4 Solids Removal/Filtration in Water Treatment Filtration Filtration Filtration OR Further Filtration for plant uses

5 Filtration Basics Nature of Solids Hard- Sand, Grit Settleable Deformable Fibrous Amount and size of solids % Particle size range What needs to be removed

6 Solids Separation with Vortex/Cyclone/Centrifugal Separator for Grit removal system

7 GRIT REMOVAL SYSTEMS Grit Vortex, Washers, and Classifiers Grit Vortex Grit Classifier Grit Washer Up to 52MGD (8200m3/h) Cast-in Concrete Up to 440GPM (100m3/h) Grit Removal Efficiency: > 80% grain size > 200 μm VOC Reduction > 50% Up to 90% DS up to 396GPM (90m3/h) Grit removal efficiency > 90% grain size > 200 μm VOC reduction > 50% Up to 90% DS

8 Centrifugal (Cyclone Type) Separators

9 How does it work

10 Efficiency % Centrifugal Separators

11 PWC (public works certified) Centrifugal Separators NSF certified Models for drinking water Applications Public Works Certified (PWC) centrifugal separator is a special design to meet the unique requirements of municipal water systems

12 Vortex/Cyclone/Centrifugal Separator What do I need to know? Efficiency of particle removal Solid handling Grit extraction pump Air lift grit extractor Grit Classifier or hopper Vortex VS Conical Hydrocyclone VS Centrifugal separators Mechanical vortex grit removal systems or induced vortex separators Headloss Abraison
