Nature's Most Effective
Water Purifier
Chitosan is one of nature's most effective water treatment agents. As the only bio-polymer carrying a natural positive charge, it interacts with contaminants at a molecular level — removing suspended particles, heavy metals, organic pollutants, and harmful microorganisms without introducing toxic byproducts.
Key Purification
Mechanisms
Chitosan works through four distinct scientific mechanisms, making it effective against a broad range of water contaminants — from suspended solids to dissolved heavy metals.
Coagulation & Flocculation
Chitosan's positive charge neutralises suspended particles, causing them to clump into larger flocs that settle or filter out — significantly reducing water turbidity.
Heavy Metal Adsorption
Hydroxyl and amino groups act as chelating agents, binding directly to toxic metal ions — lead, copper, mercury, and arsenic — safely extracting them from wastewater.
Organic Contaminant Removal
Effectively encapsulates and removes oils, microplastics, pharmaceuticals, and synthetic dyes from industrial and municipal water streams.
Antimicrobial Action
Naturally inhibits the growth of certain bacteria, algae, and fungi — contributing to biological disinfection without the need for harsh chemicals.
Why Choose Chitosan
for Water Treatment
Eco-Friendly & Sustainable
Upcycled from crustacean shells — shrimp and crab — a renewable natural byproduct that would otherwise go to waste.
No Toxic Sludge
Unlike alum and metal-based coagulants, Chitosan produces biodegradable sludge that is safe to handle and can be repurposed as fertiliser.
Regulatory Approved
Approved by the U.S. EPA and international regulatory bodies for use in drinking water purification and stormwater treatment.
Versatile Application
Effective across ETP, STP, industrial wastewater, and municipal water treatment plants of all scales.
Research-Backed
Validated through decades of R&D at Sri Balaji Biotech and supported by global scientific collaboration since 2014.
