    • DEPURFER range: Coagulants made from simple iron salts.
    • DEPURAL range : Coagulants made from combinations of pre-polymerised or simple aluminium salts.
    • DEPURGREEN range: Environmentally-friendly organic coagulants as a high-performance, more sustainable alternative to traditional metal salts.
    • Specific formulations: Coagulants based on combinations of iron and aluminium salts and organic coagulants formulated for specific problems.
  • BD POLIFLOC: Range of solid and liquid flocculants. Our formulations include anionic , cationic, combined and nonionic high-molecular-weight polyacrylamides. We also offer polyacrylamide-free flocculants that comply with the requirements ofUNE:EN 1408:1998for products used in the treatment of water for human consumption.
  • PH MINUS – PH PLUS: pH increasers and decreasers with formulations in different concentrations and delivery formats.
  • DEPURCAL:Calcium hydroxide in bags, used to increase the pH of treated water and improve sludge dewatering.
