ClariPro™ Clarifiers with Lamella Settlers
Efficient Clarification and Polishing for Water and Wastewater Treatment
ClariPro™ – Integrated Coagulation, Flocculation & Lamella Settling Unit
ClariPro™ is a modular clarification system that integrates chemical coagulation, mechanical flocculation, and counter-current lamella settling in a single compact structure. Designed for scalable deployment, ClariPro™ effectively treats a wide range of influent qualities with high solids loading and variable flow rates. The unit ensures enhanced particle removal, reduced sludge volume, and consistent effluent clarity, making it suitable for pre-treatment or polishing in water and wastewater treatment systems.
Process Description
The ClariPro™ process is designed to deliver rapid, high-efficiency solids separation by combining the following core stages:
1. Coagulation & Flocculation
Raw water enters the system and is first dosed with inorganic coagulants (e.g., alum, ferric chloride) in a coagulation basin, where initial microfloc formation begins.In the subsequent flocculation basin, polyacrylamide polymer and micro-sand are introduced. The polymer promotes bridging between microflocs, while the micro-sand serves as a ballast agent, enhancing the density and size of the flocs.
2. Lamella Plate Sedimentation
The flocculated water flows upward through an array of inclined lamella plates within the sedimentation tank. The dense, sand-weighted flocs rapidly settle onto the plates under gravity, separating efficiently from the water.
- Clarified water flows upward and is collected via weirs.
- Settled sludge, rich in suspended solids, is captured below.
3. Sand Recovery & Sludge Handling
The settled material is continuously pumped from the bottom of the clarifier to a hydrocyclone, which separates the micro-sand from the sludge.
- Recovered micro-sand is recycled back into the flocculation basin.
- Separated sludge is discharged for further dewatering or disposal.
Recirculation pumps transfer the settled material to the hydrocyclones to separate the micro-sand from the sludge and return it to the flocculation tank. The sludge is discharged to waste.
ClariPro™ – Typical Effluent Water Quality
| Parameter | Typical Effluent Range | Remarks |
| Turbidity | < 1 – 5 NTU | Often <1 NTU with optimized coagulation/flocculation |
| Total Suspended Solids (TSS) | < 10 – 20 mg/L | Can be <10 mg/L in stable operation |
| Biochemical Oxygen Demand (BOD) | 10 – 20% reduction | Some BOD removed with particulate-bound organics |
| Color | Up to 90% removal | Especially effective with ferric- or alum-based coagulants |
| Oil & Grease (O&G) | < 5 – 10 mg/L (with pre-treatment) | With upstream coalescer or surfactant conditioning |
| Phosphates | < 1 mg/L (with dosing) | With chemical precipitation as part of coagulation |
| Heavy Metals (particulate-bound) | Significant reduction | Depends on binding to suspended solids |
