| Title | Standard method for assessing and improving the energy efficiency of waste water treatment plants |
| Work Item Number | 00165335 |
| Abstract/Scope | This document defines a methodology for determining and assessing the energy efficiency of Waste Water Treatment Plants (WWTP). The methodology aims at describing, in a systematic way, the various steps required to establish the Water Treatment Energy Index (WTEI) of a particular WWTP. The methodology includes the classification of WWTPs in different types, identification of different stages of treatment, identification of key performance indicators (KPIs), overview of existing energy monitoring standards and the detailed description of the methodology, including a step by step guideline of how to apply and implement it. The methodology is divided in 2 sub-methods that should be selected and followed according to the following goals: - The Rapid Audit (RA) method allows for a quick estimation of the water treatment energy index (WTEI) based on existing information such as historical data pertaining to energy use records along with influent and effluent quality values. The aim of this methodology is to provide a WWTP energy benchmark, a rapid tool to identify energy efficiencies and inefficiencies so further actions can be planned, as well as to evaluate the impact of WWTP retrofitting. The Rapid Audit methodology is detailed step by step in Clause 4 of this TR and can be used as a standalone document. The application of the Rapid Audit methodology to one real WWTP is shown in Annex A. - The Decision Support (DS) method requires intensive monitoring across a WWTP of energy usage and water quality parameters that provides an accurate and detailed calculation of WTEI for each stage as well as its overall value for the plant. The goal of this assessment is to serve as a diagnosis of the functions/equipment in a plant that may lead to poor energy efficiency performance. The Decision Support methodology is detailed step by step in Clause 5 of this TR and can be used as a standalone document. The application of the Decision Support methodology to one real WWTP is shown in Annex B. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
In the case of undated standard, a link to the last dated version is provided.
In the case of series, a link to each standard identified in the series is provided.
We also invite you to check (via the website) whether corrigenda and/or amendments shall be read in conjunction with the main standard.
