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)
