Cost function for bed filtration

Cost Functions

The original cost function (A1) for bed filtration is the following:

Función de costos para filtración en lecho (1)

This function has as variable (x) the filtration flow in millions of gallons per day (mgd). To convert it to Flow (in L / s) the following relationship was used:

Función de costos para filtración en lecho (2)

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 article Cost functions — General.

Based on the above, the following is the function obtained:

Función de costos para filtración en lecho (3)

  1. Preliminary Cost Estimation Models for Construction, Operation, and Maintenance of Water Treatment Plants Jwala R. Sharma, Ph.D., M.ASCE; Mohammad Najafi, Ph.D., P.E., F.ASCE; and Syed R. Qasim, Ph.D., P.E., M.ASCE 2013

    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.
