high-quality raw water at a premium in South Florida, the City of
Hollywood was forced to tap into the Floridan Aquifer to supplement its
Biscayne Aquifer supply. The Floridan water is dependable and abundant but
of significantly lower quality than that from the Biscayne. To address
this issue, Hollywood contracted M&E to conduct a treatability study
and to provide design and construction services to upgrade the city's
water treatment plant.
Rather than combining raw water supplies prior to treatment, M&E integrated three distinct treatment processes into a cohesive system. The existing lime-softening system was rehabilitated, maximizing use of existing equipment. M&E engineers designed a nanofiltration process to treat water from the Biscayne Aquifer, ensuring SDWA quality at the lowest possible cost. Then, to treat the Floridan Aquifer's brackish water, M&E designed a reverse osmosis system. The upgraded plant blends 18-mgd of lime-softened water, 14-mgd of membrane-softened water and 4-mgd of reverse osmosis water before transfer to a distribution storage system.
Other project features included construction of four new Floridan Aquifer wells; construction of mains to serve the membrane treatment facility; and consolidation of all system controls in the membrane treatment building. M&E's innovative solution provides optimum flexibility, maximum cost-efficiency and full regulatory compliance as well as providing great tasting water to Hollywood's customers.
