Circular Clarifier
The backbone of many water and wastewater treatment plants
Traditional yet highly effective and using gravity-based sedimentation, these large-diameter units promote even sludge settling while minimizing turbulence. Their robust design allows for efficient solids removal in high-flow environments, making them indispensable for large-scale treatment facilities.
