The standard series EN 12566 “Small wastewater treatment systems for up to 50 PT“ contains the following parts (see Figure 1): Part 1: Prefabricated septic tanks Part 3: Packaged and/or site assembled domestic wastewater treatment plants Part 4: Septic tanks assembled in situ from prefabricated
27、kits Part 6: Prefabricated treatment units for septic tank effluent (the present document) Part 7: Prefabricated tertiary treatment units (in preparation) For filtration and infiltration systems, CEN/TC 165 decided to publish the following CEN Technical Reports, which are considered as Code of Pract

35、or EN 12566-4 in small wastewater treatment systems for up to 50 PT. NOTE Equivalent septic effluent may come from existing septic tanks. It applies to the prefabricated secondary treatment unit, where all its components are packaged or site-assembled and placed on the market as a kit by one manufac
36、turer. The prefabricated secondary treatment unit consists of one or more tanks made of concrete, steel, unplasticised polyvinylchloride (PVC-U), polyethylene (PE), glass reinforced polyester (GRP-UP), polypropylene (PP), polydicyclopentadiene (PDCPD) or container made of flexible sheets (PEHD, PP,
37、PVC, EPDM). Other components specified by the manufacturer, such as pipes, pumps and filter material will be considered as part of the unit. This standard establishes the performance of the prefabricated secondary treatment units needed to verify their suitability for the end use conditions for whic
38、h the test methods are specified. This standard applies for the packaged and/or site assembled secondary treatment units for use on the top of the ground (outside the building) or buried in the ground where no vehicle loads are applied to the unit. This standard does not cover: non watertight second
39、ary treatment units with direct infiltration into the ground; retrofit kits (see definition in 3.7). 2 Normative referencesThe following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable for its application of this document.
