Pink Wastewater Treatment Costs for a Granular Carbon System Operating at Flow Rates at or Below Design Capacity.

摘要

The Present Value-Unit Cost (PVUC) methodology was applied to a hypothetical pink water treatment plant utilizing granular carbon adsorption and no regeneration of the spent carbon. The study analyzed the cost implications for a system design of 100,000 gallons per day (GPD) operating at its rated capacity after reduced flow values of the wastewaters are collected and stored versus the daily operation of the plant regardless of the influent flow rates. Examined and qualified in Present-VAlue dollars was the effect of dedicated versus part-time labor for operation of the carbon plant. The differences were then translated into potential annual savings and shown as a function of the daily input flows to the system. (Author)
