Sizing of buffer tank

Design form:

Why a buffer basin changes the life of your WWTP or process

A well-sized buffer basin is the difference between an installation that is subject to its flows… and an installation that controls them.

The role of the buffer basin is simple:

  • smooth out flow variations (peak hours, CIP washes, rainfall, tank emptying, etc.)

  • homogenize the pollutant load before the sensitive steps (coagulation/flocculation, biological treatment, settling)

  • Protect downstream equipment from hydraulic jolts and concentration shocks

The 1H2O3 buffer tanks are designed as real process components, not as simple “storage holes”:

  • Compact square tanks → maximized usable volume for minimal footprint

  • Modular structure (BOX) → easy integration with other modular technologies 1h2o3

  • Choice of installation → buried, semi-underground or above ground according to your site constraints

  • Resistant and 100% recyclable materials (PP, PE, PVDF, ACS)

  • 50 mm insulating > honeycomb shell → better thermal stability and mechanical strength

  • Numerous process options→ integrated pumps, sloping bottom, perforated tank for hot effluents, ventilation, ventilated overflow, pH preparation, etc.

The result: a much more stable operation of the downstream stages, less clogging, less nuisance and a more serene operation.

How to size a buffer basin?

The volume of a buffer basin is not chosen “by feeling”. It depends in particular on:

  • Average flow and daily profile (peak/off-peak hours)

  • Peak flow rates (washes, batch discharges, weather events, etc.) it depends on the inputs of the project)

  • Desired buffering time (time during which you want to smooth the flow)

  • Type of effluent (urban, agri-food, chemical, wine, aquaculture, etc.)

  • Temperature (presence of very hot or temperature-sensitive effluents)

  • Downstream constraints (capacity of biological reactors, decanters, networks, etc.)

  • Possible need to correct pH prior to the main process

The form below allows you to enter this data. The calculation algorithm then proposes a volume of buffer basin consistent with your constraints, and the appropriate 1H2O3 model(s).
