Systems for limiting hydrocarbons in mineral oil containing wastewater with biodiesel, bio heating oil and ethanol contents

Systems for limiting hydrocarbons in mineral oil containing wastewater with biodiesel, bio heating oil and ethanol contents are systems for treating wastewater containing up to 100% biodiesel and bio heating oil and up to 10% ethanol.

Regulatory framework

Systems for limiting hydrocarbons in mineral oil containing wastewater fall under the Ordinance on the determination of the suitability of construction products and construction techniques under water law by means of verifications in accordance with the Building Codes of the federal states (WasBauPVO). 

Cf. WasBauPVO, Section 1(1)(g) 'Systems for limiting hydrocarbons in mineral oil containing wastewater'.

DIBt grants national technical approvals (abZ) in combination with general construction technique permits (aBG) for these systems. The abZ/aBG serve to verify the suitability of the systems both from a construction and water legislation point of view.

The following approval principles are currently available:
