Development of 3-D Surface Cost Response Maps for Predicting Rapid Costs of Biological Wastewater Treatment Using Moving Bed Biofilm Reactors
摘要
Moving Bed Biofilm Reactor (MBBR) is employed for economical municipal and industrial effluent treatment. However selection of the treatment technology should have a techno-commercial rationale so that the effective cost for sustainable implementation encapsulates economic and fiscal aspects. This paper presents the study made to work out the profile of variation of cost of WWTP with MBBR for different input BOD at varied flow rates and development of 3-D surface cost response maps based on generated data sets to provide instant information on cost of WWTP with MBBR. These 3-D maps are extracted from software by use of the data obtained as output from a model developed for system design, determination of bill of quantities and cost. No literature cost data has been used in this context. These 3-D maps developed for WWTPs with MBBR technology may be used to forecast costs for construction, operation and maintenance for twenty five years. This will provide stakeholders reliable and rapid cost information for WWTP with MBBR technology and enable them for comparison with other alternatives for a prudent selection of technology, particularly for decision makers.
