Water decolorizers are chemicals that are specifically designed to remove colour and other contaminants from wastewater, and they play an important role in the field of water treatment. Here is some key information about water quality decolourisers:

  1. definition and function:
  2. Water decolorants remove unwanted dye groups from wastewater, and they usually combine multiple functions such as decolourisation, flocculation, and COD degradation.
  3. Decolorizers make water clear by adsorbing pigment particles, neutralizing charges, and flocculating suspended substances.
  4. Application scope:
  5. It is mainly used for the decolourization of high-colour wastewater of dyestuff factories, and is suitable for the wastewater treatment of reactive, acidic and disperse dyestuffs.
  6. It can also be used in textile and printing and dyeing wastewater treatment, pigment, ink, paper and other industrial wastewater treatment.
  7. It can also be used as reinforcing agent and sizing agent for papermaking.
  8. Quality standard:
  9. Appearance: light colour, viscous liquid.
  10. Viscosity 20°C: 3-5s.
  11. pH value (30% aqueous solution): 3-5.
  12. Solid content ≥50%.
  13. Method of use and dosage:
  14. Dilute the product with 10-40 times of water, then add it into water directly, stir for several minutes and then carry out sedimentation or air flotation to get the clear liquid after decolourisation.
  15. The pH value of wastewater should be adjusted to 4-12 first.
  16. When the colour and COD of the wastewater are high, it is advisable to use the decolourant together with organic coagulant aid (PAM) to treat it.
  17. Storage conditions:
  18. The product is non-flammable and explosive, it should be stored at room temperature, do not expose it to the hot sun.
  19. Laboratory small test process:
  20. Take the appropriate amount of wastewater with a beaker (500ml or so), adjust the pH value; add drops of chemicals: first add a certain amount of decolorant (0.5 ‰ -3 ‰), stirring, and then add 1 ‰ of PAM three, five drops, stirring, standing; observe the supernatant chromaticity whether to meet the requirements, such as not to meet, adjust the amount of chemicals dosage, repeat the operation.
  21. Market situation:
  22. With the improvement of environmental protection consciousness and the strengthening of pollution prevention and control, decolouring flocculant will play a more important role in the field of water treatment.
