Cationic Coagulant Polyamine is a high-efficiency liquid cationic organic coagulant widely used for industrial wastewater treatment. Featuring high cationic charge density, it quickly neutralizes negatively charged dye molecules, colloids and fine suspended solids, delivering outstanding decolorization performance for textile, printing and papermaking wastewater. It can effectively remove chroma, SS and colloidal COD, helping factories meet discharge standards and support water reuse.
Different from inorganic coagulants such as PAC and ferric salts, polyamine works stably over a wide pH range of 4–10, less sensitive to fluctuation of wastewater quality. It generates far less sludge without introducing metal ions into effluent, greatly cutting sludge disposal costs. As a liquid product, it is easy to dilute and dose, with fast reaction speed to form compact micro-flocs. It can be used alone or combined with PAC and anionic PAM to improve solid-liquid separation.
It is also suitable for RO membrane pretreatment to reduce SDI and mitigate membrane fouling. Our Decolorization Chemical polyamine series has stable quality and multiple specifications to match different water conditions. We provide factory direct supply and professional technical support for jar test and on-site formulation optimization. Contact us for quotation.
