Silt Netting
Silt Net
Silt Net is a 100% biodegradable rolled product, suspended in lagoons or rolled out in ditches to improve settlement, reduce erosion and polish water.
Silt Net is supplied in two forms:
- Untreated Silt Net – a natural filter medium that slows flows and traps suspended solids.
- Treated Silt Net – pre-impregnated with Clearflow Gel Flocculant™ to bind fine particles, enhance settlement and improve water clarity.
It is commonly used for:
- Suspended in settlement lagoons and ponds; as a curtain to break laminar flow, extend pathways and boost treatment performance.
- Rolled out and staked in ditches; to reduce erosion and capture suspended sub-soils.
- Creating longer flow paths within treatment ponds for longer retention.
