Overview
This European Standard specifies requirements, test methods, the marking and evaluation of conformity for a packaged and/or site assembled tertiary treatment unit for installation either separately or in a pre-existing unit. It applies for tertiary treatment units that are placed on the market as complete units used for the tertiary treatment of domestic wastewater by biological, physical, chemical, electrical processes and coming from: a) units in accordance with EN 12566-3 or EN 12566-6; b) installations designed and constructed in accordance with CEN/TR 12566-5. Equivalent secondary treated effluent may come from existing systems. Package and/or site assembled tertiary treatment units according to this standard consist of one or more watertight tank(s) without any direct infiltration into the ground, made of concrete, corrosion resistant or coated steel, un-plasticised poly-vinyl chloride (PVC-U), polyethylene (PE), glass reinforced thermosetting plastics (GRP) based on polyester resin (UP) (GRP-UP), polypropylene (PP) and polydicyclopentadiene (PDCPD). This document (EN 12566-7:2016) has been prepared by CEN/TC 165 "Waste water engineering", the secretariat of which is held by DIN (Germany). The responsible German standardization committee is Working Committee NA 119-05-04 AA "Kleinkläranlagen" ("Small type wastewater treatment plants") at DIN Standards Committee Water Practice (NAW).
