Abstract
The conventional treatment methods of tannery spent float is found to be not sufficient to meet the required international standers levels of liquid discharges on the other hand the establishment of the treatment unit for the physical, biological and chemical treatment of the spent float is found to be extremely high-cost process. During the life time of the tannery by using the recycling of the spent float method, there would be a great saving in the water and the chemicals as well as environment protection. The comparison of the capital cost estimates of two tanneries with the same capacity, one with the conventional treatment method (large treatment unit should be established) and the other used the recycling of the spent float process, show the advantages of using the recycling process over the conventional treatment process.
Highlights
The cost benefit analysis may be used to compare completed or potential courses of actions, or to estimate the value against the cost of a project
Types of Capital Cost Estimates An estimate of the capital investment for a process may vary from a predesign estimate based on few information to a detailed estimate prepared from complete drawings and specifications
The major equipment is the same for both, only the establishment of treatment unit is necessary in the conventional method, there is additional equipment had been required for the recycling process
