A large slaughterhouse wastewater treatment plant in Paraná, Brazil, was experiencing poor sludge dewatering due to the high concentrations of proteins, fats, and organic matter in its biological sludge. The existing polymer resulted in high sludge moisture, long filtration cycles, and increasing ...
The Application of Polyacrylamide in High-Salinity Wastewater Treatment In high-salinity wastewater treatment, polyacrylamide (PAM) is primarily used as a flocculant during the pretreatment and sludge dewatering stages — not for directly removing salinity. The high-salt environment can significan...
As the world grapples with escalating water scarcity and stringent environmental regulations, the polyacrylamide (PAM) industry stands at the forefront of sustainable solutions. Jiangsu Hengfeng Fine Chemical Co., Ltd., a premier manufacturer of high-quality PAM powder and emulsion, has emerged as a ...
A textile dyeing factory located in Rayong experienced serious sludge dewatering problems in its plate-and-frame filter press system after expanding production capacity. The sludge generated from the DAF and physicochemical treatment systems contained high levels of surfactants, dye residues, and ...
A municipal wastewater treatment plant recently faced challenges in its sludge dewatering system, where belt filter press performance had declined, resulting in high sludge moisture, excessive polymer consumption, and unstable cake formation. By introducing Hengfeng Cationic 9802 and optimizing the ...
Hengfeng PAM test- Electronic factory wastewater Electronic manufacturing wastewater exhibits distinct characteristics primarily due to complex chemical processes involved. Its key features include: l Elevated Heavy Metal Content: Contains significant concentrations of toxic heavy metals such as ...
Machining wastewater, generated from cutting fluid, cleaning agent and grinding fluid production, features "Three Highs and One Difficulty": high COD from refractory emulsified oil, high suspended solids with metal powder, high toxicity containing heavy metal ions (Cr, Ni), and extreme water quality ...
Jiangsu Hengfeng Fine Chemical Achieves Major Breakthrough in Customized Electronic Factory Wastewater Treatment Solution Recently, the customized wastewater treatment solution tailored by Jiangsu Hengfeng Fine Chemical Co., Ltd. (hereinafter referred to as "Jiangsu Hengfeng") for an electronic ...
A large textile dyeing factory recently upgraded its Dissolved Air Flotation (DAF) system to improve wastewater clarification performance. However, shortly after commissioning, the flotation system experienced unstable sludge separation, high effluent turbidity, and frequent scraper blockage. By ...
