Explanation:
The City of Hollywood's Water Treatment Plant ("WTP") is a 60 million gallons per day (MGD) plant that not only provides high quality water to the residents of the City but also serves approximately 300 acres in the Town of Davie, 50 acres in the City of Dania Beach, and 100 acres in the Seminole Tribe of Florida reservation. WTP also provides wholesale water to Broward County's Water and Wastewater Services Districts 3A and 3B/C. In addition to retail and wholesale water services, the City has an emergency connection with the City of Dania Beach, which withdraws water from the City's system to maintain its system pressure.

WTP treats raw water from wellfields in the Biscayne and Floridan aquifers using three major treatment processes: lime softening ("LS"), membrane softening ("MS"), and reverse osmosis ("RO"). The water treated by each process is blended, disinfected, and pumped into the service area. The LS system was originally constructed in 1967 with treatment capacity expanded in phases. The major equipment/structures included in this system are lime silos, spiractors and filters.

The LS system treats water using a process known as fluidized bed crystallization which softens raw water in treatment units referred to as spiractors. After the water is softened in the spiractors, it is filtered by sand/anthracite steel vessel filters or by six traditional dual media (open) filters. The LS plant has provided reliable, high-quality water treatment for over 50 years....
