Cost function for on-site generated chlorine dosing

Cost Functions

The original cost function (A1) for dosing chlorine generated on site is as follows:

Función de costo para dosificación de cloro generado in situ (1)

This function has as variable (x), which is the chlorine dosing capacity in lb / d (Pounds per day). The following relationship was used to express the flow function capacity as (L / s):

Función de costo para dosificación de cloro generado in situ (2)

Where Q is the flow rate and D is the applied dose. For Chlorine, a usual dose of 1.2 mg / L was taken. With this, the following replacement of the variables of the equation is proposed

Función de costo para dosificación de cloro generado in situ (3)

Additional modifications to this function correspond to the correction of costs per year, with the CCI ENR index of 9547 of the year 2013, to obtain A3. Then part B2 related to the elasticity index is added. This is done in the same way as explained in the Cost Functions Wiki — General.

According to the above, the function obtained is the following:

Función de costo para dosificación de cloro generado in situ (4)

    Reliable cost estimation of construction, operation, and maintenance (O&M) of water treatment plants is essential for project planning and design. The authors have developed construction and O&M cost models for different unit operations and processes involved in water treatment plants. This paper presents the use of a single cost index to further update construction and O&M costs.
