Description:
Powdered activated carbon has been the subject of several developmental efforts directed towards producing improved methods for treating municipal wastewaters. Granular activated carbon has proven itself as an effective means of reducing dissolved organic contaminant levels, but is plagued with specific operational problems which can be avoided with powdered carbon. The work reported herein was aimed at putting powdered activated carbon (PAC) treatment in proper perspective relative to competing technology. All work with PAC and PAC regeneration was reviewed and representative process approaches selected for comparison with granular activated carbon. While no one PAC approach is clearly superior from a performance standpoint, biophysical processes are attractive because they can be incorporated into existing biological plants. Comparison of capital and operating costs were made for plants with throughput rates of 1, 5, 10, 25, and 50 MGD. Cost relations were generated in curvilinear relations to allow interpolation.
