Clearflow Gel Flocculant Reactor
Clearflow GFR Systems
Built on proven Clearflow technology, the GFR range offers a high-performance, low-maintenance solution for treating silty and contaminated water on active sites.

The highly adaptable GFR units deliver powerful, portable and reliable water treatment without the need for new infrastructure.
There is a system for every application:
- Silt-laden pond dewatering
- Construction site runoff
- Temporary discharge treatment
- Linear infrastructure projects
- Environmental remediation
- Effluent treatment
- Mine water treatment
Key Benefits
Rain Ready® mobile water treatment at its best
Engineered for performance
Proven in the field, GFR units optimum Total Suspended Solids treatment is 5,000 NTU, although they are effective up to 20,000 NTU.
Portable water treatment
Designed with moveability in mind, GFR systems can be moved around the site with ease to suit different treatment zones.
Self dosing, self limiting system
The unit is built for simultaneous treatment and pumping and requires minimal maintenance.
Cost-effective water treatment
The GFR range cuts treatment and disposal costs, the slabs last between 2 – 6 weeks depending on water flow and soil make up.
Sleek, well built design
GFR is made from a stainless steel construction for long-lasting performance across multiple sites. When you require more treatment, purchase replaceable cartridges containing Gel Flocculant slabs.
