A novel coagulant, polyferric(III)-magnesium(II) sulfate (PFMS), was prepared. The preparation technology was optimized and the optimized PFMS product was used to treat actual textile wastewater. The performance of PFMS was evaluated and compared with those of conventional coagulants. X-ray diffraction and infrared spectrometry show that PFMS is a macromolecular composite polymer of ferric and magnesium based on -OH bonds. The coagulation performance of PFMS is better than those of PFS, PAC, and PFC. The coagulation mechanism of PFMS in treating actual textile wastewater is primarily driven by charge neutralization at low dosages and co-precipitation netting at high dosages.
