| Test Conditions | : | The stated performance is initial (data taken after 30 minutes of operation), based on the following conditions : 1500 ppm NaCl solution,applied pressure- 6.88 kg/ sq.cm2 (225 psig), operating temperature- 77 °F (25 °C) ,15% permeate recovery-15% and pH range 6.5 - 7.0 . |
| Note | : | Minimum permeate flow for individual elements may vary to + or - 15 percent of nominal. All membrane elements are supplied with a brine seal. Elements are vacuum sealed in a polyethylene bag containing a 1.5 % sodium bisulfite solution and 20% propylene glycol solution, and then packaged in a cardboard box. |
