Cost function for reverse osmosis

Cost Functions

The original cost function (A1) is as follows:

Función de costo para ósmosis inversa (1)

The cost function for reverse osmosis is based on the flow of the plant, and the nitrogen and sediment concentrations present at the entrance of the plant. This article presents how to obtain the final equation.

Función de costo para ósmosis inversa (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 Cost Functions Wiki — General.

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

Función de costo para ósmosis inversa (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.
