Book Description
This study provides cost estimates of construction and operation for granular activated carbon (GAC) adsorption of total organic carbon (TOC), and packed tower aeration (PTA) for air stripping of trihalomethanes (THMs). Costs were developed by employing software published by the United States Environmental Protection Agency (USEPA) through its Drinking Water Research Division (DWRD). Cost estimation for both methods required preliminary GAC and PTA designs based on data collected in the field and from earlier published sources, as well as modifications to the software used in this study. The resultant designs were focused on compliance with certain aspects of the Stage 2 Disinfection By-Product Rule (Stage 2 DBPR) for THM and haloacetic acid (HAA) concentrations in drinking water. Formation of disinfection by-products (DBPs) occurs when natural organic matter (NOM) found in water sources reacts with disinfectants, typically chlorine based, that are used for the inactivation of water-borne pathogens. DBPs included several groups of compounds that, when ingested, are known to be carcinogenic and have been linked to other serious health effects. Two principle locations were used in this study to represent a medium system (serving 10,000 to 99,999 people) and a large system (serving 100,000 or more people). Overall system cost estimates for GAC adsorption were between 24 and 41 cents per 1000 gallons with an apparent economy of scale existing for larger systems. Investigations into GAC reactivation suggest that off-site reactivation is more cost effective for small to medium systems while some type of on-site reactivation would be a more cost effective method for larger systems. Overall PTA system cost estimates were between 8 and 9.6 cents per 1000 gallons. Both methods are effective at THM control while GAC adsorption has the added ability to reduce non-volatile DBPs and naturally occurring material (NOM), as well as reducing taste and odor problems if present.
