Hydraulic Characteristics

Estimated bed expansion and pressure drop as a function of backwash flow rate and temperature are detailed in the official PDF. These estimations are valid at the start of the service run with clean water and a well-classified bed.

• Backwash Expansion: Temperature range 10 – 60°C (50 – 140°F) (See Figure 1 in PDF)
• Pressure Drop: Temperature range 10 – 60°C (50 – 140°F) (See Figure 2 in PDF)

Quality Assurance

AmberTec™ UP9700 is tested for total organic carbon (TOC) rinse down to meet stringent ultrapure water (UPW) performance requirements. A typical rinse curve for TOC is shown in Figure 3 of the PDF.
