PTSA is a colorless fluorescent dye that has been widely used for the determination of water volume for open and closed recirculating systems. The Pyxis Lab® VoluCheck PTSA System Volume Verification Kit comprises a laminated calculation and instruction sheet, Quantity 10 – 0.45 micron syringe filters and the following pre-weighted PTSA solutions: The Pyxis Lab® SP-350 or the SP-710 units should be used to measure PTSA residual.
The PTSA volume verification method is suitable in most recirculating water systems. Closed systemstreated with high levels of nitrite (>500 ppm) or containing high level suspended solids (>100 NTU)should be pre-flushed before using the PTSA sizing method to accurately determine the systemvolume. These elevated levels can interfere with the PTSA measurement. System flushing until nitriteresidual is below 100ppm or turbidity is below 40 NTU is recommended.The SP-350 can be used to check if the water is suitable for the method.
Volume (US Gallons) = (Ounces Added x 50,000) / (PTSA in pub Final – PTSA ppb Background)
Volume (US Gallons) = (Ounces Added x 250,000) / (PTSA in pub Final – PTSA ppb Background)
Volume (US Gallons) = (Ounces Added x 6250,000) / (PTSA in pub Final – PTSA ppb Background)
