Water purification has developed numerous specialised water treatment agents tailored to specific sectors within the water purification industry. Today we present:
polyacrylamide specifically formulated for coal washing plants, referred to within our factory as our coal washing speciality product. As the name suggests, this polyacrylamide agent for coal washing plants undoubtedly offers distinct performance advantages for coal washing applications. Utilising PAM with a molecular weight ranging from approximately 8 million to 18 million. When applied to coal washing wastewater, polyacrylamide rapidly enhances flocculation efficiency. This treatment addresses the substantial sludge content in coal wastewater, accelerating sedimentation to achieve water purification. The precipitated coal particles can be recovered for reuse, indirectly reducing purification costs while preventing secondary environmental contamination.
In the current coal washing plant water purification process, the primary treatment method employs flocculation followed by sedimentation. During this procedure, polyacrylamide and polyaluminium chloride are selected for their complementary action, achieving superior purification results. This accelerates the settling of particulate matter, enhancing coal washing efficiency and increasing the plant's processing capacity, with excellent treatment outcomes. For coal washing plant effluent treatment, anionic polyacrylamide is predominantly employed. However, selection must be tailored to the specific characteristics of the wastewater, as impurity compositions vary. Consequently, cationic polyacrylamide and non-ionic polyacrylamide may also be utilised. How then should one select the appropriate polyacrylamide grade for coal washing plant effluent treatment? What are the key performance characteristics?
Prior to employing polyacrylamide in coal washing plant effluent treatment, samples of the wastewater must first be taken. Through beaker testing, the optimal polyacrylamide grade and most suitable dosage can be determined.
Advantageous properties of polyacrylamide agents specifically formulated for coal washing plants:
- Rapid dissolution with no insoluble residues; dissolution time is approximately one hour.
- Rapid formation of large flocs. Flocs are substantial and densely packed, enabling swift sludge settling to the reactor tank base.
- Low dosage requirement, resulting in reduced purification costs. Delivers excellent water quality improvement with straightforward operation.
- Strong filtration performance and superior sludge dewatering capability.
- Capable of automated dosing, significantly reducing operator workload.
