In these tests, we focused on the behavior of Polybar salt version in different water compositions.

-          Expansion in water with 3% NaCl (simulating sea water conditions)

-          Expansion in water containing 7% diammonium phosphate (simulating waste water with manure and slurry)

-         Chemical resistance against waste water infected by bacteria forming different acids: 3% Lactic acid + 0,5% Butyric acid + 1,5% Acetic acid.

The conclusion of all testing’s is that Polybar+ water version is a chemically resistant and functional expansion seal against wastewater contaminated with manure and slurry.
