Pretreatment & Clarification
Stronger Pretreatment. Cleaner Filters. Longer System Life.
Effective pretreatment is critical for reliable downstream filtration, membrane performance, and regulatory compliance. Roberts Filter Group provides proven clarification technologies — from high-rate upflow clarifiers to plate settlers — that handle variable source waters and protect the entire treatment train.
Our Pretreatment & Clarification Solutions
ContaClarifier®
Roberts clarifiers are engineered to remove suspended solids efficiently, even under variable water quality conditions. Available in both conventional and compact designs, they reduce turbidity, lighten the load on filters, and improve overall system stability.
Plate Settlers
Inclined plate settlers allow high-rate clarification in a compact footprint. These systems maximize settling area while minimizing tank size, making them an ideal solution for plants with space constraints or expansion needs.
Spyder® Sludge Collection
Our zoned sludge-withdrawal system ensures uniform solids removal across the sedimentation basin floor. The Spyder® reduces maintenance, prevents sludge buildup, and keeps sedimentation performance consistent over time.
Microwedge® Sludge Drying System
The Microwedge® is a passive, modular system that simplifies sludge dewatering and drying. Built from durable interlocking blocks with no moving parts, it provides a low-maintenance way to handle sedimentation sludge withdrawal flows. Its modular design allows plants to expand capacity as needed, while offering a reliable and cost-effective solution for reducing sludge volume without the complexity of mechanical equipment.
