Practical examples of how the SAERTEX-LINER® is used:


Airport:

Medium: Surface water containing kerosene and may be contaminated with de-icing medium in winter.

Typical waste water composition in winter:

Temperature: < 5 °C
Chemicals with concentration < 10 mg/l: Formiates
Ethylene glycol
Diethylene glycol
1,2 propane glycol
1,3 propylene glycol
Maximum temperature: 40 °C
pH value: 4 – 11

For sporadic loads and subsequent rinsing with clear water use SAERTEX-LINER® impregnated with polyester resin. In other cases and if the media remain in the pipe for longer (e.g. in depressions) use the SAERTEX-LINER® impregnated with vinyl ester resin.


Brewery:

Permanent temperature: 60 °C


Typical waste water composition during regular cleaning:

NaOH 0 – 4 % 65 °C
HCl 1 – 15 % 30 °C
HNO3 0 – 5 % 30 °C

pH value

0 -14

These chemicals are normally used during cleaning. Cleaning is carried out several times a week alternately with hot lye (NaOH) and cold acids (HCl/HNO3)
