The tank materials listed in the standard for small sewage treatment plants are varied as the possible treatment processes. The materials allowed range from classic reinforced concrete, via fibre-reinforced plastics through to stainless steel.
All materials, or tanks manufactured from them, have to prove their suitability in terms of their intended use. In addition to the test for stability and water tightness, there also includes the proof of fire behaviour, durability and a leaching trial to verify if any dangerous substances are present.
PIA GmbH has partners and co-operative bodies throughout Europe and can provide the appropriate material tests and the required expertise, also in other European countries when desired.
Norway claims a “dynamic surface leaching test” to proof a possible release of dangerous substances (duration 64 days) from tank material by December 31st 2017. For further information please check here:
