The Fastest Way to Design Sewage Treatment Plants

Why STP Design Calculations Are Difficult

Designing an STP requires precise calculations of:

  • Tank capacities (aeration, equalization, sludge)
  • Hydraulic retention time
  • Compliance with CPCB, KSPCB, or TNPCB standards

Manual calculations lead to:

  • Errors in complex formulas
  • Time wasted working with Excel spreadsheets
  • Exposure risks due to non-compliance with pollution boards

Our STP Design Calculator gets the job done—accurate designs in 3 simple steps.

How to Utilize the STP Design Calculator

Step 1: Enter Basic Project Details

  • Flow Rate (KLD): Residential (5-100 KLD), Commercial (50-500 KLD), Industrial (100-5000 KLD).
  • Technology: Choose ASP, MBBR, SBR, or MBR.
  • Location: Automatically formats for state PCB regulations (e.g., TNPCB vs. KSPCB).

100 KLD | MBBR Technology | Application Type

Step 2: Get Instant STP Design Report

The tool calculates:

  • Tank size (Length × Width × Depth)
  • Sludge & aeration capacities

- Aeration Tank: 50m³ (10m × 5m × 1m)

- Sludge Tank: 15m³ (3m × 3m × 1.67m)
