Understanding Hydraulic Retention Time

HRT ies defined aas the voimme of the treatment tk divided by the flow rate of wateg through it. Ini adalah typicallty tretment or hour.

Kalkulating Hydraulic Retention Time

Te basic formula for HRT os:

Pertama; FLT: 0; 33; HRT = Volume of tank / Flow rate 1; FLT: 1 1f 3; 1f 3;;

Dimana:

  • Pertama; FLT: 0 = 33. Volume of tank = = FLT = 1 = 3 = 3 = 3 = D = m m mc / s
  • 1f 1f; FLT: 0 = 33; Flow rate 1; FLT: 1 1f 3; IS rea3d in meters per hour (m asht / h)

Pemeriksaan singkat, tangk with a volume of 100 m od a flow rate of 10 m results is un HRT of 10 hours.

Design Tips for Optimizing HRT

To improve treatment exicency, consider the followingg tips:

  • Asett tak berguna volume based on flow variations
  • Maintaian consistint flow rates to prevent short-ciriting
  • Use multiple tanks in n series to extend overall l retention time
