Clearflow Gel Flocculant Blocks
Award-winning, self-dosing gel technology engineered to passively target and bind suspended solids, heavy metals, and nutrients.
Hardware & deployment systems
A new family of compact, versatile, high-performance clarifiers. High-capacity, mobile water treatment engineered to deliver robust solids removal at the point of need - scaled by capacity, not complexity.
System overview
The ARC family pairs Clearflow's patented Gel Flocculant technology with an optimized clarification chamber to drive rapid settling and consistent self-dosing under variable flows. Whether treating construction runoff, industrial process water, or mine site discharge, it produces clear, reuse-ready effluent and a concentrated sludge stream that simplifies on-site handling.

Core technologies
01
Award-winning, self-dosing gel technology engineered to passively target and bind suspended solids, heavy metals, and nutrients.
02
Engineered flow-through vessels designed for the passive, self-dosing release of the gel chemistry.
03
High-density lamella clarification plates, precisely angled to maximize surface area and accelerate settling speeds 3 to 5 times faster than traditional methods.
04
Specially designed dual sludge hoppers that efficiently consolidate captured solids for rapid, hassle-free pump-out and disposal.
