Dye & Industrial Colour Removal from Wastewater

The presence of colour in discharge water is often caused by dissolved organics and tannins which are created during the tea manufacturing process.

Colour contamination in wastewater also has serious environmental consequences which can directly impact your business.

• Natural dissolved organics: humic and fulvic acids, natural tannins along with synthetic chemical dyes.

• Manufacturing processes: not only can colour affect the aesthetic value of water, if coloured wastewater is discharged to nature, photosynthesis activity is limited which is proven to cause detrimental effects on aquatic ecosystems, such as population decreases in aquatic species.
• Bioaccumulation of chemicals in the food chain

Businesses that use water in their manufacturing processes have a responsibility to ensure that any water discharged into the environment or local sewer has been treated and meets discharge regulations or directives. To do this, colour concentration levels must be monitored.

Colour in water is measured in Hazen Units (HU) or Platinum Cobalt Units (PCU). There are standards which provide guidance on the safe level of colour in discharged waters.

By implementing an advanced onsite treatment process to remove hard-to-treat dyes and colour causing chemicals, you will avoid regulatory fines and reputational damage.
