CeraCap - Low Density Anthracite
CeraCap is low density anthracite that is screened to a precise effective size (“ES”) and a low uniformity coefficient (“UC”). The low density of the material ensures that it will stay properly stratified creating a high solids retention zone at the top of a Ceraflow filter. The presence of CeraCap increases total solids capacity of the filter without compromising the effluent quality.
CeraCap is ideal in conjunction with Ceraflow for pressure filter applications such as:
- Where coagulation or filtration aids are employed.
- Highly variable feed water quality or where intermittent spikes of high solids may occur.
- High levels of ferric iron or oxidized manganese.
- Parameter: CeraCap
- Effective Size: 0.5 mm — 0.6 mm (25-35 Mesh)
- Uniformity Coefficient: < 1.4 (1.25 Typical)
- Density: 42 lbs/ft3 (0.67 g/cm3)
- Compatible Ceraflow Media: Ceraflow-50 & Ceraflow-70
- Recommended Backwash Rate: See Expansion Curves
- Acid Solubility: <5%
CeraCap is low density anthracite specifically screened for compatibility with Ceraflow filter media. It is recommended for applications where there is there is an influent solids loading. > 2.0 ntu or 1.0 mg/1 TSS .
CeraCap is pure anthracite and is considered inert and non-reactive and is compatible with all types of oxidants.
CeraCap with Ceraflow has a recommended operational flow rate of 8—10 gpm/ft2 (18.3—24 m/h). Design flow rates will vary depending on solids loading and desired filter run times.
Standard packaging is 1.3 ft3 (0.03 M3) 50 lb bags (22.68 kg).
