Wastewater treatment systems for compressor condensates

Wastewater treatment systems for compressor condensates serve to treat wastewater resulting from compressed-air generation in compressors to such an extent that the treated effluent can be introduced into public sewer system.

Regulatory framework

Wastewater treatment systems for compressor condensates 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:

Wastewater treatment systems for compressor condensates – Part 1 Gravity, filter and adsorption methods
(Anlagen zur Behandlung von Kompressorenkondensaten Teil 1: Schwerkraft-, Filter,- und Adsorptionsverfahren)


Wastewater treatment systems for compressor condensates – Part 2 Emulsion separation method
(Anlagen zur Behandlung von Kompressorenkondensaten Teil 2: Verfahren zur Emulsionsspaltung)

The approval principles covering this work area are not published, but are made available to the applicants during the procedure.

National procedure

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

No formal requirements apply. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).
