HENGFENG A1655 PAM Excels in Bunker Wastewater Treatment
Recently, through professional and repeated laboratory tests, Jiangsu Hengfeng Fine Chemical Co., Ltd. has achieved groundbreaking results in vessel bunker wastewater treatment with its optimized flocculant formula. The product exhibits excellent and stable treatment performance in laboratory verification, pioneering a new technical method for bunker wastewater treatment with PAM reagents in the industry.
Bunker wastewater is one of the most difficult treatment types in marine environmental protection. It contains high concentrations of emulsified fuel oil, fine suspended particles and stable colloids, forming a highly stable oil-water emulsified system. Conventional water treatment chemicals struggle to break the emulsified structure, often resulting in fine and loose flocs, slow sedimentation speed and turbid treated water, which cannot meet standard discharge requirements. Such complex working conditions put forward extremely high demands on the oil resistance, adaptability and flocculation efficiency of water treatment agents.
To break through the industry technical bottleneck, Hengfeng’s professional technical team designed targeted laboratory simulation tests according to the actual water quality characteristics of bunker wastewater. After repeated formula debugging and parameter optimization, a scientific two-step treatment process was finalized: PAC dosing first, followed by Hengfeng A1655 anionic polyacrylamide. In the first stage, PAC (Polyaluminum Chloride) performs charge neutralization, effectively destroying the stable colloidal and emulsified oil system in the wastewater, and forming tiny initial alum flocs. In the second stage, Hengfeng A1655 anionic PAM plays a powerful bridging and adsorption role. Its long molecular chains can rapidly adsorb and aggregate the scattered tiny flocs into large, dense and solid floccules.
This professional combined process realizes the rapid separation of oil stains, suspended solids and water. The flocs settle quickly without floating, the supernatant is clear and transparent, and the separated sludge is compact, which greatly facilitates subsequent sludge dewatering and disposal. Compared with single-agent treatment, this solution features higher purification efficiency, simpler operation and stronger adaptability to fluctuating water quality.
Multiple repeated laboratory tests have verified that the combined process of PAC and Hengfeng A1655 anionic PAM features stable treatment effect, reasonable and controllable chemical dosage, and high purification efficiency. It perfectly solves the long-standing industry problem of poor treatment effect of conventional chemicals on bunker wastewater. Most importantly, this research achievement **creates a precedent for the application of PAM in bunker wastewater treatment**, breaking the technical limitation that traditional water treatment reagents are difficult to adapt to high-oil marine wastewater, and filling the industry technical blank of PAM applied in vessel bunker sewage treatment.
As a professional R&D and manufacturing enterprise of polyacrylamide flocculants, Jiangsu Hengfeng Fine Chemical has a complete product system including anionic, cationic and non-ionic PAM. With reliable product quality and mature technical services, the company’s products are widely used in marine oily wastewater, industrial sewage, mineral processing, sand washing and other water treatment fields.
Different from ordinary generic PAM products, Hengfeng A1655 anionic PAM is specially optimized for high-oil and complex water quality environments. It maintains excellent bridging flocculation performance under severe oil interference, with strong resistance to water quality fluctuations, which is the core advantage in marine bunker wastewater treatment.
This successful laboratory test fully verifies the superior performance and innovative value of Hengfeng A1655 anionic PAM in complex high-oil wastewater treatment, marking a major breakthrough in the application of polyacrylamide products in the marine environmental protection field. In the future, Jiangsu Hengfeng Fine Chemical will continue to focus on the research and development of high-efficiency and environmentally friendly water treatment chemicals. Based on this pioneering research achievement, the company will further optimize product formulas and technical processes, accelerate the transformation from laboratory research to industrial and on-site practical application, and provide innovative, reliable and cost-effective water treatment solutions for the global marine environmental protection industry.
