How Chitosan Works For Water Purification

As a highly efficient natural, bio-active fibrous polymer, chitosan has great potential, with dozens of applications, including water purification and wastewater treatment.

chitosan and its potential for water treatment

The natural chitosan biopolymer has distinct advantages, including outstanding antimicrobial action and pollutant-binding capacity. It is biocompatible, non-toxic and biodegradable, versatile in form and has a relatively low cost of production. These attributes make chitosan an eco-friendly material for water clarification and purification, biofiltration, pollutant elimination and treating water and wastewater.

Chitosan and its derivatives, such as chitosan powder, is an excellent biosorbent with outstanding pollutant-binding capacities. It can effectively bind to a wide range of organic and inorganic pollutants, such as heavy metal ions, suspended solids, fat and oil impurities, bacteria, ammonia, and textile wastewater dyes. Thanks to its flocculant activity, it improves sedimentation and filterability of small particles by causing them to aggregate, forming a floc.

As chitosan manufacturers with over 20 years of experience and a state-of-the-art chitosan factory, we can provide our clients with pure, high-quality chitosan, in bulk, or develop other formats with multiple applications across industries, including water treatment and purification.


Chitosan as a water purification agent:

  • reduces the formation of chloramines, reducing chlorine burning effects
  • encapsulates body oils and cosmetics
  • reduces odours
  • provided filtration for cartridge, sand and D.E. filters
  • can be easily removed via filtration or sedimentation with no toxic chemical residue
  • clears hazy sea water for underwater photography

As a natural, fibrous biopolymer, chitosan is an excellent material for environmental purposes. It can be formulated into soluble or insoluble gels, liquids, membranes, fibres and beads. As an eco-friendly material, it has the potential of replacing metallic salts and synthetic polyelectrolytes.
