TREATMENT COSTS


Advanced Treatment (filtration after coagulation + carbon adsorption)

This costs computation concerns the following units of treatment:

  • Secondary treatment
  • coagulant addition
  • in-line mixer
  • filtration
  •  Granular activated carbon contactor (GAC)
  • disinfection (chlorination)

The treatment costs, including  capital, operation and maintenance costs, have been obtained assuming a daily pro-capita discharge of 300 l/EI-d. If you want to meet the treatment cost for different values of daily pro-capita discharge, the following link must be activated.

AUTOMATIC COMPUTATION COSTS OF TREATMENT

 

Treatment cost for daily pro-capita discharge of 300 l/EI-d

The unit treatment costs, expressed in £/m3, have been obtained with the following equations:

 x < 30.000 EI:

y = 2191 – 0.0269 x

 x >=30.000 EI:

y = 1410 – 0.0009 x

y = unit cost in £/m3

x = equivalent inhabitants (EI)

The following Table shows the unit costs for the principal capacity plant.
