Flocculants for Clay and Dirt Solids Removal

The best flocculant depends on your application. For stormwater treatment and construction site runoff, bio-polymer chitosan-based flocculants like Biostar-CH are highly effective. They target fine clay and dirt particles too small for standard filters, are non-toxic and biodegradable, and break down quickly in the environment — making them ideal for sensitive sites and regulatory compliance.

A flocculant is a chemical or bio-polymer agent that causes fine suspended particles — such as clay, silt, and dirt — to clump together into larger masses called flocs. These flocs then settle or are filtered out of the water more easily. Bio-polymer flocculants like chitosan work by binding to charged sediment particles and aggregating them for efficient removal.

Yes. Bio-polymer flocculants made from natural chitosan material are non-toxic, non-hazardous, and fully biodegradable. They break down quickly in the environment without leaving harmful residues, making them a responsible choice for construction sites near waterways, stormwater management areas, and environmentally sensitive locations.

Flocculants are effective at removing fine clay particles, dirt, silt, and other suspended solids from water. They specifically target the smallest particles that are too fine to be captured through standard filtration processes. Common applications include stormwater treatment, water clarification, lime softening, sludge thickening, and solids dewatering on construction sites and waterways.

Bio-polymer flocculant solutions are typically classified as temporary, lasting up to 12 months. This makes them well-suited for project-based applications such as active construction sites or temporary stormwater treatment systems. Once applied, they act quickly to aggregate fine sediment particles and degrade naturally after fulfilling their treatment function.

Absolutely. Flocculants are widely used on construction sites to treat stormwater runoff containing clay and fine sediment particles. They are applied at channels, waterways, and stormwater inlets to clarify water before discharge. Bio-polymer options like Biostar-CH are particularly effective for meeting stormwater permit requirements due to their non-toxic and biodegradable formulation.
