About This Tool

Design water softeners with accuracy using this advanced softener design calculator. Get real-time resin volume, brine tank sizing, vessel diameter, height, shell thickness, and dish end type based on flow rate and velocity. IS/ASME standards applied.

Design Standards

Recommended Parameters

  • Velocity range: 12–15 m³/hr/m² typical
  • Bed height: 1–2.5 m recommended
  • Freeboard: 30–50% of bed height
  • Dish ends selected based on pressure rating
  • Gravel layer: 200–300 mm
  • Leg height: 300–450 mm
