The US Bureau of Reclamation, I. Moch coagulation and flocculation with PAC, alum, ferric chloride ferrous sulfate orpolyelectrolyte; disinfection by chlorine, monocloramine, ozone and UV; lime/sodasoftening; electrical, including energy recovery, and chemical consumptions and variousintake and outfall infrastructures. A number of water compositions are suggested forthose who do not have actual ion concentrations. Labor and supervision, membranereplacements, amortization rates and tanks, piping and instrumentation are also included,thus, permitting calculation of plant capital requirements and operating and maintenancecosts for all commonly employed aqueous separation processes.A number of these CD ROMs have been released and reports back are that the programgives reasonable, consistent estimations for plants costs. Specific project numbers, basedon direct site conditions, do require competitive tenders by the buyer.This paper compares, on a common basis, various seawater cases involvingchanges in such items as plant capacity, feed water salinity, system recovery, feed watersource and temperature as an assist in the selection of the least costly project option inproviding potable water to deprived areas. Includes 4 references, tables, figures.
