Type T-CUT
PreparationforUse
The limit values for pressure and cross-flow rate must not be exceeded.
→
Ensure that the entire system (in particular the permeate areas of the modules) is deaerated.
→
Gradually increase the cross-flow rate and rinsing water pressure by carefully opening the feed valve further.
→
Adjust the trans-membrane pressure by carefully and gradually closing the valve on the concentrate outlet
(pressure sustaining valve).
→
Check connections of the module for leaks. If leaks are determined, stop the operation and take countermea-
sures (if the seal is correctly positioned, it is usually adequate to tighten the clamps hand-tight).
NOTE!
Damage to the connections.
▶ If the surfaces of the seals on the connector and supply line are not flat on top of one another, do not use
excessive force to tighten the connecting elements to ensure leak-tightness. Using excessive force may cause
the connections to break.
→
After rinsing, drain the system and start filtration.
There is usually the option of measuring the pressure drop through the module and the cross-flow rate of
the module from the system.
If the cross-flow rate of the module cannot be measured, the operating point is simply adjusted by slowly
increasing the pressure drop to its recommended value.
In any case, the concentrate outlet valve (pressure sustaining valve) must be closed enough for the concentrate
pressure on the module outlet to always be greater than 0.5 bar.
The cross-flow rate specified in the data sheets for the recommended pressure drop applies to water (temper-
ature 25 °C, viscosity 1 mPas). Please note that the maximum permissible pressure drop with feed solutions of a
higher viscosity is reached with a considerably lower cross-flow rate.
Please consult a representative of Bürkert Fluid Control Systems if you have questions surrounding the
preparation of the module for use.
