Chemical precipitant storage vessel - constructed, pref. in the ground, from polyethylene components

摘要

A storage vessel for liq. and/or solid chemical precipitants, which is pref. sunk in the ground, has a precipitant-resistant barrier layer foil (2) of low pressure polyethylene with an inner barier layer (pref. of aluminium), applied onto any solid substrate material (1). An opt. precipitant-resistant polyethylene plate (4) has, on one side, ribs (3) which rest on the barrier layer foil (2). ADVANTAGE - The vessel is simple and inexpensive to mfr. and satisfies high safety requirements. Existing vessels can be modified in a simple manner.
