Specification

Technical data

  • Nominal active surface - 41 m²
  • Operating pressure - 8.6 bar
  • Permeate volume - 53 m³/day
  • Stabilized salt rejection - 99.0 %
  1. Permeate consumption and salt (NaCl) rejection are indicated for the following test conditions: 2 000 mg/L NaCl, 25°C, pH 8, indicated pressure and 15% permeate recovery.  
  2. Flow rates of permeate for every specific element might vary, but will not fluctuate by more than 15% from the indicated values.

Operating conditions

  • Maximum operating water temperature - 45 °С
  • Maximum operating pressure - 41 °С
  • Maximum pressure drop - 1.0 bar
  • pH range, operational mode - 2...11
  • pH range, chemical cleaning mode - 1...12
  • Maximum feed silt density index SDI < 5
  • Free chlorine tolerance - <0.1 mg/L

Maintenance

Before launch of the reverse osmosis system preliminary preparation of the membrane, refill of the elements, adjustment of the devices and other system checks should be performed.

Avoid any major pressure or flow surges inside the spiral-wound elements in the middle of launch, stop, cleaning etc. to avoid risk of damage infliction to the membrane. During the launch it is recommended to gradually switch the system from standstill to operational mode following the steps:

  • gradually increase feed water pressure during 30-60 seconds
  • operational rate of the flows should be developed gradually during 15-20 seconds
  • permeate obtained within the first hour of operation is discharged

Important information

  • After the initial soaking always keep the elements wet.
  • To prevent biofouling during long operation breaks it is recommended to submerge the membrane elements into preservative solutions.
  • Maximum pressure drop along the full length of the housing makes 2.1 bar.
