Exhibit_A.pdf

Exhibit "A" is a flow diagram for de-ionization systems associated with the City of Orlando's De-Ionization System Cylinder Maintenance contract opportunity, detailing water treatment processes for three specific locations: Iron Bridge Laboratory, Iron Bridge Operations, and Water Conserv II. The document provides a comprehensive step-by-step flow diagram illustrating the water purification process from tap water input through multiple filtration stages, including 1-micron and 0.2-micron filters, water softeners, carbon tanks, reverse osmosis (R.O.) membranes, storage tanks, pumps, de-ionization (D.I.) tanks, and ultraviolet (U.V.) light treatment, ultimately delivering purified water to laboratory environments.

Each location's water treatment system follows a similar but slightly varied multi-stage filtration process, with the Iron Bridge Laboratory having the most complex configuration involving three D.I. tanks and a polishing tank, the Iron Bridge Operations using two D.I. tanks, and Water Conserv II utilizing four D.I. tanks and additional Big Blue 15-1 filters. The flow diagrams demonstrate a sophisticated water purification methodology designed to remove impurities and ensure high-quality water for laboratory and operational use, highlighting the technical complexity of the city's water treatment infrastructure and the precision required in maintaining these de-ionization systems.
