* Source: For cost modeling, the following data for the Sequencing Batch Reactor (SBR) form of activated sludge process was gathered from the EPA’s 1999 Publication entitled “SBR Technology Fact Sheet”.
This publication also indicates that SBR manufacturers will typically provide a process guarantee to produce effluent of less than 10 mg/L BOD; 10 mg/L TSS, 5-8 mg/L Total Nitrogen, and 1-2 mg/L Total Phosphorus. As is clearly demonstrated in our Case Studies, AquaMats® Process is meeting or exceeding this level of treatment.
Cost comparisons are broken out based upon the following criteria for each sample size facility:
1. Capital Cost - This is defined as the complete installed cost exclusive of design engineering and permitting. These additional items will typically add 10 to 15% to the up-front system costs.
2. Annual Operating Cost - This is defined the items including labor, overhead, supplies, maintenance, operating administration, utilities, chemicals, safety & training, laboratory testing and solids handling. With respect to sludge hauling costs, a seperate Army Corp of Engineers estimate that says that 30-50% of the typical facility’s operating costs are associated with solids handling and disposal.
