Cost function for sludge band filters

Cost Functions

The original cost function (A1) for the band filter is as follows:

Función de costo para filtro de bandas (1)

This has as variable (x) the sludge pumping rate in gallons per minute. Applying the conversion factors from gallons per minute to liters per second, applying a factor of 5% which represents the sludge production that occurs in a plant and applying the elasticity factor, the function obtained is as follows:

Función de costo para filtro de bandas (2)

  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.
