A & S Automations

1. Design Inputs

Required Product Flow (m³/hr)

Raw Water Hardness (as CaCO₃, mg/L)

Operating Hours per Day (hr)

Total Dynamic Head for Pump (m)

Pump Efficiency (%)

2. MGF (Multigrade / Sand Filter) Design Parameters

Media quantity is calculated from design filtration rate and bed depth based on the required product flow.

Design Filtration Rate (m³/hr·m²)

Sand Bed Depth (m)

Sand Bulk Density (kg/m³)

3. Softener Design Parameters

Resin volume is calculated from service velocity and bed depth at the same product flow. OBR and salt per regeneration are based on resin capacity and hardness.

Service Velocity (m³/hr·m²)

Resin Bed Depth (m)

Resin Bulk Density (kg/m³)

Resin Working Capacity (kg CaCO₃ per m³ resin)

Salt Dose per Regeneration (kg NaCl per m³ resin)
