquid. In addition, adjust the volume and treatment process of flocculant according to the actual situation to achieve the ideal treatment effect.
