What is Chitosan Enhanced Sand Filtration?
For 15 years, our Chitosan Enhanced Sand Filtration (CESF) units have been the most cost-effective, and environmentally friendly solution to your turbid water concerns. Our self-contained units can be installed anywhere, even on construction sites with limited space. They filter turbid water from soil disturbance, contamination from previous developments, and treatment of PH from concrete handling on-site.
Our filtration units take dirty water from construction and industrial sites and filters out these contaminants quickly and more effectively than other filtration mediums.
Choosing CESF units on your site is a smart choice:
- Lower project costs
- Improve site conditions for contractors
- Increase wastewater tank capacity
- Work for all soil types
- Install easily in areas with limited space
- Environmentally friendly
- Comply with current EPA and WSDOE BMP regulations
