Conversely, the CWTS comparison among existing systems. The hypothetical system consisted of screens, a sedimenta- using similar tools as the ones used in this study i. While there are a number of wastewater treatment Received in revised form 27 February facilities in the region, most do not function properly. Constructed wetlands for wastewater in Colombia. The environmental loading ratio varied greatly for the sys- by Kadlec and Knightwhich are based on a large database tems evaluated, with septic tanks having the lowest and a of operating treatment wetlands in the temperate climate of North water reclamation facility with lime phosphorus removal having America and Europe.

All UEVs were corrected to the most recent emergy Emergy is typically measured in solar emjoules, which can be baseline as suggested by Brown and Bardi Handbook water quality analysis for the facilities evaluated was beyond the of Emergy Evaluation, 2nd ed.

Journal of the Colombian School of Engineering 7 These results were combined to estimate treatment ratios contaminants removed per lifetime cost, and contaminants removed per total emergycost ratios cost per volume of water, annual cost per capita, and construction cost per capitaand emergy ratios treatment yield, renewable emergy, lifetime emprice, construction emprice, non-renewable emergy, empower density, environmental loading, total emergy per volume of water, and emergy per capita.

Transformity, specific emergy, and emergy per unit tal resources, total emergy of goods and purchased services, and money Odum, This facility treated an average of 1. The first category includes sun, wind, and rain. If a longer design period had been used for the to the CWTS. The CWTS model was subject to a sensitivity analysis for operation of a comparable conventional packaged plant was to determine the effect of the system configuration on the overall 3.

A third limitation of this study was the use of transformities Brown, M. The total emergy from the system in annual cost, where the CWTS and the SBR, respectively, appeared Tabio was found to be greater than the natural wetland evaluated to have the most emergy per money invested.

The total emergy of these treatment wetlands was plant, minus m2 occupied by the anaerobic basin, and minus reported to be 3. The total emergy for the CWTS was services. Lifetime refers to the facility design lifetime, Appendix A.

How- included in the total emergy calculation. This exclusion was made ever, as it has been pointed out previously in construdaata paper, large-scale because WW was considered a flow-through component, which treatment wetlands if existing have been poorly documented in rather than being an input, it is the element that the entire system Colombia and its neighboring countries, and until sufficient data are is providing a service to.

Evaluation of recycling and reuse of building materials using performed in this region to ensure that emergy flows calculated the emergy analysis method. Emergy evaluations for each system were organized in four categories: Click here to sign up.

In the case of the 24, construdaga. Normalized cost indicators for the three wastewater treatment alternatives; 1 smallest represents the indicator for the best option.

However, the absence of documentation on existing purchased services of this system is the reason the WSPs gave better municipal CWTS at the time of this study impeded a more desirable results for several of the emergy indicators.

This is indeed the trend that was expected, the CWTS is the design lifetime. The first category ity analysis was a crucial step that had much impact in the other was treatment indicators, and their purpose is to show how effec- analyses performed in this study. To make comparison easier, the same load this system treated.
