Chitosan Flocculants 

Chitosan is a natural biopolymer derived from chitin, recycled from the shells of crustaceans like shrimp, crabs, and lobsters.

Natural Water Treatment Chemistry

Chitosan has been trusted across North America in reducing turbidity and removing unwanted particulate contaminants in the most sensitive ecosystems and regulatory environments. Since Chitosan is acrylamide-free and 100% biodegradable through enzymatic activity, it ensures that there are no bioacculmulation concerns after treatment.

Treatment systems using chitosan are adaptable and highly versatile to achieve water quality goals on projects with varying site conditions, soil types, and seasons.Chitosan performs best in waters that have a ph of 6.5-9 and TSS up to 10,000 mg/L.

Additionally, Chitosan creates floc solids with a lower percentage of water entrained, which creates a stable and strong floc. A high-quality floc allows treatment systems to run more efficiently with benefits both upstream and downstream:

  • Fast settling times

  • Easy filtration and backwashing

  • Reduce hauling and disposal costs

  • Removes a variety of solids - including fine sediment, heavy metals, and PCBs

An Environmentally Safe Solution For Every Industry

Some of the most stringent and environmentally sensitive regulatory agencies prefer chitosan-based flocculants over synthetic alternatives for water treatment, based on toxicity testing that demonstrates no harm to aquatic organisms at recommended dosages.

Industrial Stormwater Treatment      

Capture dusts, particulate metals, and trace oils.  

Construction Site Water Treatment

Remove TSS and ntu from site stormwater, dewatering, and wheel wash.

Environmental Remediation

Capture particles like metals, asbestos, and PCBs.

Biosolids Management

Enhance dewatering for dredging and biosolids processing.

LiquiFloc 2% High View Here
LiquiFloc 3% Maximum View Here

Deployment methods:

  • Liquid dosing systems
  • Active and semi-passive treatment systems 

Available in 55 gallon drums or 275 gallon totes.


GelFloc is the dry powder version of Chitosan.  GelFloc is integrated into treatment systems as a sock.  The GelFloc Sock is a geotextile tube filled with GelFloc powder, designed to dose the chitosan by dissolving the powder into water as it flows over the sock.        

GelFloc socks will dose approximately 100ppm at 150gpm flow.  If a higher dose is required, or the system flow is higher, you can add additional socks in series.  Each sock will treat approximately 100,000 gallons of water, and is highly variable based on flow rate, water temp, and turbulence of the water flowing over the sock. 

 Deployment method:

  • Dry sock systems
  • Passive and semi-passive treatment systems

                Available in packs of 4 socks per 5 gallon pail.
