Evaluation of capital cost data: Part 9: Liquid waste disposal with emphasis on chemical treatment

Capital cost correlations are given for chemical feed systems, chlorination, ozone disinfection, ultraviolet light disinfection, ion exchange, flocculation, and carbon adsorption. Most of the correlations are accurate to ± 30%, expressed in Canadian dollars and adjusted to a Marshall and Swift value of 1000. Details as to what components are included in the cost are given. Data are given for the labour and material costs to create a working process module. To put the current data into perspective, several hundred sources of cost data were analyzed. The major correlations are compared, on a consistent basis, with current data.
