EVALUATION OF CAPITAL-COST DATA .9. LIQUID WASTE-DISPOSAL WITH EMPHASIS ON CHEMICAL TREATMENT

Capital cost correlations are given for chemical feed systems, chlorin ation, ozone disinfection, ultraviolet light disinfection, ion exchang e, flocculation, and carbon adsorption. Most of the correlations are a ccurate to +/- 30%, expressed in Canadian dollars and adjusted to a Ma rshall and Swift value of 1000. Details as to what components are incl uded 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 int o perspective, several hundred sources of cost data were analyzed. The major correlations are compared, on a consistent basis, with current data.
