ATB-300 GL lining system is a shrink free modified system based on DERAKANE 470 epoxy vinyl ester.
Typical thickness 3mm, reinforced with chapped strand mat. Here the lining was applied on concrete surface.
Length: 60m (197ft)
Width: 50m (164ft)
Height: 5m (16ft)
There are also impellers in the basin to mix up the fluids thus there is also a mechanical impact on the applied ATB-300 GL lining system.
Being 20 years in service the lining is still performing strong.
Beside the chemical and heat resistance a great challenge is the high temperature range from minus during winter to almost boiling due to the process water.
By using the ATB-300 GL Honeycomb system expensive concrete repair can be prevented and drains included underneath the system, which has 2 functions:
– As a leak detection system
– To evacuate upcoming ground water
Inside the basin the temperature range is from +75°C (167°F) to +100°C (212°F), outside the basin it may be -20°C (-68°F) during winter season.
Process water at around 70°C (158°F) with upsets of 90°C (194°F).
The process water intake is always in between 90°C (194°F) and 100°C (212°F).
Varying pH value from 3 to 14.
