INNOVATION IN WATER AND WASTEWATER TREATMENT PLANTS
Italy’s largest power company, Enel had five coal-fired plants that discharged
flue gas desulfurization wastewater into the sea. To comply with environmental
regulations, Enel chose a two-part solution: feed pre-scrubbers with fresh and
recirculated waters and install zero liquid discharge (ZLD) plants. The ZLD plant
is a fully integrated, automated system that produces industrial-grade soft
water and high-purity distillate for use in the power plant.
As the EPC contractor, Aquatech supplied, installed, and commissioned the
ZLD plants. AutoPLAN T enabled the project team to design one plant and port
the design to the other plants, which helped compress the schedule as well
as facilitate reviews with process engineers. Bills of materials were easily
consolidated for purchasing power and then split for delivery to separate sites.
Visual model reviews overcame any language barriers.
City of Phoenix 24th Street Water Treatment Plant
Phoenix, Arizona, United States
To control the formation of disinfection by-products in a potable water
distribution system, the city of Phoenix, Ariz., implemented an innovative
3D design for a $65 million, 120 mgd granular activated carbon post-filter
contactor facility. Efficient interaction between the city and contractor using
3D models visualized the intricate design, accommodated plant operator needs,
and minimized and resolved conflicts between various elements within the
contactor pipe gallery.
Weekly team meetings—using Project Wise to share files and submit
drawings—facilitated coordination among the prime consultant and two major
subconsultants. The enhanced design process using MicroStation, PlantSpace, and
STAAD.Pro allowed the city to improve water quality for customers within budget
while making the project up to 25 percent more profitable for the contractor.
