This powerpoint presentation begins by providing a brief overview of a 1.5 mgd submerged ultrafiltration (UF) membrane
facility in Puerto Rico. Its
source water is Lagos Guajataca, PREPA impoundment.
The finished water often exceeds secondary drinking water
standard (SDWS) for manganese (Mn) of 0.05 milligrams
per liter (mg/L). The objective was to:
characterize raw water;
evaluate alternative treatment processes for Mn;
select recommended treatment process; and,
prepare preliminary capital costs.
Raw and finished water characterization is presented, along with
current treatment processes,
manganese reduction / removal treatment
alternatives, recommended treatment method, and
capital cost estimate. Other recommendations include the following:
institute coagulant addition (PACl or ACH)
with rapid mix device; add self-cleaning strainer for raw water; and,
determine adequacy of membrane integrity
test apparatus. Includes tables.
