Specialty Chemicals

SPECIALITY CHEMICALS - KREYWIN offers complete range of specialty chemicals & customized chemical treatment programmes for optimum plant performances.

A) Polyelectrolytes – Coagulants, Flocculants (Cationic, Anionic, Non-Ionic), Polyamine & Polydadmac

We offer range of polymers for solid-liquid separation to varied industries. Solid-liqu id separation is encountered in major industries such as chemicals, fertilisers, steel, paper and mineral processing. Our polymers are used in varying range of molecular weight and ionicity to suit specific application. polymers can be profitably used for

  • Treatment of industrial and potable water
  • Recycling of waste water
  • Recovery of valuable raw materials
  • Sludge thickening and dewatering for disposal, which meets the pollution control standards
  • We offer synthetic cationic polymers which are polyacrylamides with medium to high molecular weight and easily soluble in water. These are available in powder form in following ionic types

  • Cationic
  • Anionic
  • Non ionic
  • We also offer anionic emulsions for specific applications in water, waste water and process applications.

    Polymers are specially designed to improve the efficiency of solid-liquid separation in processes like:

  • Clarification
  • Sedimentation
  • Filtration
  • Sludge thickening
  • Dewatering
  • Centrifugation
  • C) Cooling Water treatment chemicals
